I’ve spent weeks comparing sealing door suppliers in China, only to find that many promises didn’t hold up. Some said they could deliver quickly but missed deadlines. Others had great-looking catalogs but disappeared when it came to after-sales support.
If you’ve gone through this, you already know how stressful it is to make a decision without solid, reliable information.
Over time, I’ve worked side by side with engineers, contractors, and hotel owners facing the same struggle. Through site visits, hands-on research, and real project experience, I’ve seen firsthand which manufacturers stand by their word and which ones don’t.
In this article, I’ll share 8 sealing door manufacturers in China worth your attention. You’ll see their strengths, limitations, and the types of projects they fit best so you can judge with confidence.
My goal is to give you a clear and practical review that helps you identify and evaluate sealing door manufacturers in China you can actually rely on for construction and renovation.
Let’s dive in!
Quick Comparison Chart
Before diving deep, here’s a quick side-by-side view of all eight sealing door manufacturers. Think of it as a snapshot before we break down the details.
| Manufacturer | Location (Country) | Global Presence | Specialty Products | Limitation / Not Ideal For | Best For |
| Vallisco | Shanghai, China | Southeast Asia, Europe, other regions | Aluminum doors, airtight doors, energy-saving windows | Not ideal for one-off single door orders | Multi-room projects, villas, hotels |
| Deper Door Control Technology Co., Ltd. | Jiangsu, China | Domestic + International hospitals & labs | Automatic sliding, swing, hermetic, revolving doors | Wide range can confuse buyers if requirements are not clear | Hospitals, labs, high-traffic public spaces |
| Panpan Security Industries | Liaoning, China | Strong China presence + exports | Security doors, fire-rated doors, armored doors | Focused on bulk supply, less flexible for small orders | Large residential & hotel developments |
| Wangli Security & Surveillance | Zhejiang, China | Nationwide network + overseas reach | Security doors, wooden doors, smart locks, engineering doors | Mass production focus, limited high-specialization | Developers needing reliable bulk supply |
| Mexin Group | Chongqing, China | Domestic and global projects | Security doors, fire-rated doors, interior & engineering doors | Custom requests can move slowly in a large company | High-volume housing & infrastructure builds |
| TATA Wooden Door | Beijing, China | Nationwide retail, limited exports | Noise-reduction doors, fire-rated, warm-core, interior wooden doors | Mainly focused on China retail, weaker export services | Stylish interior & noise-reduction projects |
| OPPEIN Home Group | Guangzhou, China | Over 100 countries worldwide | Interior wooden doors, aluminum systems, full-house solutions | Pricing higher than smaller specialized suppliers | Full-house solutions & international buyers |
| Shandong Moenke Door Industry | Shandong, China | Mainly domestic, growing overseas | Hermetic doors, ICU doors, radiation-proof doors | Young brands with fewer global references | Hospitals, cleanrooms, medical facilities |
Now that you’ve got the snapshot, let’s dive deeper into each manufacturer and see what they really bring to the table.
1. Vallisco
I’ve dealt with suppliers that looked good on paper but fell short in reality. Vallisco feels more dependable. It started under Qeeka Home, which was founded in 2007, and expanded after acquiring a doors and windows factory in 2019. In 2024, Vallisco became an independent brand, carrying over 24 years of manufacturing experience.
Headquartered in Jiading District, Shanghai, Vallisco focuses on providing complete door and window solutions. Its main markets are Southeast Asia and Europe, though the company accepts orders from other regions as well.
Product Range
- Aluminum Alloy Doors: Sleek, durable designs with strong sealing performance. They work well in environments that demand energy efficiency and resistance to harsh weather.
- Airtight Doors: Built with precision frames and sealing strips. These doors are used when airflow control and stable indoor conditions are critical.
- Soundproof Doors: Engineered to reduce noise transfer between spaces. A practical choice for hotels, inns, or private residential projects.
- Energy-Saving Windows: Frames paired with insulated glass and thermal breaks. They help cut heat loss while still maximizing natural light.
Reputation & Certifications
The company emphasizes CE and ISO compliance, which adds credibility to its sealing and safety performance. Although Vallisco is a relatively new brand name, its connection to Qeeka Home supports a stronger reputation.
Services & Support
- OEM/ODM Production: Vallisco supports custom designs and private labeling. This is useful if you need your own brand applied to door and window solutions.
- Technical Drawings: Professional drawings and detailed specs are provided. These help installers work faster and avoid errors.
