S355JR Hot-Rolled Steel H Beam
The main chemical composition limits of S355JR H-beam columns are C≤0.22%, Si≤0.55%, Mn≤1.60%, P≤0.025%, S≤0.025%. Small amounts of other alloying elements can also be added to improve the performance of the steel. GNEE is available in a variety of sizes, such as HEA (European wide flange H-beam), HEB (European standard size H-beam) and HEM (European narrow flange H-beam). Common sizes include HE100A (100×96×5×8), HE120B (120×120×6.5×11), etc.
