Q1: Can these black sofa hinges be used for both headrests and armrests?

A: Absolutely. BLS Hardware provides DXF, DWG, and STEP 3D files for furniture engineers to integrate the mechanism directly into their sofa frame CAD models before sampling.

Q3: What surface treatment is applied to prevent rust inside the sofa?
A: We apply a durable black electrophoresis or powder coating that passes rigorous salt-spray testing, ensuring the metal hardware remains rust-free and aesthetically pleasing throughout the sofa’s lifespan.
