Cold rolled and hot rolled coils with thickness from 0.2–6.0 mm and consistent width control. Bright annealed and precision-slitted options ensure stable quality across grades 304, 316L, 430, and 201.
Widely used in automotive trim, appliances, construction, and cable armoring. Finishes like 2B, BA, and HL combine durability with decorative appeal, supported by protective film packaging.
Each batch is verified with spectrometer testing and supplied with Mill Test Certificates (EN 10204 3.1). Compliance with ASTM, EN, JIS, and GB/T standards ensures reliable performance and global acceptance.
