ISA 200×100×10 is a standard unequal-leg angle in IS 808:1989. At 22.8 kg/m with a 200 mm long leg and 100 mm short leg, it is used for heavy structural bracing members in large-span industrial buildings, column-base gusset angles, crane-runway bracket connections, and primary truss chord angles in long-span roof structures.

Common Applications of ISA 200×100×10
ISA 200×100×10 is used for heavy structural bracing members in large-span industrial buildings, column-base gusset angles, crane-runway bracket connections, and primary truss chord angles in long-span roof structures. General steel merchants and angle stockists carry this size in IS 2062 E250 grade in 6 m and 12 m lengths. JSPL, SAIL, and RINL (Vizag Steel) all roll this designation to IS 808:1989 as standard stock.
Worked Example
A fabricator in Surat needs 4 primary truss chord bracing on a 50 m × 100 m warehouse using ISA 200×100×10, each 4000 mm long. Total length = 4 × 4.0 = 16.0 m. Weight = 16.0 × 22.8 = 364.8 kg. At ₹63,000 per tonne (Surat, May 2026), material cost is approximately ₹22,982 before cutting charges.
