High-tensile structural steel plates — SAIL's renowned Sailma range (SA 350, SA 410, SA 450), boiler quality (IS 2002), and specialty wear-resistant grades. For bridges, heavy structures, pressure vessels, and defence.
Configure & Get Price →Sailma is a premium brand of high-tensile structural steel manufactured by SAIL (Steel Authority of India Limited). The name "Sailma" is derived from SAIL + MA (Micro Alloyed). These plates offer significantly higher yield strength than standard E250 MS plates while maintaining good weldability and toughness.

40–80% higher yield strength means thinner plates can carry the same load — saving weight and cost.
Low carbon equivalent ensures standard welding procedures work without pre-heating.
HI (High Impact) grades maintain toughness at sub-zero temperatures for cold-climate applications.
SAIL provides detailed MTCs with chemical composition and mechanical test results.
They are equivalent grades. Sailma 350 is SAIL's brand name for IS 2062 E350 grade steel. Other mills sell it as E350 (JSW), or use their own brand names.
Yes. Tiston is SAIL's abrasion-resistant plate. We stock Tiston 400 and Tiston 450 in common thicknesses (8–50mm). For other thicknesses, mill-direct procurement takes 2–3 weeks.
No. Sailma is a structural grade (IS 2062). For pressure vessels, you need IS 2002 or IS 2041 boiler quality plates which have specific requirements for elevated temperature service.
