Cold Rolled Stainless Steel Coil (2B Finish)
Cold Rolled Stainless Steel Coil (2B Finish)
Cold Rolled Stainless Steel Coil (2B Finish) offers a smooth, clean, and matte-grey surface produced through cold rolling, annealing, and pickling. It provides tighter thickness tolerances and better surface quality compared to hot rolled coils. Ideal for deep drawing and general fabrication.
Popular Grades:
- Stainless 304 / 304L – Standard food-grade stainless steel. Excellent corrosion resistance, widely used for kitchen equipment and appliances.
- Stainless 316 / 316L – High corrosion resistance with Molybdenum content. Suitable for chemical, medical, and marine applications.
- Stainless 430 – Ferritic grade (Magnetic). Cost-effective, used for interior decoration and appliances.
Specifications:
- Thickness: 0.4 mm – 3.0 mm (Standard Stock)
- Width: 1219 mm (4 ft), 1524 mm (5 ft) or Custom Slitting
- Surface: 2B (Smooth, Matte, Reflective)
Applications:
- Kitchen sinks, cutlery, and catering equipment
- Electrical appliances (Refrigerators, Washing machines)
- Architectural panels and elevators
- Automotive parts and electronic components

Why Choose Cold Rolled Stainless Steel Coil (2B)?
Cold Rolled Stainless Steel is processed at room temperature, allowing for precise control over thickness and dimensions. This results in a material that is thinner, smoother, and stronger than hot-rolled options.
Advantages of 2B Finish
The 2B Finish is the most widely used stainless steel surface finish. It is smooth, slightly reflective, and cost-effective. It serves as an excellent base for further polishing (such as Hairline or Mirror finish) or painting.
Benefits of Purchasing Coil:
- Automation Ready: Ideal for continuous feeding into stamping or roll-forming machines, increasing production efficiency.
- Minimized Waste: Coils can be cut to the exact length needed for your product, reducing off-cuts and scrap.
