I remember getting a late-night message from a sourcing agent in Europe. His shipment of sliding doors was stuck at customs because the specs didn’t match the declared load.
Turns out the manufacturer had cut corners without informing anyone.
That kind of misstep is why I’ve made it a priority to vet suppliers thoroughly. I don’t just look at price tags, I look at production history, export reliability, and how they handle problems.
In this article, I’ll introduce you to six Chinese sliding door manufacturers who’ve built a strong track record.
You’ll learn what makes each unique and whether they fit your sourcing needs.
If trust and long-term value matter to you, this list will save you hours of research.
So let’s get started!

1. Vallisco
Company Profile
- Address: Building 1, No. 1926, Cao An Highway, Jiading District, Shanghai, China 201824
- Website:https://vallisco.com
Vallisco may be a new name on the surface, but the team behind it carries over two decades of experience in door and window manufacturing.
As a subsidiary of Qeeka Home, which began its doors and windows business in 2000 and acquired its own factory in 2019, Vallisco officially launched as an independent brand in 2024 with a clear mission: serve high-end residential and boutique commercial projects with tailored fenestration solutions.
Headquartered in Shanghai, Vallisco is rooted in smart, high-precision production practices, serving clients across Southeast Asia and Europe.
Unlike companies focused on one-off transactions, Vallisco works with homeowners managing full replacements and professionals leading villa, hotel, and B&B builds.
If you’re in the business of hospitality or custom home development, Vallisco aligns with the kind of supplier relationship that delivers both performance and architectural cohesion.
Product Portfolio & Capabilities
- Versatile Sliding Door Systems: Vallisco offers sleek, functional aluminum sliding doors engineered for thermal insulation, structural strength, and weather resistance, perfect for upscale homes and boutique projects.
- Built for Whole-Home Solutions: Their lineup spans not only sliding systems but also casement, tilt-and-turn, folding, and fixed-frame windows, designed for cohesive architectural planning.
- High-Spec Glass Options: You’ll find double and triple-glazed variants, including Low-E and argon-filled models, ideal for meeting EU and Southeast Asian energy standards.
- Modern Aesthetic Meets Practical Function: Their design approach blends slimline aluminum profiles with high-performing sealing systems, providing both elegance and comfort.
- Flexible Application Scope: Whether it’s a greenhouse, coastal villa, or countryside inn, the product mix adapts well to both warm and temperate climates, something not all suppliers pull off with equal precision.
Services & Engagement Model
- Tailored for Project Buyers: Vallisco doesn’t cater to one-time buyers looking for a single window. They focus on villa owners, hotel developers, and project engineers who need consistency and scale across multiple openings.
- Personalized Project Support: From the first quote to final delivery, their team works closely with engineering leads or property owners to align on size, function, and aesthetic goals.
- Flexible Order Structure: Whether you’re a B2B buyer or a homeowner replacing several doors and windows at once, you’re treated like a partner, not a number in the system.
- Cross-Border Readiness: They’re fluent in export logistics, offering support for clients across Southeast Asia and Europe, with the flexibility to serve new international territories.
- Inspired by the Mannlee Model: Much like MannleeCo, Vallisco emphasizes clean design, strong customer support, and project reliability, minus the steep luxury markup.
Compliance & Quality Assurance
Vallisco may be young as a brand, but it’s built on top of years of certified production practices. As part of the Qeeka Home ecosystem, the company inherits a quality-first culture with a strong factory foundation acquired in 2019.
Their materials and components align with energy performance standards common in Southeast Asia and Europe, making it easy for clients to meet local regulations. While they may not yet boast a long list of flashy certifications, their operational track record and export-ready quality are a testament to quiet competence. They also offer comprehensive documentation and QC support to back up every project shipment.
