When you source door hinges for aluminium doors for your distribution or manufacturing business, you need a partner who guarantees consistency, load capacity, and corrosion resistance. As a foundry and export company with over two decades of direct experience, we engineer hinges that match ANSI/BHMA Grade 1 and Grade 2 requirements, with full OEM/ODM flexibility. Whether you need stainless steel 304 hinges for coastal commercial projects or custom-finish steel hinges for residential aluminium door lines, our factory delivers MOQ as low as 500 pieces, 15–25 days lead time, and rigorous quality control backed by ISO 9001 principles.

Why Standard Hinges Fail on Aluminium Doors – and How We Solve It

Aluminium doors are lightweight yet strong, but standard steel hinges can cause galvanic corrosion, while poorly cast hinges often suffer from cracking or misalignment. Many importers complain about inconsistent thickness, wrong screw hole patterns, and short warranty periods. Our solution is simple: a factory that controls the entire casting and machining process.

• Pain Point: Corrosion between steel hinge and aluminium frame.
  Our Solution: Offer 304/316 stainless steel, zinc-plated steel, or powder-coated options with anti-corrosion treatments. Select materials per your environment (interior/exterior, coastal/industrial).
• Pain Point: Hinges that sag under heavy door weight.
  Our Solution: Precision casting with wall thickness tolerance ±0.2 mm, and load capacity tested up to 150 lbs per pair (Grade 2) and 250 lbs (Grade 1) for standard commercial doors.
• Pain Point: Mismatched holes and screw patterns.
  Our Solution: Full OEM/ODM – we reproduce your template or design using CAD, then CNC-machined jigs for zero variation across production lots.

TJJ’s 20,000 m² foundry – one of the first casting factories in China, producing hinges for global brands.

Why American Importers Trust TJJ for Door Hinges

What Our Customers Say

Gary Thompson

Import Manager, West Coast Door Supply (California)

"We switched to TJJ for our aluminium door hinge line after persistent quality issues with another Chinese supplier. Their hinges have consistent countersink depth and perfect screw alignment. The 304 stainless batch we ordered passed 72-hour salt spray without a speck of rust. Lead times have been reliable – 18 days average. They understand the US market."

Laura Hernandez

Brand Owner, Modern Entry Concepts (Texas)

"I needed a custom hinge shape for our new aluminium pivot door. TJJ worked from my CAD file and had samples in 10 days. The MOQ was only 800 pieces – much lower than other foundries. Communication was clear despite the time difference. The final product looks premium; our clients love the smooth movement."

Robert Chen

Sourcing Agent, Global Hardware Sourcing (Florida)

"I’ve visited TJJ’s factory twice. Their casting process is well-controlled, and they have separate QC storage for export. I’ve sourced over 15,000 pairs of hinges for aluminium doors from them in the past two years – reject rate below 0.3%. Their pricing is competitive even with the 25% tariff; they help with paperwork."

Michael Ortega

Purchasing Manager, AA Door & Frame (New York)

"We needed a heavy-duty hinge that could hold 200 lbs on our commercial aluminium doors. TJJ provided a Grade 1 hinge with 5 knuckles and ball bearings. After 6 months of use in a high-traffic office, no sagging, no noise. Their after-sales is responsive – we had one small finish issue and they shipped replacements immediately."
