Reliable Window and Door Hardware Suppliers – China Factory Direct
Meta Title: Global Sourcing for Quality Window and Door Hardware – Trusted Chinese Supplier | TJJ TRADE
If you are an import manager, brand owner, wholesaler, or sourcing agent looking for window and door hardware suppliers that combine factory-direct pricing, rigorous quality assurance, and full OEM/ODM design support, you have found the right partner. Shijiazhuang TJJ TRADE CO., LTD. has operated its own foundry for over 20 years, delivering cast iron and wrought iron window and door hardware to North America, South America, Europe, and Africa. Our integrated supply chain in Hebei, China, ensures fast lead times, flexible MOQs, and compliance with international standards – without sacrificing the craftsmanship that modern architectural projects demand.
TJJ’s 20+ year old foundry – the first casting factory in China, equipped with experienced workers and modern management.
The Challenges of Sourcing Window and Door Hardware
Buyers in the USA and other English-speaking markets often struggle with:
- Inconsistent quality – hardware that fails after a few months due to poor casting or weak hinges.
- Long, unpredictable lead times – supply chain disruptions delay entire construction projects.
- Communication gaps – misunderstandings about specs, packaging, or compliance documents.
- Hidden costs – unexpected tariffs, labeling mistakes, or rework fees.
As a window and door hardware supplier with decades of foundry experience, TJJ addresses these pain points through vertical integration and a customer-first approach that treats each order as a partnership.
Why TJJ Stands Out Among Window and Door Hardware Suppliers
🔧 Full Customization (OEM/ODM)
We design and produce hardware to your exact drawings or samples. From decorative handles to heavy-duty storm door hinges, our engineering team works with you to adjust finishes, dimensions, and materials (cast iron, wrought iron, or steel). MOQ is flexible – start with as few as 100 pieces per SKU for OEM orders.
In-house casting and finishing – quality control from raw material to final packaging.
Sample room – hundreds of tested designs ready for your review.
✅ Quality Assurance & Compliance
Every batch undergoes strict checks: dimensional accuracy, salt spray testing, and load-bearing verification. We comply with ISO 9001:2025 standards (certified by SGS) and meet requirements for CE (construction products regulation), RoHS, and REACH when specified. For US projects, hardware can be produced to ANSI/BHMA grades. (“Please refer to the actual order confirmation for applicable certifications.)
🚚 Fast Lead Time & Reliable Delivery
As a factory that owns its foundry, we control scheduling. Typical lead time for standard designs is 25–35 days after deposit. For repeat orders, we can reduce to 20 days. We ship via FOB Tianjin or CIF to major US ports (Los Angeles, New York). Express air freight available for urgent samples. Packaging is designed to prevent damage – each piece individually wrapped, cartons strapped, and pallets shrink-wrapped.

Proven in the Field – Real Applications
Our window and door hardware is used in residential, commercial, and historical restoration projects across the US. Common configurations:
- Storm door hinges – heavy-duty cast iron, powder-coated black or bronze.
- Decorative casement window stays – wrought iron with traditional scrollwork.
- Lever handles for patio doors – strong, rust-resistant, with key lock options.
- Gate hinges and latches – matching sets for ornamental iron fences.
In a 2025 project for a Florida housing development, we supplied 12,000 pieces of custom window stays within 28 days, exceeding the client’s lead time by 7 days. All hardware passed ASTM B117 salt spray testing (96 hours). Data from actual orders; results may vary. Refer to order confirmation.)
What Our Buyers Say
David M. – Import Manager, Texas Builders Supply
"We switched to TJJ after repeated quality issues with our previous supplier. Their hardware is heavier, the finish is uniform, and they actually answer technical questions. Lead times are consistent – we now average 30 days door-to-door."
Laura K. – Brand Owner, Heritage Hardware Co.
"TJJ’s OEM service is excellent. They copied our antique handle design perfectly and even suggested a stronger alloy. The MOQ was lower than expected – only 150 pieces for our test run. We are now launching a full line."
James R. – Sourcing Agent, Architectural Ornaments Inc.
"I have worked with multiple suppliers in China, and TJJ stands out in communication. Sindy responds within hours, and they send real photos of production. We have shipped 8 containers without a single complaint from our customers."
Elena P. – Wholesaler, Midwest Fence & Gate Supply
"The quality of their ornamental iron hardware is perfect for our high-end residential projects. The powder coating lasts through Midwest winters. We now buy all our hinges and handle sets from TJJ."
Alan T. – Project Manager, Coastal Development Group
"TJJ helped us meet a tight deadline for a 500-unit apartment complex. They fast-tracked our order for 3,000 window stays and delivered in 22 days. The packaging was superior – zero damage."
Samuel L. – Brand Owner, Classic Ironworks
"As a small business, I appreciate that TJJ accepts smaller MOQs for custom designs. Their design team helped me create a unique handle collection that is now my bestseller. Highly recommend for OEM partnerships."
