EN 10210 S235JRH Pipes – Technical Overview
Introduction to EN 10210 S235JRH Pipes
EN 10210 S235JRH Pipes are hot-finished structural hollow sections made from non-alloy steel, designed for mechanical, structural, and constructional applications. These pipes conform to the EN 10210-1 and EN 10210-2 European standards, which define technical delivery requirements for hot-finished hollow sections of non-alloy and fine-grain structural steels
The designation S235JRH breaks down as follows:
● S – Structural steel
● 235 – Minimum yield strength of 235 MPa
● JR – Impact tested at +20°C
● H – Hollow section
These pipes are known for their excellent weldability, dimensional accuracy, and strength, making them ideal for load-bearing and pressure-bearing applications in construction, mechanical systems, and fabrication industries
