IS 4923 Pipes Industrial Applications

Hollow structural tubes, IS 4923, find use across four key sectors.

Construction & Building Structures

IS 4923 sections form the skeleton of steel-frame buildings, from roof trusses and columns to mezzanine floors.

Infrastructure & Bridge Construction

Structural steel tubes IS 4923 are specified for guardrails, pedestrian bridges, and highway gantries.

Industrial & Manufacturing Fabrication

Conveyor frames, machine guards, and storage racks use IS 4923 sections for simple bolting and welding.

Agricultural & Greenhouse Structures

Lightweight IS 4923 sections in YSt 210 serve greenhouse frames and poultry sheds. Galvanised finish adds outdoor corrosion protection.

IS 4923 Pipe Grades

IS 4923 defines 3 standard grades for hollow steel sections: YSt 210, YSt 240, and YSt 310.

IS 4923 YSt 210 Grade

YSt 210 is the basic grade in IS 4923, with a minimum yield strength of 210 MPa (like Fe 330). It suits fencing, small frames, and furniture where load demands are moderate.

IS 4923 YSt 240 Grade

IS 4923 YSt 240 is the most widely specified grade in Indian construction, at 240 MPa minimum yield strength (Fe 410). Frames, trusses, and columns are its core territory. Engineers default to YSt 240 unless loads call for YSt 310.

IS 4923 YSt 310 Grade

IS 4923 YSt 310 has the highest standard yield strength of 310 MPa (Fe 490). It is commonly used in high-rise buildings, bridges, and crane structures.
