The Champak Steel YST 310 MS RHS - (200 x 100 x 3 mm) - 6 mtr Length is a structurally certified Rectangular Hollow Section from Champak Steel in YST 310 mild steel, manufactured to IS 4923:2017 (Hollow Steel Sections for Structural Use). This 200 mm × 100 mm × 3 mm section in 6 m standard lengths delivers high major-axis bending capacity and excellent torsional rigidity — perfectly suited for heavy-duty structural, high-load, and long-span applications. With minimum yield of 310 MPa and tensile of 450 MPa, it supports efficient structural design with reduced member sizes and optimised steel weight for long-span applications.
