W14x311 W14x342 W14x455 Wide flange H-beam
Common materials for W14x311 W14x342 h type steel beam are A36, A572GR50, A992, etc. Taking A992 material as an example, its chemical composition includes carbon content of 0.27% - 0.35%, silicon content of 0.93% - 1.20%, manganese content of 0.80% - 1.10%, phosphorus and sulfur content of no more than 0.025%, etc. In terms of mechanical properties, the tensile strength is not less than 560MPa, the yield strength is not less than 460MPa, the elongation is not less than 10%, the cross-sectional shrinkage is not less than 45%, and the impact energy is not less than 39J.
Features of W14x311 W14x342 h type beam
Excellent cross-sectional performance: The cross-sectional shape of H-shaped steel is economical and reasonable, and the mechanical properties are good. Compared with ordinary I-beam, it has the advantages of large cross-sectional modulus, light weight, and metal saving, which can reduce the building structure by 30%-40%.
Convenient construction: Because the inner and outer sides of the legs are parallel and the leg ends are right angles, when assembling and combining into components, the welding and riveting workload can be saved by 25%.
The mechanical properties of W14x455 h steel profile depend on the steel grade used, and common materials include ASTM A36 structural steel beam, A992 steel beam or A572, etc. W14x455 h section steel is usually produced by hot rolling process, where the steel billet is rolled at high temperature to ensure material uniformity and surface quality. Compared with welded H-shaped steel, hot rolled steel has lower residual stress and better structural stability.
Advantages of W14x455 steel h profile
High load-bearing capacity: reasonable cross-sectional design and excellent strength-to-weight ratio.
Construction efficiency: easy to machine, connect and install, suitable for all-weather construction.
Structural stability: strong resistance to vibration and impact, suitable for extreme environments.
Space saving: compared with concrete structures, the small cross-sectional area can increase the effective use area.
