S355JR S355J0 UB 533x210x122 Structural Section Beam

S355JR h beam section and S355J0 h steel profile are non-alloy structural steels produced according to European standard EN 10025-2 for general structural and engineering purposes.

Impact properties of S355JR S355J0 steel beam
S355JR h beam: Charpy V-notch impact test at +20°C requires a minimum impact energy of 27J.
S355J0 steel h beam: The same impact test at 0°C also requires a minimum impact energy of 27J; S355J0 is more suitable for applications where lower temperatures may be encountered.

UB 533x210x122 H-section steel has a large cross-sectional size and a relatively high unit weight, which makes it suitable for structural applications that require high load-bearing capacity and good rigidity. This type of steel is often used in building frames, bridge construction and other large infrastructure projects as a primary load-bearing member or part of the supporting structure.
