RHS (Rectangular Hollow Section) and SHS (Square Hollow Section) Pipes

RHS (Rectangular Hollow Section) and SHS (Square Hollow Section) Pipes

RHS (Rectangular Hollow Section) and SHS (Square Hollow Section) pipes are structural steel tubes with hollow rectangular or square cross-sections, made from mild steel or high-strength variants for superior load-bearing in construction and fabrication.

RHS and SHS offer efficient, aesthetic alternatives to angle or I-beams, optimizing space and material use in modern structures.

Key Differences

Aspect

RHS (Rectangular)

SHS (Square)

Shape

Longer sides for directional strength (e.g., beams)

Equal sides for uniform strength (e.g., columns)

Strength

Higher bending resistance along longer axis

Balanced multi-directional load capacity

Properties

  • High strength-to-weight ratio: Lighter than solid sections yet torsion-resistant.
  • Versatile: Weldable, boltable; coated for corrosion protection.
  • Manufacturing: Cold-formed or hot-rolled from steel strips, to standards like IS 4923.

 

Applications

  • Construction: Frames, trusses, roofing, bridges, railings.
  • Industrial: Machinery supports, conveyor frames, storage racks.
  • Others: Fencing, Structural support, automotive chassis.
