sus BA 430 Cold Rolled Stainless Steel Coil metal roof sheet
Stainless Steel Coil
The properties of stainless steel are corrosion resistance, high ductility, attractive appearance and low maintenance.
Stainless steel contains chromium which provides the properties of corrosion resistance at high temperatures. Stainless steel can withstand corrosive or chemical environments due to its smooth surface. Stainless steel products are safe for long-term use with excellent resistance of corrosion fatigue.
