A few years ago, I had to replace five damaged security doors in a villa in China before guests arrived. It was stressful and expensive.
That job made me realize how much it depends on choosing the right manufacturer from the start.
Since then, I’ve interviewed building contractors, reviewed supplier delivery records, checked certifications, and followed up on after-sales service claims from real buyers.
This article gives you a simple list of 7 reliable security door manufacturers in China. You’ll find the details you need to make a smart choice for your projects.
If you build or manage properties, this guide is for you.

Let’s go section by section and take a closer look at what each of these manufacturers brings to the table.
1. Vallisco
Vallisco was established in 2024 as part of a larger door and window group with years of experience in home improvement and export manufacturing. They’re based in China and focus on factory-direct supply for villas, hotels, and residential projects, mainly in Southeast Asia and Europe.
I’ve followed their launch closely and can say they’ve built solid systems for reliable delivery, product matching, and export support, even as a newer name in the market.If you’re a builder or property owner tired of supplier delays or product mismatches, you’ll probably find Vallisco a breath of fresh air.
Product
- Aluminum Doors: Vallisco offers sleek, modern aluminum door systems suitable for villa entries, balconies, and patios. They’re built for strength, corrosion resistance, and long-term performance.
- Sliding Doors: They provide large-panel sliding door sets that work well for modern spaces needing wide, open transitions. These are great for hotel lounges or residential patios.
- Folding Doors: Their folding designs are perfect for large openings or spaces needing flexibility between indoor and outdoor areas.
- Glass Panel Doors: These combine aluminum frames with tempered or laminated glass. They give buildings a premium, clean look without compromising on strength.
- Custom Sizing: Vallisco allows sizing adjustments, making them a fit for projects that don’t want to compromise design for standard dimensions.
Quality Control
- Factory-Direct Shipping: You’ll get products directly from their production site, reducing miscommunication and cost issues.
- Export Readiness: Their systems are already built around Southeast Asian and European shipping standards, which lowers risk for your delivery timeline.
- Pre-Shipment Checks: Each order goes through visual inspections before being packed, which helps avoid rejections at customs.
- Sample Matching: What you see in their product samples and photos lines up with what gets delivered, based on what I’ve seen.

Takeaways
Vallisco is best for businesses sourcing aluminum doors and windows for villas or hotels that need modern looks and consistent export support. But if you’re just placing one order for a single house or need detailed customization for a small build, they might not be the right fit.
2. Zonle Doors Manufacturer Co., Ltd.
Zonle Doors was established in 2001 in Nanning, Guangxi, China. I’ve seen how they grew into one of China’s largest door producers, now covering 900,000 m² with four factory bases. They focus on security doors, fire doors, steel doors, wooden doors, and WPC doors for global B2B clients that need volume and consistency.
If you’re a project owner or developer working on multi-unit builds or hotel chains, you’ll appreciate Zonle’s scale and export capacity. I’ve tracked their evolution, they expanded into automated production early and added labs and accessory shops to improve quality and delivery speed.
Product
- Steel Security Doors: These heavy-duty doors offer anti-theft and impact resistance for residential or hotel entrances. They come with CE, CCCF, and anti-theft testing reports to meet international standards.
- Fire-rated Doors: Zonle produces steel and wooden fire doors rated for 30‑120 minutes. These are ideal for public buildings like schools, hospitals, and emergency exits.
- WPC Doors: Their WPC (wood-plastic composite) doors resist moisture and termites, perfect for humid climates or interiors. These work well for villas and hotels.