Bottom Line
Vallisco is the ideal partner for villa owners, hotel developers, and residential project leads seeking reliable, design-forward door and window solutions. Their team understands the scale, the visual expectations, and the real-world logistics behind full-house or full-building installations. However, as a newer brand (despite older roots), Vallisco still has limited global brand recognition compared to long-established competitors.
2. Oppein Home Group Inc.
Company Profile
- Address: Oppein Headquarters, No. 366, Guanghua 3rd Road, Baiyun District, Guangzhou, China
- Website:https://www.oppeinhome.com
Oppein is one of those companies you hear about before you ever work with them. Their name comes up often in B2B conversations, especially if you’re sourcing interiors in bulk.
Founded in 1994, they started out just making kitchen cabinets. But today? They’ve scaled to become the largest cabinetry manufacturer in all of Asia.
Their footprint is huge, five major manufacturing centers spread across China. We’re talking over 2.3 million square meters of factory space. It’s not just scale though. It’s the level of integration and control that stands out.
And with over 8,700 showrooms around the world and more than 10,000 projects delivered globally, you can tell this brand is not just operating at scale, they’re doing it with consistency.
Product Portfolio & Capabilities
- Sliding Doors as Part of Integrated Systems: Oppein’s sliding doors aren’t sold as standalone architectural systems. They’re part of their full interior design ecosystem, made to match wardrobes and cabinetry.
- Material Choices That Fit Interiors: The doors use Titanium Magnesium Alloy frames and WPC panels, which are ideal for internal room dividers, closets, and wardrobes, not outdoor or structural openings.
- Customization That Works at Scale: Even though they handle massive order volumes, Oppein still manages to offer highly customized options in terms of materials, finishes, and configurations.
- Kitchen, Wardrobe, and Door Synergy: Their strength lies in bundling, kitchens, closets, doors, and furniture are all coordinated to deliver a seamless look across your entire space.
- Ideal for Multi-Unit Builds: If you’re working on large residential or hospitality developments, their product lineup makes it easy to source everything from one reliable vendor.
Services & Engagement Model
- Whole-House Customization Model: Oppein provides a start-to-finish solution, from initial design sketches to full-scale delivery and installation support, centered around their one-stop model.
- Developer-Focused Business Model: Their primary clients are large developers, contractors, and international franchise builders who need reliable fulfillment at scale.
- Project Management Support Built-In: They don’t just ship and disappear. Their backend systems and dedicated project teams help manage specs, revisions, and timelines with fewer headaches.
- Automated Manufacturing Infrastructure: With HOMAG and WEMHONER machinery at the core of their production lines, everything from cutting to finishing is optimized for speed and precision.
- Digital-First Order Handling: Their use of big data and cloud systems adds another layer of control, helping clients manage mass customizations without falling into chaos.
Compliance & Quality Assurance
Oppein doesn’t take shortcuts when it comes to compliance, and it shows. Their certifications span ISO 9001 for quality control, ISO 14001 for environmental responsibility, FSC for responsibly sourced wood, and CARB compliance to meet low-emission standards.
They’ve even gone the extra mile to secure GreenGuard certification, which isn’t that common in their category. And for government or institutional buyers, being a United Nations qualified supplier carries extra weight.
Bottom Line
Oppein is a powerhouse when it comes to large-scale, integrated interior furnishing, especially if you want to streamline procurement for multiple categories. But if you’re looking for high-performance, standalone exterior sliding doors, they may not have the specialization you’re after.
3. Kanod Windows
Company Profile
- Address: No.1, Yubu Village, Guanyao, Shishan Town, Nanhai District, Foshan City, Guangdong Province, China
- Website:https://www.kanodwindows.com
Kanod Windows is one of those names that keeps popping up in B2B conversations whenever someone needs durable, performance-driven sliding doors. They’re based in Foshan, China’s fenestration capital, and have over 28 years of experience under their belt.
What makes Kanod stand out isn’t just its longevity, but how deep it goes on the technical side.
