H-Section Steel
Basic Definition
H-section steel is an efficient economic steel with an “H”-shaped cross-section, consisting of a web and symmetrical flanges, offering superior mechanical properties.
Hot-rolled H-section steel: HW200×200, HN300×150, HM400×200, etc.
Key Advantages
High Strength: Excellent resistance to bending and torsion, suitable for large-span structures Material Efficiency: Saves 15%-30% steel compared to I-beam Easy Processing: Standardized dimensions, convenient for welding/bolted connections
Main Applications
Building frames, bridge girders
Machinery bases, equipment supports
Energy equipment, ship structures
Why Choose H-Section Steel?
- High load-bearing capacity, efficient construction
- Cost-effective, environmentally friendly
