Sourcing Sheet Metal from China: A Practical Buyer Checklist
Eight checks for supplier review, drawing preparation and quotation comparison.
Confirm the supplier and certificate
Ask for the operating address, the quality certificate number and a copy that can be checked against the party named in your commercial documents. Steadfab's Suzhou factory holds ISO 9001:2015 certificate LBC22Q0197ROS.
Match the equipment to your part
Review bed length, forming capacity, welding resources and any machining needed after fabrication. For reference, Steadfab operates two 6-meter 12 kW fiber lasers, a tube laser, three 150-ton CNC press brakes, 25 welding stations and a gantry machining center.
Send a complete drawing package
Provide a 3D model when available, a dimensioned drawing, material and finish requirements, critical characteristics, quantity and the intended assembly context. Mark undecided items for engineering advice.
Look for real DFM questions
A useful review identifies unclear dimensions, difficult bends, weld access, hardware conflicts and finish-sensitive areas. A fast price without drawing questions is not the same as an engineering review.
Compare the same quotation scope
Make sure each quote covers the same drawing revision, quantity, finish, hardware, inspection expectations, packaging and delivery responsibility before comparing totals.
Approve a sample before production
A physical sample helps both sides confirm the drawing, assembly interfaces and finish expectations. Steadfab accepts sample orders from 1 piece.
Understand the finishing chain
Ask which finishing steps are completed in-house and how outside processes are checked. Steadfab completes high-temperature bake painting in-house; selected powder coating partners return parts for color, film-thickness and adhesion checks.
Keep one accountable owner
Choose a workflow where one named person owns open questions, drawing revisions and the handoff between processes. Steadfab provides direct engineer contact and one accountable project owner.