Their factory size seems to vary depending on who you ask, anywhere from 20,000 to 30,000 square meters, but either way, they’ve built for scale, serving over 100,000 customers globally.
If you’re a builder, developer, or architect who likes to talk specs and tolerances, their site and sales material won’t disappoint. It’s all about metrics, ratings, and what their doors can actually withstand.
Product Portfolio & Capabilities
- Sliding Doors Built for Performance: Sliding doors aren’t a side offering here, they’re a core strength. Heavy-duty aluminum designs and smart-motion automation options are part of their regular lineup.
- Engineered Series That Deliver: Product lines like the SmartMotion, Bojue, Meigu, and 139 Series are built with structural integrity in mind. The 139 Series, for instance, features 2.0 mm wall-thick aluminum profiles and high-spec glass for insulation.
- Thermal & Acoustic Insulation by Design: Many of their models come with double-layer hollow tempered glass (e.g., 6mm+12A+6mm) that helps reduce noise and keep energy bills down.
- Architectural-Grade Materials: All sliding doors are constructed with 6063-T5 aluminum alloy, a material typically reserved for higher-end architectural use.
- Spec-Driven Communication: Kanod’s product descriptions always emphasize real-world performance, like 45+ dB soundproof ratings and verified wind-load resistance. They’re clearly geared toward buyers who want the numbers to back up the design.
Services & Engagement Model
- Flexible Business Models: Kanod is open to working through different channels, whether it’s direct retail, wholesale supply, or OEM manufacturing. You’re not locked into a one-size-fits-all relationship.
- Project-Specific Customization: They tailor each order based on performance needs, environmental conditions, and aesthetic goals. That balance of form and function really shows in their project approach.
- Multilingual Support Teams: You’re not left guessing. Their English-speaking sales and technical teams can walk you through pre-sale specs and offer post-installation advice if needed.
- End-to-End Coordination: From consultations to delivery, they handle the entire engagement like a partner, not just a product vendor. That’s especially helpful on overseas jobs with tight timelines.
Compliance & Quality Assurance
When it comes to quality, Kanod doesn’t cut corners. Their products are CE certified, making them viable for European projects that demand strict adherence to safety and environmental standards.
For domestic credibility, their glass units carry 3C certification, China’s mandatory safety mark for glass and glazing components.
Together, these certifications show that Kanod’s not just making promises, they’re building for global compliance. Their focus on certifying key components, especially around structural safety and thermal performance, tells you they’re in it for serious, spec-heavy projects, not just surface-level style.
Bottom Line
Kanod Windows delivers what a lot of other manufacturers only claim, solid, spec-based sliding doors engineered for real-world challenges. Their commitment to performance and material quality makes them a strong pick for commercial and high-end residential builds. That said, their highly technical orientation may not suit buyers looking for simple or budget-grade solutions.
4. Paiya
Company Profile
- Address: Nanhai District, Foshan City, Guangdong, China
- Website: https://www.paiyaworld.com/
Paiya is a brand you’ll often hear about when talking to local distributors and builders in China. They’ve been around since 1990 and were one of the early players to go all-in on aluminum door and window solutions.
Their presence is huge, four large manufacturing bases covering 300,000 square meters.
That kind of scale gives them the leverage to support over 1,200 specialty stores and 600 “Deep Comfort” showrooms across China.
Their website leans heavily into brand storytelling and emotional design, but behind all the soft messaging is a company deeply rooted in technical innovation and domestic market dominance.
Product Portfolio & Capabilities
- Sliding Doors with Engineering Roots: Paiya has a deep catalog of sliding doors, including advanced systems like hanging sliders and lift-and-slide designs. These aren’t just cosmetic, they’ve been engineering them for decades.
- Early Innovators in Door Tech: They were one of the first Chinese companies to develop insulating glass swing doors and hanging sliding doors, which says a lot about their long-term R&D investments.
