HEA180 HEB180 S355NL/S355ML Steel Profile H beam
HEA steel flanges are thinner and lighter, suitable for applications requiring higher economy, such as lightweight structures or secondary load-bearing members. HEB steel flanges and webs are thicker, suitable for applications requiring higher load-bearing capacity and stiffness, such as columns for heavy bridges or high-rise buildings.
S355NL steel h column and S355ML structural h beam belong to the European standard EN 10025, which is usually used for structural steel, and represent the normalized (NL) and thermomechanical rolled (ML) treatments respectively. The strength grade of these materials is usually 355 MPa.
