A door is the first impression of any property. We help global developers and wholesalers source Steel Security Doors, Interior Wood Doors, and Fire-Rated Doors from China’s specialized industrial clusters. We look inside the door panel to verify the core material, ensuring security, soundproofing, and durability.
Sourcing from the Source: Yongkang & Jiangshan
China’s door manufacturing is highly regionalized. We take you directly to the source based on your material needs:
- Yongkang, Zhejiang (The Capital of Hardware): The global hub for Steel Security Doors, Metal Fire Doors, and Armored Doors. If you need exterior entry doors with complex locking systems, this is the place.
- Jiangshan, Zhejiang & Guangdong: The centers for Interior Wooden Doors, WPC (Wood Plastic Composite) Doors, and PVC Doors. These regions specialize in aesthetics, painting finishes, and moisture-proof technologies.
- Foshan, Guangdong: The leader for High-end Aluminum Patio Doors and heavy-duty sliding systems.
HSY Sourcing navigates these distinct regions to find the factory that specializes in your specific door type, rather than a generalist trading company.
What Lies Beneath the Surface?
A door can look heavy but be filled with cardboard. B2B importers often face these hidden quality issues:
- The “Honeycomb” Trap: Factories claiming “Solid Wood Core” but delivering hollow doors filled with cheap honeycomb paper. We audit the cross-section to verify the Infill Material.
- Fire Rating Failures: Fake UL or EN certificates are common. We verify the factory’s Intertek/BM TRADA certification and check the density of the fire-proof perlite board.
- Moisture Deformation: Wooden doors swelling or warping in humid climates. We check the Moisture Content (MC) of the timber and the quality of the edge banding.
- Pre-hung Fitment: Frames that don’t match the door slab. We assemble random sets at the factory to ensure the hinges and latches align perfectly.
Door Solutions We Manage
Exterior Entry Doors: Steel security doors, cast aluminum doors, and fiberglass entry doors.
Interior Doors: Solid wood, MDF painted, Melamine, and WPC (Waterproof) doors.
Fire-Rated Doors: Steel and wood fire doors meeting UL 10C or BS 476 standards (20min to 180min).
Special Function Doors: Hospital doors, soundproof studio doors, and industrial rolling shutters.
Hardware Accessories: Sourcing compatible handles, hinges, closers, and smart locks.
Our Technical Audit & Packing Protocol
Doors are bulky and prone to surface damage. Our QC process protects your investment:
- Destructive Testing (The “Cut Check”): On large orders, we cut open a sample door to visually verify the thickness of the steel sheet or the density of the wood core.
- Paint Adhesion Test: Using a cross-hatch test to ensure the paint or veneer does not peel off over time.
- Size & Squareness: Measuring the diagonal lines to ensure the door slab is perfectly rectangular (not “diamond” shaped), which prevents jamming.
- Hardware Pre-assembly: We hang the door in its frame at the factory to verify the gap tolerance (2-3mm) and lock engagement.
- Corner Protection: Supervising the packaging to ensure strong plastic/cardboard corner guards are used to prevent impact damage during shipping.
Partner with HSY Sourcing: Open the Right Doors
Sourcing doors requires managing hundreds of SKUs, sizes, and opening directions (Left/Right/In/Out). HSY Sourcing acts as your project coordinator.
We review the Door Schedule (list of sizes and quantities), verify the “Rough Opening” dimensions with the factory, and manage the labeling for easy installation on site. We simplify your procurement, ensuring what arrives fits the building.
FAQ
Q: Do you supply doors as “Slabs only” or “Pre-hung”?
A: We can source both. For developers, we recommend Pre-hung (door + frame + hinges) to save labor costs on site. For wholesalers, Slabs allow for more efficient shipping.
Q: Can you handle custom fire-rated doors?
A: Yes. We work with factories that hold valid UL/WHI (Intertek) or BM TRADA certifications. We can verify the tag and label on each door.
Q: How many doors fit in a container?
A: It depends on the size and packaging. Typically, a 40HQ container holds about 200–250 sets of pre-hung security doors or 400–500 sets of interior door slabs. We optimize the loading plan for you.
