A stainless steel coil is a rolled strip of stainless steel, made by hot or cold rolling, available in grades like 304 and 316L for industrial and decorative use.
What is the difference between cold rolled and hot rolled stainless steel coils?
Cold rolled coils have a smoother surface (2B/BA) and tighter tolerances, while hot rolled coils are thicker and used in structural or high-temperature applications.
What coil ID/OD is available?
Standard IDs are 508 mm and 610 mm; ODs and weights can be customized.
Which surface should I choose—2B, BA, or HL?
2B is for general use, BA for decorative/mirror applications, HL for brushed decorative finishes.