Takeaways
Zonle works well if you need large-scale orders of security, fire-rated, or composite doors with predictable lead times and factory control. But if you’re managing a small villa project or looking for flexible one-off orders, they may not be the best match.
3. Buyang Group Co., Ltd.
Buyang Group was founded in 1992 in Yongkang, Zhejiang Province, often called the door manufacturing hub of China. With over 5,000 employees and 600,000 m² of production space, they serve clients in over 70 countries. They’ve grown into a trusted name in steel security doors, fire-rated doors, and smart lock systems.
What impressed me early on was their investment in automated lines and in-house research. If you’re running large projects and need doors at scale without sacrificing quality, Buyang is worth a look. Their product consistency and national certifications make them a strong pick for builders and distributors alike.
Product

Takeaways
Buyang serves well when you’re running large-scale construction and need certified security doors with smart lock integration and fast delivery. On the flip side, if your project needs only a few units or highly bespoke decorative finishes, their strength in volume production may not match niche design needs.
4. Simto Door
Simto Group was founded in 1998 in Yongkang, Zhejiang Province, known locally as the hub of door manufacturing in China. Their factory spans roughly 250,000 m² and employs over 3,000 staff, producing thousands of doors each day. They specialize in secure entry systems, fire-rated models, and interior doors for commercial and residential builds.
I’ve seen how their flexibility benefits builders like you, offering both mass production and project-based customization. If you’re managing mid- to large-scale property builds and care about smart access or matched interiors, Simto brings strong value.

Takeaways
Simto is a strong choice for projects that demand secure access, smart lock integration, and a mix of classic and advanced door systems. But if you’re managing a very basic or low-cost job where tech features aren’t needed, their advanced capabilities might be more than you require.
5. KKD GROUP CO., LTD.
KKD Group was founded in 2007 and is based in Yongkang, Zhejiang Province, China’s top hub for door production. With six manufacturing bases covering around 200,000 m² and 1,500 employees, they turn out up to 5,000 doors daily.
I’ve heard from B2B partners that KKD provides everything from standard doors to luxury villa systems under its own brand.If you’re overseeing a multi-building project or managing properties for developers, having a one-stop supplier like KKD can simplify procurement.
Product
- Luxury Entrance Steel Security Door: These doors feature reinforced frames, anti-pry locks, and high-end finishes. Ideal for reception areas or upscale hotel projects.
- Villa Doors: KKD offers wide-panel villa doors in steel or wood-steel composites. Great for large homes or boutique resorts as part of whole-house packages.

Takeaways
KKD delivers solid value when your project needs a full suite of doors with scalable pricing and global export support. On the other hand, if your order is just a couple of units or requires highly decorative hand-crafted design, a smaller specialist supplier might serve you better.
6. Shandong Moenke Door Industry Co., Ltd.
Shandong Moenke was established in 2016 in Jinan, Shandong Province, China. Their facility spans about 15,300 m² and they employ over 225 skilled technicians. They focus on supplying hospital-grade and clean-room doors, including secure steel and sensor‑enabled systems for medical and industrial clients.
I learned about Moenke through facility visits and feedback from engineering teams working in hospital and lab projects. If you’re sourcing security doors for healthcare or clean environments, Moenke’s technical focus sets them apart.
Product

Takeaways
Moenke suits projects where you need secure, sensor‑enabled or medical-grade doors with airtight and radiation-rated features. In contrast, if your project is a standard villa or hotel without technical requirements, their specialized focus may make them less cost‑effective or flexible for general security door needs.
7. Zhejiang Tofine Commercial and Trade Co., Ltd.
Zhejiang Tofine was founded in 2009 in Jinhua (Yongkang City), Zhejiang Province, a well-known region for metal door manufacturing. Their factory spans over 20,000 m² and supports a monthly output of 20,000 doors, including security, fire-rated, stainless steel, and interior models. They export to more than 30 countries and work with wholesalers, builders, and developers.
What stood out to me was their ability to balance volume and variety without compromising reliability. If you’re managing multiple builds or supplying retail markets, their structured approach makes large-scale orders more manageable.
Product
- Steel Security Door: These are high-strength entry doors with anti-theft features and CE-rated construction. They fit hotel, residential, and villa projects requiring basic but reliable security.
