Stainless Steel Sheet (Cold Rolled) – Grade 304 / 304L / 316L / 430, 2B / BA / No.4 / HL / 8K Mirror Finish, 0.3-6.0mm Thick for Architecture, Kitchen & Industry
Product Overview
Our cold-rolled stainless steel sheets are manufactured from high-quality austenitic (300 series) and ferritic (400 series) grades, offering excellent corrosion resistance, formability, and aesthetic appeal. Available in thicknesses from 0.3mm to 6.0mm and widths up to 2500mm, these sheets are produced to international standards including ASTM A240, JIS G4305, EN 10088, and GB/T 3280. With a wide selection of surface finishes—from standard 2B to mirror-like 8K—our stainless steel sheets serve diverse industries including construction, kitchenware, automotive, medical equipment, and chemical processing.
Specification Spotlight: Surface Finish Options
Stainless steel sheet surface finish directly impacts its appearance, corrosion resistance, and maintenance requirements. We offer the following standard finishes:
| Finish | Description | Best For |
|---|---|---|
| 2B | Cold-rolled, annealed, pickled, and lightly rolled with polished rolls – smooth, semi-reflective matte finish | General industrial, kitchen equipment, food processing |
| BA (Bright Annealed) | Bright annealed in controlled atmosphere – highly reflective, mirror-like surface | Decorative panels, elevator interiors, appliances |
| No.4 | Brushed/satin finish – mechanically polished with 150-180 grit abrasives, fine directional lines | Architectural cladding, elevators, commercial kitchens |
| HL (Hairline) | Long, continuous polishing lines – linear brushed texture | Decorative trims, building facades |
| 8K Mirror | Super mirror finish – highest reflectivity, image-clear | High-end decoration, luxury elevators, showcases |
| No.1 | Hot-rolled, annealed, pickled – dull, rough surface | Chemical equipment, industrial tanks |
Core Advantages
Superior Corrosion Resistance – Austenitic grades (304/316L) contain 18% chromium and 8% nickel, forming a passive oxide layer that resists rust, staining, and chemical attack. 316L adds 2-3% molybdenum for enhanced resistance to chlorides and pitting.
Excellent Formability – High ductility allows deep drawing, bending, and stamping without cracking. 304 offers exceptional deep-drawability for complex shapes.
Wide Grade Selection – From cost-effective 430 ferritic (ideal for indoor applications) to marine-grade 316L (for coastal and chemical environments), we match the right material to your application.
Aesthetic Versatility – Choose from matte 2B to mirror 8K, brushed No.4 to hairline HL – each finish delivers a distinct visual effect.
Hygienic & Easy to Clean – Non-porous surface resists bacterial growth and is easily sanitized, making it ideal for food and medical applications.
