Model identification: UB 406×178×67 (wing width 406mm, waist height 178mm, wing thickness 67mm)
Cross-sectional area: about 85.5 cm², theoretical weight per meter is about 67 kg/m
h beam section material comparison
S275JR h shaped steel: yield strength ≥275MPa, tensile strength 490-660MPa, carbon content 0.21-0.27%, suitable for medium load structures (such as industrial plants, equipment brackets).
S355JR h beam structure: yield strength ≥355MPa, tensile strength 590-760MPa, carbon content 0.28-0.34%, suitable for high load scenarios (such as bridge main beams, heavy machinery structures).
Both materials contain alloy elements such as manganese and silicon, and the sulfur and phosphorus impurity content is ≤0.04%, with good weldability and low temperature toughness.
GNEE production process and standards
Production standards: Implementation of British standards (BS EN 10025), hot rolling forming process, tolerances meet EN 10034 standards.
Surface treatment: natural oxide layer after hot rolling, optional sandblasting or galvanizing for corrosion protection.
