Winsco Metal is a group-owned stainless steel sheet and coil manufacturer. Our 201,304,316 stainless sheets, including 2B, hairline, mirror, embossed and PVD color decorative plates, are produced according to widely adopted international standards with complete quality certifications.
ASTM A240 is our primary standard. It defines chemical composition, mechanical properties, dimensional tolerances and test requirements for stainless steel sheets and plates, widely accepted across North America, Middle East and many global construction projects. We can also manufacture to other regional standards upon request: EN 10088 for European clients, JIS G4304 for Japanese specifications and GB/T3280 for Chinese standard.
Our factory holds ISO 9001 quality management system certification, ensuring standardized production and full-process quality control from raw material incoming inspection to finished product packaging. Every batch of stainless steel sheets is supplied with MTC Mill Test Certificate (EN10204 3.1). This document records heat number, chemical composition, tensile strength, hardness and elongation data for project review and customs clearance.
We support independent third-party inspection. SGS and TUV are both accepted. Their inspectors can come to our factory to take samples, check surface appearance and perform laboratory tests before shipment. This is ideal for high-end elevator panels, building facade and coastal decoration projects with strict compliance requirements.
For special PVD color stainless steel sheets, we implement extra coating adhesion and color fastness tests to ensure scratch resistance and long-lasting color stability. Our QC team performs spectrum analysis on raw coils and continuously monitors thickness, flatness and surface quality during production. Any defective plates will be sorted out and rejected.
As a group factory, we offer direct factory pricing, stable supply and reasonable lead time. Our technical team will match the correct standard and required documents based on your target market.
