American wide flange beam W21X147 hot rolled

Model definition

The "W" in W21x147 h beam section stands for wide flange profile, "21" stands for the nominal section height of 21 inches (about 533mm), and "147" stands for the theoretical weight of 147 pounds per foot (about 219kg/m).

W21x147 steel h profile specific dimensions

Section height: 533mm (21 inches) ‌

Flange width: about 216mm (slightly different for different manufacturers) ‌

Web thickness ≥ 25mm, flange thickness ≥ 30mm (subject to the manufacturer's technical manual).

Execution standard: Meets ASTM A572 Gr.50 and A992 h beam material standards, with high strength and welding performance, suitable for dynamic load scenarios.

Mechanical properties‌: yield strength ≥ 345MPa (50ksi), tensile strength ≥ 450MPa (65ksi), elongation ≥ 18%, carbon equivalent (CE) ≤ 0.45%, suitable for high stress environment.

‌High-rise buildings‌: As a large-span main beam or column, it is used for main load-bearing structures such as commercial complexes and industrial plants.

Bridge engineering‌: Suitable for scenes such as main beams and pier supports that need to resist dynamic loads and fatigue stress.

‌Heavy machinery‌: Used for high-load-bearing components such as heavy crane tracks and port equipment bases to reduce foundation treatment costs.

‌High load-bearing capacity‌: The wide flange design increases the lateral moment of inertia, and the bending resistance is better than that of ordinary I-beams, which is suitable for large-span structures.

‌Good seismic resistance‌: It absorbs seismic energy through plastic deformation and meets the seismic code requirements of high-intensity areas.

Easy processing: The flange and web are of equal thickness, which is convenient for welding, bolt connection and complex node processing.
