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 200×200×18
ISA 200×200×18 is used for the most heavily loaded primary chord members in very large span industrial trusses, compound column sections under maximum axial load in major infrastructure frames, primary heavy wind bracing under extreme lateral loads, and major structural connection nodes in heavy industrial plants. Available from JSPL and Tata Steel.
Worked Example
A structural engineer in Delhi specifies ISA 200×200×18 for 4 primary chord members, each 6 m long, for a 55 m span very heavily loaded industrial crane truss. Total length = 4 × 6 = 24 m. Weight = 24 × 53.8 = 1,291.2 kg (1.291 tonnes). At ₹62,000 per tonne (Delhi, May 2026), material cost is approximately ₹80,054.
