BA Bright Annealed Stainless Steel Coil
BA (Bright Annealed, marked as 2R in EN 10088‑2) stainless steel coil is premium cold‑rolled stainless steel coil annealed in oxygen‑free protective atmosphere without pickling. It delivers an ultra‑smooth, bright, highly reflective mill surface, brighter than standard 2B finish. As base material for further polishing into 8K mirror, HL hairline and colored decorative surfaces, it features lower surface roughness, cleaner surface, fewer defects and superior cleanability, ideal for sanitary and food‑grade applications. A protective PE film is laminated to prevent scratches during slitting, stamping, bending and shipment.

Hot rolled stainless steel coil is produced by high‑temperature slab rolling, followed by annealing and pickling, known as No.1 finish. It is the heavy‑gauge base material widely used in heavy industrial fabrication, pressure equipment and pipe production, different from thin‑gauge 2B cold‑rolled stainless steel coil. The No.1 surface is a dull, non‑reflective pickled finish with stable mechanical property, high‑temperature resistance and excellent corrosion resistance. It is the ideal raw material for further cutting, bending, forging, welding and deep processing.
8K Mirror (No.8) stainless steel coil is high‑grade polished cold‑rolled stainless steel coil, manufactured by multi‑stage fine grinding and buffing on 2B / BA base material to achieve glass‑like specular reflection, clear image reflection, low haze and uniform gloss across the whole coil. As the premium decorative stainless steel finish, it is widely selected by fabricators, elevator factories, architectural contractors and signage makers. Unlike matte 2B, HL hairline or No.1 hot‑rolled surfaces, the 8K mirror finish features an ultra‑smooth surface and excellent decorative performance while retaining the original corrosion resistance and ductility. PVD colored mirror coil (gold, rose gold, black titanium, champagne) is available on request.
HL hairline stainless steel coil, also known as long‑line brushed stainless steel coil, is processed from premium 2B or BA cold‑rolled substrate with continuous abrasive belt grinding to create fine, uniform, straight hair‑like linear grain across the whole coil. Compared with No.4 short‑brush finish, HL features longer, smoother and more elegant streaks, widely adopted for mid‑to‑high‑end architectural and elevator decoration projects. The hairline surface effectively hides minor scratches and fingerprints for easier daily maintenance than 8K mirror finish. PVD colored HL coil (gold, rose gold, black titanium, champagne) is available upon request.