- Export Assistance: Packaging previews and shipping support are available. This gives you clarity before confirming large orders.
- Consultation Service: Product specialists guide you in selecting the right solutions. This saves time when balancing cost, durability, and design.
Final Thoughts
Vallisco is a good choice if you want one supplier for both aluminum systems and specialized sealing doors. However, since the brand mainly serves larger projects, it may not be the best fit if you only need a single door or window; they are better suited when you’re replacing several units at once.
2. Deper Door Control Technology Co., Ltd.
Deper was founded in 2001 and has since grown into one of China’s recognized makers of automatic doors. Based in Dongtai, Jiangsu Province, they operate from a facility covering 68,000 m². With over 20 years of experience, they supply public buildings, hospitals, and commercial projects around the world. Their reputation is built on a focus for airtight and hermetic doors critical for medical and cleanroom applications.
What stood out to me when I first learned about them was how often their doors are chosen for healthcare projects. That tells you they’re trusted in environments where failure simply isn’t an option.
Product Range
- Automatic Sliding Doors: Designed for high-traffic areas where efficiency matters. These reduce bottlenecks and minimize wear compared to manual systems.
- Automatic Swing Doors: Equipped with sensors and safety features. They are well-suited for spaces where accessibility is important.
- Hermetic Doors: Airtight doors developed for hospitals and labs. They help control airflow and reduce contamination risk.
- Revolving Doors: Provide thermal insulation and energy savings. They also create a modern appearance for commercial entries.
Reputation & Certifications
Deper highlights CE and ISO compliance across its product lines. Their consistent presence in international projects reinforces a reputation for reliability.
Services & Support
- Design & Engineering: Offers tailored solutions for varied building needs. This flexibility is valuable for custom projects.
- Installation Guidance: Provides manuals and technical support. That helps contractors finish faster and avoid delays.
- After-Sales Service: Maintenance and spare parts are available to extend product lifespan.
- Export Capability: Experienced in international shipping with proper documentation and packaging.
Final Thoughts
Deper is a reliable choice if you need airtight or automatic door solutions that can stand up to strict performance standards. However, product options can be broad, so you’ll want to specify requirements—like airflow, sealing, or pressure class early in the discussion to avoid surprises.
3. Panpan Security Industries
Panpan Security Industries was founded in 1982 in Yingkou, Liaoning, and has grown into one of China’s largest door manufacturers. In 2009, the company became part of ASSA ABLOY, giving it access to stronger resources and international expertise.
Today, Panpan operates multiple production bases and supplies both residential and commercial projects. With decades of experience, the company has built a reputation for delivering reliable security and fire-rated door solutions across China and beyond.
Product Range
- Security Doors: Reinforced steel doors built to resist forced entry. I’ve walked through developments using Panpan doors, and their solid build is noticeable right away.
- Fire-Rated Doors: Engineered to withstand fire for set durations. These are often chosen for hotels and large commercial projects with strict safety codes.
- Armored Doors: High-security models designed for banks or government facilities. They combine durability with professional finishes.
- Engineering Doors: Custom solutions for developers who require consistent quality across large projects.
Reputation & Certifications
Panpan helped draft national standards for security doors in China. Their certifications in fire resistance and safety are widely recognized, strengthening their reputation at home and overseas.
Services & Support
- Engineering Supply: Designed for large real-estate and infrastructure projects.
- Custom Options: Product specs can be adjusted to meet different building needs.
- Distribution Network: Strong presence in China with growing export reach.
- After-Sales Support: Installation and maintenance assistance available.
Final Thoughts
Panpan is a proven option if your project demands long-lasting security or fire-rated doors backed by industry experience. However, since they prioritize bulk orders, smaller projects or highly specialized customization may not receive the same level of attention
4. Wangli Security & Surveillance Product Co., Ltd.
Founded in 1996 and headquartered in Yongkang, Zhejiang, Wangli has grown into a well-known Chinese manufacturer specializing in security and surveillance doors. The company is publicly listed on the Shanghai Stock Exchange, which reflects both its scale and financial stability.
Wangli operates multiple facilities with advanced production capabilities. Its product lines cover residential, commercial, and industrial needs, making it one of the most recognized names in China’s door manufacturing sector.
Product Range
- Security Doors: Reinforced steel doors designed for intrusion resistance. I’ve seen them installed in residential complexes where reliable protection was a top priority.
