Product Spotlights
Product Definition – Stainless Steel Strip
Stainless steel strip is a thin, flat-rolled coil product manufactured from stainless steel slabs through hot rolling and precision cold rolling. It is characterized by tight thickness tolerances, excellent surface quality, and consistent mechanical properties. Strips are supplied in coil form, with slit edges or mill edges, and can be further processed into formed parts, spring components, or welded tubes.
Common grades include 301, 304, 316L, 430, and 201, with tempers ranging from annealed to full hard (1/4H, 1/2H, 3/4H, H). Surface finishes include 2B, BA, No.4, HL, and mirror.
Typical applications:
Automotive parts (hose clamps, gaskets, seat belt springs)
Electronic components (shielding, battery connectors, spring contacts)
Medical devices (surgical blades, guidewires, orthodontic wires)
Industrial (conveyor belts, hose clamps, spring washers, knife blades)
Construction (trim, flashing, roofing details)
We supply stainless steel strips with EN 10204 3.1 mill certificates, precision slitting (tolerance ±0.05mm), and flexible MOQ.
