BS EN 10210 for Hot Finished Structural Hollow Sections

Standard Overview:
EN 10210 is a European harmonized standard for hot-formed structural hollow sections, including round, square and rectangular sections, both welded and seamless. It consists of two main parts: EN 10210-1 (technical requirements) and EN 10210-2 (dimensional specifications)

Main Material:
Non-alloy and fine-grained steels are available. Steel grade range: S235, S275, S355 and other different strength grades

Scope of Application:

Steel frames for building structures
Industrial equipment manufacturing
Infrastructure engineering (such as bridges, and towers)
Offshore engineering structures
Structural parts that need to withstand static or dynamic loads
