EN S355JR UB305*102*28 305*102*33 H Beam Steel Structure

Chemical composition of S355JR steel h beam: carbon (C) content ≤0.22%, silicon (Si) content ≤0.55%, manganese (Mn) content ≤1.60%, phosphorus (P) content ≤0.025%, sulfur (S) content ≤0.025%.

Mechanical properties of S355JR h section steel: It is a low-alloy high-strength structural steel with a yield strength of 355MPa, a tensile strength between 470-630MPa, an elongation of about 22%, and good impact toughness at room temperature, which can meet the corresponding standard requirements such as 27 joules.

The specific size of 305*102*28 h-shaped steel: the actual size is 308.7mm×101.8mm×6mm×8.8mm, of which 308.7mm is the height of the steel, 101.8mm is the flange width, 6mm is the web thickness, 8.8mm is the flange thickness, and the weight per meter is about 28.2 kg.

Cross-sectional shape characteristics: UB type belongs to H-shaped steel with wide waist and narrow flange, which has good performance in bending resistance and is suitable for smaller load bearing conditions.