- Diverse Series for Specific Uses: Products are broken into use-case categories, kitchen, balcony, living room, which makes it easy for builders to match form with function during planning.
- Aluminum as a Design Language: From folding doors to sunrooms, everything uses aluminum as a base material. And they finish it off with German wood grain heat transfer to create a broad visual palette.
- Flexible, But Structured Offerings: While their catalog is expansive, it’s also well-organized. You can see they’ve spent time refining their product lines for scale without sacrificing variety.
Services & Engagement Model
- B2B Support for a Domestic Dealer Network: Their core service model revolves around equipping their national dealer network with ready-to-go inventory, marketing kits, and design consultations.
- Franchise-Friendly Infrastructure: Paiya doesn’t just manufacture. They guide and grow a national sales army, complete with training, co-marketing, and branding support.
- Strong Consumer-Facing Focus: Their communication strategy clearly aims at the Chinese end user, but dealers and store owners are the real operational partners behind the scenes.
- Deep Brand Identity Integration: Their “Deep Comfort” philosophy plays out across product design and retail environment planning, helping franchisees deliver a consistent user experience.
- Limited International Playbook: While they don’t currently push hard for overseas markets, their structure could easily support export expansion through the right partner relationships.
Compliance & Quality Assurance
Paiya is recognized as a “national high-tech enterprise” in China, a designation that often signals a higher level of internal R&D and quality monitoring.
While international certifications like NFRC or AS2047 aren’t front and center, the company’s long-term market position implies rigorous domestic quality processes.
You’ll notice their branding leans heavily on domestic recognition, like being a CCTV-endorsed country brand, which reinforces their national trust and appeal. For those prioritizing Chinese market integration, this is a major plus.
Bottom Line
Paiya is a strong domestic brand with deep roots in aluminum door innovation, backed by solid infrastructure and consistent product development. But if you’re sourcing primarily for international export or need globally certified specs, you might find their documentation and support structure a bit localized.
5. Wanjia Window and Door
Company Profile
- Address: No.5 Songxing Road, Songgang, Shishan Town, Nanhai District, Foshan City, Guangdong Province, China
- Website:https://wanjiadw.com
Wanjia is one of those companies that’s managed to grow fast without losing its grip on quality.
Founded in 2012, it may be a younger brand compared to others, but their team brings over two decades of collective experience to the table.
They’ve gone from a small outfit to a sizable manufacturer with over 500 employees and a large-scale facility covering around 50,000 square meters. That’s no small feat for a company still in its first decade.
What really catches your eye is how global their mindset is. With exports to 150+ countries and a client base of over 100,000, they’re clearly not just focused on the domestic market.
Product Portfolio & Capabilities
- Sliding Doors for Every Spec: Wanjia is a go-to supplier for aluminum and vinyl/uPVC sliding doors. They cover thermal break designs, electric models, and heavy-duty lift-and-slide systems that can handle serious traffic and insulation needs.
- Series with Purpose: Their aluminum sliding doors include models like the 70 and 185 thermal series, and the 130 heavy-duty lift series. These aren’t just catalog fillers, they’re built for performance.
- Smart Details that Matter: Think multi-point locks, insulated profiles, weather sealing, and strong frame-to-glass ratios. These features make a difference on projects that care about energy use and durability.
- Beyond Sliding Systems: Wanjia doesn’t stop at doors. Their portfolio includes folding doors, casement windows, curtain walls, and even sunrooms, most of which offer double or triple glazing with Low-E coatings and argon-filled chambers.
- Options for Architects and Developers: If you need variety in materials and finishes, or you’re working on high-efficiency certifications like Passive House, they’ve got the SKUs to support it.
Services & Engagement Model
- One-Stop Project Flow: From that first inquiry to the final shipment, Wanjia covers every step, consulting, quoting, drafting, production, packing, and delivery. They even provide support for installation.