- Wooden Doors: Crafted with a variety of finishes. These are widely used in interior applications for their durability and design options.
- Smart Locks: Integrated locking systems that add convenience and digital access control. They pair seamlessly with Wangli’s security doors.
- Engineering Doors: Large-scale doors customized for property developers. These provide consistent quality across big housing projects
Reputation & Certifications
Wangli has earned a strong reputation in China’s security door industry, partly because it helped shape national standards for locks and doors. Being a listed company also gives buyers confidence, since financial transparency is not common among manufacturers.
I’ve heard their name mentioned often in construction circles, which shows how widely their products are recognized for reliability.
Services & Support
- Project Supply: The company can handle bulk orders for housing, hotels, and infrastructure. Their capacity makes them reliable for meeting strict deadlines.
- Customization: Product dimensions and features can be tailored to project needs. This flexibility is useful when architectural designs vary.
- After-Sales Service: Maintenance and repair support is available. This helps extend product lifespan and maintain performance.
- Distribution Network: A nationwide sales and service presence ensures availability. International exports are also supported through established channels.
Final Thoughts
Wangli is a strong candidate if your project calls for large-scale security door solutions backed by a public company’s stability. However, their focus is mainly on mass production, so highly specialized customization may require extra coordination.
5. Mexin Group
Mexin Group was founded in 1989 in Chongqing and has become one of China’s leading door manufacturers. Over the years, it has expanded production to cover security, fire-rated, and interior door categories, supplying both domestic and overseas projects.
With multiple factories and a strong distribution network, Mexin can handle large-scale orders for residential, commercial, and infrastructure projects. The company’s long track record makes it a trusted partner for contractors who want both volume capacity and reliable performance.
Product Range
- Security Doors: Built from reinforced steel and designed to resist forced entry. These are widely chosen for apartment blocks and housing projects.
- Fire-Rated Doors: Engineered to provide fire resistance for set time periods. They are essential for meeting building codes in hotels and public facilities.
- Interior Doors: Offered in a variety of designs and finishes. They provide functional solutions while contributing to interior aesthetics.
- Engineering Doors: Tailored for property developers who need uniform quality. These models are produced in bulk for consistency across large projects.
Reputation & Certifications
Mexin has built a reputation as a dependable brand in both domestic and export markets. Its certifications for safety and fire resistance reflect a focus on compliance, but what really stands out is the scale of projects that carry its name from airports to hotels. That kind of exposure reinforces its credibility far more than certificates on paper.
Services & Support
- Bulk Supply: Large production capacity allows Mexin to fulfill major orders quickly. This is especially valuable for developers working on tight timelines.
- Customization: Product specs and finishes can be adjusted. This gives flexibility for projects with diverse design requirements.
- Export Experience: Years of overseas deliveries mean packaging and documentation are handled smoothly. That reduces friction in logistics.
- After-Sales Service: Maintenance and support are available. These services help extend product life and maintain reliability.
Final Thoughts
Mexin is an appealing option if you need a manufacturer with proven scale and visible project references. However, I’ve noticed that with companies this large, smaller custom requests sometimes take longer, so it’s best suited for projects that value capacity over hyper-specialized detail.
6. TATA Wooden Door
Founded in 1999 and headquartered in Beijing, TATA Wooden Door has become one of China’s best-known interior door manufacturers. The company is widely credited for popularizing the concept of “quiet doors,” which use soundproofing technology to reduce noise transfer between rooms.
Over the past two decades, TATA has grown into a national brand with multiple production bases and retail outlets across China. Its focus on innovation and everyday usability has helped it stand out in the crowded interior door market.
Product Range
- Noise-Reduction Doors: Built with acoustic cores and sealing strips. These doors are used in homes and hotels to create quieter, more comfortable spaces.
- Fire-Rated Doors: Manufactured to meet fire safety codes. They are commonly specified for high-rise residential and commercial projects.
- Warm-Core Doors: Designed with insulation materials. They help maintain indoor temperatures and reduce energy costs.
- Interior Wooden Doors: Offered in a variety of finishes and designs. They suit both modern and traditional interiors.
Reputation & Certifications
TATA is best known for its strong emphasis on noise control, which is something you actually notice when you step into a room fitted with one of their doors. That real-world difference is more convincing than any brochure. The company also holds fire resistance and environmental safety certifications, reinforcing its role as a trusted brand in China.
Services & Support
- Measurement Service: On-site measurement and design consultation are available. This ensures installations align with exact project requirements.
