Why Steadfab

Three Unfair Advantages

What separates us from the typical China sheet metal shop.

01
Color-Accurate Finishing
High-temperature bake painting runs in-house. Powder coating runs through audited partner lines we have worked with for years — and every part comes back through our QC for RAL match, film thickness and adhesion before it ships. One accountable supplier either way.
02
2-Day RFQ Turnaround
Drawings in by 17:00 GMT+8 get a named-engineer reply with DFM notes within 2 business days. No auto-quote bots — pricing is engineer-validated, every time.
03
Vetted Sub-Supplier Network
A curated Yangtze Delta cluster covers casting, stamping and specialty plating beyond our own walls — one PO, one project engineer, full chain accountability. Laser tube cutting and gantry machining stay in-house.