- MOQ Flexibility for Custom Samples: Not every order has to be massive. For smaller runs or samples, they offer no-minimum-quantity options on select models, which is a win for prototyping or staged rollouts.
- Dedicated Account Teams: Each client gets a team, sales, designer, support, plus access to one-on-one video calls and walkthroughs to help with installation or system configuration.
- Packaging Built for Overseas Shipping: Products are protected using strong wooden crates, so if you’re shipping across oceans, you won’t be dealing with damaged units on delivery.
- Catering to Both Residential and Commercial Jobs: They’ve structured their offering to support single-home builders just as easily as they support commercial developers or franchise contractors.
Compliance & Quality Assurance
Wanjia doesn’t just tick boxes, they’ve gone all-in on global compliance. Their product lines carry Energy Star, NFRC, and CSA marks for North America, as well as CE for Europe and AS2047 for Australia.
They also maintain ISO9001 certification for quality management and offer full documentation support for architects, developers, and compliance teams. This range of credentials makes them especially attractive if you’re sourcing for regulated or high-standard markets.
Bottom Line
Wanjia is a dynamic and well-rounded partner for businesses needing high-quality, certified fenestration products on an international scale. Their flexibility, technical capabilities, and export infrastructure make them easy to work with. However, if you’re strictly looking for ultra-luxury branding or ultra-niche architectural finishes, you may find their catalog geared more toward performance and value than exclusivity.
6. Mexin Doors & Windows
Company Profile
- Address: No.56 Baihe Road, Nanping Economy & Technology Developing District, Chongqing, China
- Website:http://www.mexindoors.com
If you’ve worked on a hospital build, a commercial tower, or an airport overseas, chances are you’ve come across Mexin products, whether you realized it or not.
This brand has been quietly powering institutional builds across the globe since the early 2000s.
Mexin Best was founded in 2002 as part of the broader Mexin Group, which itself dates back to 1989.
They’ve been export-focused since the beginning, reporting $17 million in global sales even before 2001, a sign that international standards have always been part of their game plan.
With more than 10,000 employees and production lines sourced from the U.S., Germany, and Japan, they’ve scaled with purpose. The R&D center in Los Angeles is another strong indicator that their mindset is truly global.
Product Portfolio & Capabilities
- Sliding Doors with Function First: Sliding doors are part of their offering, but not their headline act. Expect more emphasis on practical, secure installations than on decorative patio sliders.
- Security and Specialty Door Systems: Mexin is a leader in fire-rated, steel security, and hollow metal doors. These products are designed for places where performance and safety can’t be compromised.
- Diverse Commercial Lineup: From automatic garage doors to hospital-grade entryways, their catalog reads like a spec sheet for commercial planners. They also offer timber doors and system windows.
- Institutional Use is the Sweet Spot: Think hospitals, airports, schools, anywhere you need doors that meet local and international codes without fuss.
- Reliable Across Product Types: Their offerings aren’t about chasing trends. They’re focused on function, durability, and long-term ROI for builders and developers who prioritize utility.
Services & Engagement Model
- Full Chain Coverage: Mexin handles everything in-house, from R&D to production, marketing to after-sales support. It’s not just a product, it’s a complete pipeline.
- Solutions Built for Long-Term Use: Their mission is simple: build doors that last, protect, and stay in spec. You’ll find this mindset across their commercial and residential lines.
- Versatile Export Support: They know how to serve international markets. Whether you’re sourcing in Europe or the Middle East, their sales channels are well established and ready to support.
- Tailored Commercial Support: For institutional clients and industrial builds, their project assistance includes technical documentation, compliance support, and volume fulfillment.
- Global Presence, Local Adaptation: With B2B platforms like Alibaba and Made-in-China in their toolkit, they’re well-positioned for fast quote turnaround and onboarding for global clients.
Compliance & Quality Assurance
If you care about certifications, and you should, Mexin brings one of the strongest portfolios on this list. They’re ISO9001-certified for quality systems, UL and WHI-certified for the U.S. market, BS-marked for the UK, CE-approved for Europe, and GA-compliant for China’s fire safety standards.