- Customization: A wide selection of finishes and features is offered. It gives flexibility when aligning doors with project aesthetics.
- Retail Network: Outlets across China make products and support easily accessible. Local availability helps shorten lead times.
- After-Sales Care: Dedicated maintenance services are provided. These help extend product life and performance.
Final Thoughts
TATA is a smart choice if you’re looking for stylish interior doors with proven noise-reduction performance. However, because their business is heavily focused on China’s domestic retail market, international buyers may find fewer export-oriented services compared to project-driven manufacturers.
7. OPPEIN Home Group
Founded in 1994 in Guangzhou, OPPEIN has grown into one of the largest home furnishing and building product manufacturers in China. The company began with kitchen cabinets and later expanded into doors, windows, wardrobes, and full-house solutions.
Today, OPPEIN operates several large-scale factories and exports to over 100 countries. Its ability to supply both residential and commercial projects at scale has made it a recognized global brand in home improvement and building products.
Product Range
- Interior Wooden Doors: Wide variety of designs and finishes. They combine style with everyday functionality.
- Aluminum Doors and Windows: Durable, energy-efficient systems suited for modern buildings. These products are often paired with OPPEIN’s whole-house packages.
- Wardrobes and Cabinetry: Storage solutions that integrate with door and window systems. This creates a cohesive look in residential projects.
- Customized Packages: Full-house solutions where doors, windows, and furniture are supplied together. This reduces coordination across multiple suppliers.
Reputation & Certifications
OPPEIN has built a strong reputation as a listed company on the Shanghai Stock Exchange. It holds multiple quality and environmental certifications, but what makes it stand out is the scale of its showrooms and international presence you see their name pop up in many different markets.
Services & Support
- Project Support: OPPEIN offers one-stop solutions, which I find particularly useful because it reduces the hassle of juggling multiple vendors. Having worked on a project where doors and cabinetry came from one source, consistency in design saved us a lot of time.
- Customization: Product finishes and styles can be tailored to match project requirements. This is especially helpful for residential developers.
- After-Sales Service: Dedicated support teams handle installation and maintenance. Clients benefit from a well-structured service network.
- Export Network: With experience shipping worldwide, OPPEIN provides proper documentation and secure packaging. This makes international procurement more straightforward.
Final Thoughts
OPPEIN is ideal if you want a supplier that can handle both scale and variety, especially when bundling doors with other home products. However, because of its size and brand-driven model, pricing may be higher than smaller manufacturers that focus only on doors.
8. Shandong Moenke Door Industry
Moenke is one of those companies that doesn’t try to do everything and that’s what makes it interesting. Instead of spreading across every type of door, they’ve chosen a very specific focus: airtight and medical-grade solutions. In an industry full of generalists, that kind of clarity stands out.
Founded in 2016 in Jinan, Shandong Province, Moenke may be younger than many competitors. But sometimes youth is an advantage. Their facilities are modern, their processes are fresh, and their products reflect today’s hospital and laboratory needs instead of old models being repurposed.
Product Range
- Hermetic Doors: Designed to stabilize pressure in operating rooms and labs. You can think of them as the invisible barrier that keeps space sterile.
- ICU Doors: Sliding and swing options with smooth, quiet operation. They’re made to keep the environment calm around critical care areas.
- Radiation-Proof Doors: Lead-lined designs for imaging rooms. They shield staff and patients while still being practical to use daily.
- Cleanroom Windows: Airtight glass panels that add visibility. They maintain pressure control without breaking the seal.
Reputation & Certifications
What gives Moenke credibility isn’t just its certifications though those boxes are checked. It’s the way their products are repeatedly chosen by hospitals and labs. That kind of real-world trust says more than any certificate ever could.
Services & Support
- Design Consultation: Engineers help match doors with strict project standards. That saves time in the planning stage.
- Customization: Sizes, sealing grades, and finishes can be adjusted. Flexibility matters when every hospital layout is different.
- Installation Guidance: Manuals and support reduce errors during setup. Projects finish faster when installers have clear help.
- After-Sales Care: Ongoing service is available. In medical settings, downtime isn’t an option, so this support is critical.
Final Thoughts
Moenke is a strong fit if your project involves hospitals, labs, or cleanrooms that demand airtight sealing and radiation protection. However, as a relatively new company, they have fewer long-term case studies and less export experience than older competitors, which means you’ll need to double-check project references and confirm support before committing.
