Product Description:

WinscoMetal multi-grade BA surface cold rolled stainless steel coil covers 201, 304, 304L, 316 and 316L grades. Adopting professional cold rolling and bright annealing technology, the steel coil obtains ultra-smooth, mirror-bright BA surface without oxidation spots or uneven luster. With precise thickness tolerance, flat surface and stable mechanical performance, this cold rolled stainless steel coil supports custom slitting, cutting and forming. Suitable for architectural decoration, hardware stamping, kitchen equipment, electronic parts and industrial anti-corrosion applications, it is one of the most versatile decorative and industrial stainless steel coil materials.

Product Advantage:

• Premium BA Bright Annealed Surface: Uniform mirror-bright finish with high cleanliness, no black spots or scratches. No need for secondary polishing, saving processing cost and improving production efficiency.
• Complete Grade Coverage: 201 for cost-effective decoration; 304/304L for general anti-rust and sanitary use; 316/316L for coastal, saltwater and heavy corrosive environments.
• Superior Corrosion & Rust Resistance: High-purity chromium alloy structure effectively resists oxidation, moisture, acid and alkali corrosion, ensuring long-term stable service life in various environments.
• Excellent Processing Performance: Good ductility, toughness and weldability, suitable for deep drawing, bending, stamping, laser cutting and complex secondary processing.
• Stable Cold Rolled Performance: Cold rolling process improves tensile strength and surface flatness, with tighter size tolerance than hot rolled coils.
• Full Customization Support: Flexible custom thickness, width slitting and coil inner diameter to meet personalized industrial and decorative production needs.

FAQ

• Q: What is BA surface finish on stainless steel coil?
  A: BA (Bright Annealed) is a bright, smooth mirror surface formed by bright annealing after cold rolling. It features high gloss, no oxidation layer and clean surface, suitable for direct decorative use and secondary processing.
• Q: What is the difference between 201, 304 and 316 BA stainless steel coils?
  A: 201 is cost-effective for indoor decoration; 304/304L offers excellent general corrosion resistance for food and sanitary fields; 316/316L with molybdenum element is suitable for coastal, marine and heavy corrosive environments.
• Q: Are BA stainless steel coils easy to process?
  A: Yes. Cold rolled BA coils have good ductility and flatness, supporting bending, deep drawing, stamping, welding and laser cutting without surface damage.
• Q: What thickness and width can you customize?
  A: Standard thickness 0.15mm–3.0mm, width 10mm–1500mm. We provide professional precision slitting service for custom size requirements.
• Q: Does BA bright surface fade or scratch easily?
  A: The BA surface is formed by high-temperature bright annealing with stable metallic luster. It is scratch-resistant and not easy to fade under normal indoor and dry outdoor environments.
• Q: Is 304/316 BA stainless steel coil food safe?
  A: Yes. 304 and 316 grade BA stainless steel coils are non-toxic, hygienic and fully compliant with food-grade application standards for kitchen and food machinery use.
• Q: Can you provide MTC certificates and samples?
  A: Official mill test certificates are provided before delivery. Small free samples are available for surface and quality inspection, customers only bear shipping fees.
