Dimensions and properties as per IS 808:1989 (Reaffirmed 2001). Mass tolerance: ±3% per piece as per IS 808. u–u is the major principal axis at 45° to both legs; v–v is the minor principal axis. Zvv is not published in IS 808:1989 for angle sections.
Common Applications of ISA 110×110×10
ISA 110×110×10 is used for primary truss chord members in 22–28 m span structures, back-to-back built-up compound columns, heavy primary wind bracing members, and large bolted gusset plate connections. Stocked by JSPL, Tata Steel, and SAIL in IS 2062 E250 grade.
Worked Example
A structural engineer in Ahmedabad specifies ISA 110×110×10 for 10 bottom chord members, each 6 m long, for a 26 m span lattice girder in a large factory. Total length = 10 × 6 = 60 m. Weight = 60 × 16.5 = 990 kg (0.990 tonnes). At ₹62,000 per tonne (Ahmedabad, May 2026), material cost is approximately ₹61,380.
