Winsco Metal is a group-owned manufacturer of stainless steel sheets and coils. Our plates including 201,304 and 316 grades with 2B, No.4 hairline, 8K mirror, embossed and PVD colored finishes strictly follow global recognized standards, supported by complete quality certification documents for export projects.
Our core standard for stainless steel sheets is ASTM A240, which specifies chemical composition, mechanical performance, dimensional tolerance and test requirements for stainless steel sheet, plate and strip for general construction and pressure vessel applications. We can also produce according to EN 10088, JIS G4304 or GB/T3280 to meet different regional market requirements for Europe, Asia and Latin America.
Our factory holds ISO9001 quality management system certification, which standardizes all production and QC workflows from raw coil incoming inspection to finished plate packing. Every batch can issue MTC Mill Test Certificates (EN10204 3.1) recording heat number, chemical spectrum analysis, tensile strength, hardness and elongation data, for project approval and customs clearance.
We fully welcome independent third-party inspection. SGS and TUV inspectors can visit our factory for on-site sampling, surface checking and lab testing before shipment. This is especially valuable for high-end facade, elevator and coastal decoration projects with strict compliance requirements.
During manufacturing, our QC team runs spectrum testing for raw coils, monitors thickness, flatness and surface quality during rolling and surface treatment. For PVD color stainless sheets, we carry out extra adhesion and color fastness testing to guarantee stable decorative effect. Non-conforming materials will be rejected before packing.
As group factory, we maintain stable production capacity, direct factory price and controllable lead time. Our technical team will select the correct standard and supporting documents matching your target market.
Share your sheet specs and required certification requirements. Winsco Metal group factory will produce qualified stainless steel sheets and provide full certification packages for your global orders.
