Stainless Steel Sheets / Plates
What are Stainless Steel Sheets & Plates?
Stainless Steel Sheets and Plates are flat-rolled steel products made from corrosion-resistant stainless alloys, available in a wide range of thicknesses and finishes. While sheets are generally thinner (below 6 mm), plates are thicker and used in heavy-duty structural or industrial applications.
Asiad Steel Industries is a trusted manufacturer and exporter of premium-grade stainless steel sheets and plates in 304, 316, 310, 321, and various duplex alloys.
