Structural Steel — Angles, Tees, Beams, Channels, Flats & Bars(IS 2062:2011 · IS 808:2021)
Mechanical qualification of hot-rolled structural steel sections — angles, tees, beams, channels, flats and bars — per IS 2062:2011, verifying tensile, bend and impact properties against the specified grade (E165 to E450).
What is Structural Steel Section Mechanical Testing?
Hot-rolled angles, tees, beams, channels, flats and bars are the primary members of steel trusses, frames and fabricated structures. IS 2062:2011 (Hot Rolled Medium and High Tensile Structural Steel) governs their mechanical and chemical requirements across nine grades from E165 up to E450, while IS 808:2021 specifies the dimensions and sectional properties (weight, area, moment of inertia) used in structural design.
Global Lab verifies each section against its declared grade with a tensile test (yield strength, ultimate tensile strength, percentage elongation), a bend test to confirm ductility, and — where the grade or project specification calls for it — a Charpy V-notch impact test to verify toughness at the specified temperature. Section dimensions and sectional properties are cross-checked against IS 808:2021 to confirm the rolled section matches its nominal designation.

How the Structural Steel — Angles, Tees, Beams, Channels, Flats & Bars is Conducted
- 1
Section Sampling & Dimensional Check
A representative length is sampled from the delivered section and checked against IS 808:2021 nominal dimensions and sectional properties for the declared designation. - 2
Tensile Test Coupon Preparation
A standard tensile coupon is machined from the flange or web (away from rolled edges) per the applicable sampling location rules in IS 2062:2011. - 3
Tensile Testing
The coupon is loaded in a calibrated UTM to determine yield strength, ultimate tensile strength and percentage elongation, checked against the declared grade's minimum requirements. - 4
Bend Test
A separate coupon is cold-bent through the specified angle around a mandrel of prescribed diameter; the outer surface is inspected for cracking to confirm ductility. - 5
Impact Test (Where Specified) & Reporting
For grades or projects requiring toughness verification, Charpy V-notch impact testing is conducted at the specified test temperature; all results are compiled into a NABL-accredited report via Autovity QLMS.
