SS400 Galvanized Steel H Shape Beam
SS400 H-beams are typically produced by hot rolling, where the steel is heated above its recrystallization temperature and formed into an H-beam. After rolling, the steel beams are galvanized.
Galvanizing SS400 H-beams involves applying a layer of zinc to them to protect them from corrosion. The most common method is hot-dip galvanizing, where the steel is immersed in molten zinc at about 450°C (842°F). The process forms a metallurgically bonded zinc coating that acts as a sacrificial anode, protecting the steel underneath even if the coating is scratched. The zinc coating increases the durability and lifespan of the H-beam, especially when used outdoors or in wet environments.
When SS400 steel is formed into an H-beam and galvanized, it combines the inherent properties of the steel with enhanced corrosion resistance, making it suitable for a variety of demanding environments.
SS400 galvanized H-beams are available in a variety of sizes, typically to JIS standards.
Common sizes include:
Web height (H): 100 mm to 900 mm
Flange width (B): 50 mm to 300 mm
Web thickness (d): 5 mm to 20 mm
Flange thickness (t): 8 mm to 35 mm
Length: Standard lengths are 6, 9 or 12 meters, and GNEE can produce custom lengths. Galvanized coating thickness typically ranges from 50 to 150 micrometers (µm), depending on the application and environmental conditions.
Comparison with other standards
SS400 is often compared to equivalent grades in other standards:
China (GB): Q235B (similar tensile strength and composition)
USA (ASTM): A36 or A283 Grade D
Europe (EN): S275 Although these equivalent materials have similar properties, there may be slight differences in chemical composition or mechanical requirements depending on the standard.