This level of compliance is more than marketing. It’s a necessity for the types of projects they serve. Whether you’re bidding on a municipal contract or supplying a multinational client, these credentials help you move faster through the red tape.
Bottom Line
Mexin Best is the definition of reliable when it comes to institutional and safety-first door systems. Their track record, certifications, and scale make them a trusted option for large, spec-heavy projects. That said, if your project is focused on premium aesthetics or designer glass sliding doors, their catalog might feel too utilitarian for your needs.
7. Phonpha Doors & Windows
Company Profile
- Address: No.14, Changtun Road, Nanyu Village, Denggang Industrial Zone, Lishui Town, Nanhai District, Foshan, Guangdong, China
- Website:https://www.phonpa.com
Phonpha is the kind of brand that quietly signals luxury without shouting about it. Established in 2007, they’ve consistently positioned themselves at the high end of the aluminum doors and windows market in China.
They operate two large production bases in South China, with a combined manufacturing footprint of over 80 acres.
Their reach across China is strong too, more than 800 dealer-operated stores help them maintain an impressive domestic presence.
If you’re looking for a supplier that mixes sleek aesthetics with advanced sound insulation and brand credibility, Phonpha sits comfortably in that lane.
Product Portfolio & Capabilities
- Stylish Sliding Doors with Substance: Their sliding door lines, like the “Danube River Narrow Fan Sliding Door,” are designed with modern silhouettes and built to dampen noise effectively, perfect for urban and high-end residential use.
- Award-Winning Design Recognition: Phonpha’s design quality isn’t just local, it’s globally recognized. Their products have taken home honors like the London Design Award and the American Good Design Award.
- Systemic Product Line Integration: They don’t just make doors. Their system includes windows, curtain walls, and sunrooms that share a consistent look and technical spec alignment.
- Energy-Efficient Build Focus: Their doors and windows are engineered for thermal insulation and long-term performance. You’ll see a clear emphasis on energy ratings and sustainable materials.
- Balance of Function and Form: Unlike suppliers that lean too heavily on engineering or just surface-level appeal, Phonpha blends both, especially suited for developers aiming for architectural impact.
Services & Engagement Model
- One-Stop Customization Capability: Phonpha controls R&D, design, production, and sales under one roof. This gives them tight control over timelines and spec consistency across every order.
- Elevated Installation Experience: Their “Five-Star Installation Standard” reflects their high-touch approach. They don’t treat install support as an afterthought, it’s part of the brand promise.
- Brand-Backed Trust Signals: As the official partner of the Olympic Council of Asia and supplier to the 2022 Hangzhou Asian Games, Phonpha has leaned into prestige branding to build buyer confidence.
- Global-Ready Platform: While their local focus is strong, they maintain English-language resources and an Alibaba storefront, indicating an active effort to engage overseas clients.
- Premium Positioning in Action: Whether it’s visual branding or service packaging, every part of their offer is designed to reinforce the premium tier they’re aiming for.
Compliance & Quality Assurance
Phonpha has the paperwork, and infrastructure, to back up its quality claims. Dual certifications from CE (Europe) and STANDARDSMARK (Australia) open the door to global market access.
Domestically, their National High-tech Enterprise status, National Green Factory designation, and CNAS-certified lab point to a serious commitment to innovation, sustainability, and compliance. They also meet ISO9001:2008, ISO14001:2004, and GB/T28001-2001 standards, rounding out their compliance profile with the foundational systems global buyers want to see.
Bottom Line
Phonpha is an ideal partner for upscale residential and commercial projects that demand aesthetic finesse, certified performance, and brand prestige. Their award-winning designs and reliable production infrastructure make them easy to recommend. That said, their focus on premium positioning may not align with cost-sensitive or entry-level project needs.
