High Quality SS400 H Section Galvanized Steel
Basic specifications and material properties
Name: SS400H steel (JIS G3101 standard), where "SS" means structural steel, "400" means the minimum tensile strength is 400 MPa, and "H" means H-section.
Size: Common specifications include 125×125×6.5×9 (flange width×web height×flange thickness×web thickness).
Material: Carbon structural steel with moderate carbon content (C: 0.16–0.22%) and controlled impurities (P, S≤0.050%).
Mechanical properties of SS400 carbon steel sections
Tensile strength: 370–510 MPa, meeting the minimum requirement of 400 MPa.
Yield strength: varies with thickness: ≥245 MPa (thickness ≤ 16 mm) ≥235 MPa (16–40 mm) ≥215 MPa (40–100 mm).
Elongation: ≥26%, ensuring ductility under stress.
Impact toughness: ≥27 J, suitable for dynamic loads.
Galvanizing process and advantages of SS400 hot-rolled steel sections
Coating method: hot-dip galvanizing after rolling to enhance corrosion resistance in outdoor or humid environments.
Advantages
Durability: The zinc layer prevents rust and extends service life;
Low maintenance: reduces the need for frequent repainting or treatment.
Physical and processing properties of SS400 H-beams
Weldability: Excellent compatibility with common welding techniques such as arc welding.
Cold workability: Easy to cut, bend or process without cracking.
Surface treatment: Smooth galvanized coating ensures beautiful and uniform protection.
Applications of SS400 galvanized steel sections
Construction: Structural frames, warehouses and industrial buildings.
Infrastructure: Bridges, transmission towers and offshore platforms (galvanized version).
Transportation: Vehicle chassis and ship components that require strength and corrosion resistance.
