FAQ

We compile frequently asked questions from customers and provide clear answers covering factory strength, custom production, MOQ, lead time, quality assurance and after-sales support, helping buyers make informed sourcing decisions.

A:

Yes. We work from customer drawings and provide OEM/ODM service, incoming-material processing and component machining. Materials include stainless steel, aluminum, electrolytic sheet, hot-rolled, galvanized and cold-rolled steel, with powder coating, galvanizing, sand blasting, brushing and polishing available.

A:

Cutting, bending, riveting, welding (MIG, TIG and laser), rust prevention and coating all run under one roof, so tolerance and lead time stay under our own control instead of being split across subcontractors.

A:

Material certificates, first-article inspection reports, dimensional inspection records and coating thickness records for galvanizing and powder coating, plus shipping inspection records for batch orders. Third-party testing can be arranged on request.
