EN 10219 S235JRH Square Hollow Section (SHS) is a cold-formed welded structural steel tube manufactured according to the European standard EN 10219. As one of the most widely used structural steel grades in Europe, S235JRH provides an excellent combination of strength, weldability, and cost efficiency for general construction and engineering applications.
Thanks to its reliable mechanical properties and easy fabrication, S235JRH square hollow sections are widely used in steel structures, industrial buildings, transportation equipment, machinery manufacturing, and renewable energy projects.
EN 10219 covers cold-formed welded structural hollow sections manufactured from non-alloy and fine-grain steels. Unlike EN 10210 hot-finished hollow sections, EN 10219 products are produced through cold-forming and welding processes.
The designation S235JRH means:
S = Structural Steel
235 = Minimum yield strength of 235 MPa
JR = Impact energy ≥ 27 J at +20°C
H = Hollow Section
This grade is primarily designed for structural applications operating under normal temperature conditions.
