The RD-HL-01 hinge lug is a key rotating component for connecting doors to container bodies, storage cabinets, and industrial doors. Made of Q235B carbon steel, thickness T8 (8mm), weight only 0.05kg, with cold galvanized surface. It is not a common hinge – it is a standardized accessory for frequent opening and light-load connections.
User Problem: Rust, sticking rotation, or weld failure at the hinge point of container/equipment doors – causing door sagging or inability to close tightly.
Cause Explanation:
· Ordinary iron hinges without anti-corrosion treatment rust quickly in humid environments
· Insufficient material strength (e.g., A3 steel or cold-rolled sheet) leads to deformation after repeated opening
· Dimensional mismatch (thickness or hole position deviation) causes uneven stress after installation
---
The RD-HL-01 offers a material + anti-corrosion + precision solution:
· Q235B carbon steel, yield strength ≥235MPa, good weldability and toughness
· T8 thickness (8mm) – more resistant to deformation than common 5mm hinges
· Cold galvanized surface, evenly covering edges, providing basic rust protection (indoor or short-term outdoor use)
Conclusion: Choose RD-HL-01 for smooth door rotation, longer rust resistance, and hassle-free installation.
