High-tolerance, surface-consistent stainless steel coils — certified for food-grade, marine, and industrial applications. Fully traceable, mill-tested, and globally compliant.
Stainless steel cold rolled coils deliver exceptional dimensional accuracy, superior surface finish, and consistent mechanical properties — critical for deep drawing, precision stamping, and high-end fabrication. Manufactured under strict ISO 9001 and ASTM A240 / EN 10088-2 standards, each coil undergoes full-thickness tensile testing, intergranular corrosion evaluation (ASTM A262 Practice E), and 100% surface inspection.
Ideal for buyers requiring zero-defect material in regulated industries — from FDA-compliant food processing lines to offshore marine platforms and medical device OEMs. All coils are supplied with mill test reports (MTRs), heat numbers, and full chemical & mechanical certification.
2B/BA/No.4 finishes meet Ra ≤ 0.15 μm tolerance across full coil width — verified via laser profilometry per ISO 4287.
304 & 316 grades comply with FDA 21 CFR §178.3710, EC 1935/2004, and EU 10/2011 — fully documented for sanitary equipment manufacturing.
Each coil carries a unique heat number linked to full MTRs — including chemistry (ICP-OES), tensile strength (≥520 MPa), elongation (≥40%), and bend test results.
Tanks, conveyors, hoppers, and filler nozzles — leveraging 304’s non-reactive surface and cleanability.
Pumps, valves, railings, and instrumentation housings — where 316L resists chloride-induced pitting.
Surgical trays, sterilization containers, and diagnostic enclosures — meeting ISO 13485 and biocompatibility requirements.
Elevator panels, façade systems, and interior trim — using No.4/HL or BA finishes for aesthetic durability.
