Product Guide & Technical Article

Stainless Steel Sheets, Plates & Coils: A Complete Reference

Stainless steel flat products — sheets, plates, and coils — form the foundation of fabricated equipment across chemical, pharmaceutical, food processing, and architectural applications. Their versatility, corrosion resistance, and aesthetic appeal make them indispensable.

Sheet vs Plate vs Coil

Sheets are thin flat products (typically under 6mm thick) supplied in fixed lengths or coil form. Plates are thicker (6mm and above) used for structural and pressure vessel applications. Coils are continuous rolled strips used for high-volume fabrication and forming operations.

Grade Selection Guide

SS 304/304L — general purpose, excellent formability. SS 316/316L — superior chloride resistance for marine and chemical use. SS 321 — stabilized grade for elevated temperature service. SS 310 — high temperature oxidation resistance. Duplex 2205 — high strength with excellent corrosion resistance.

Surface Finishes

Available in 2B (mill finish, most common), No. 4 (brushed), No. 8 (mirror polish), BA (bright annealed), and HR (hot rolled) finishes depending on aesthetic and functional requirements.

Standards & Certifications

Supplied to ASTM A240, EN 10088, and IS 6911 standards. IBR (Indian Boiler Regulations) test certificates available for boiler quality plates. Mill test certificates provided with every supply.
