On a wide flange beam what does W24 x 55 mean?
W24x55 wide flange h beam Specifications
Model Definition
The "W" in W24x55 wf steel beam indicates wide flange profile, "24" indicates the nominal section height is 24 inches (about 610mm), and "55" indicates the theoretical weight is 55 pounds/foot (about 81.8kg/m).
W24x55 w flange beam Specific dimensions
Section height : 610mm (24 inches) Flange width : about 230-235mm (slightly different from different manufacturers) Web thickness : ≥12.7mm, Flange thickness : ≥15.9mm (subject to the manufacturer's technical manual).
W24x55 h beam wide flange Material and performance
Implementation standard
It complies with ASTM A992 standard and belongs to low-alloy high-strength structural steel (HSLA), with high yield strength and excellent welding performance.
Mechanical properties
Yield strength: ≥345MPa (50ksi)
Tensile strength: ≥450MPa (65ksi)
Elongation: ≥18%, Carbon equivalent (CE) ≤0.45%, suitable for dynamic loads and high stress environments.
W24x55 steel wide flange beam Core application areas
Industrial plant: As a large-span roof truss or platform support beam, it has excellent bending resistance and is suitable for dynamic load requirements of the plant.
Bridge engineering: Used for bridge beams or bridge deck support, adapting to the combined stress of vehicle dynamic loads and wind loads.
Heavy machinery: Crane rails, ship deck structures and other components that require high load-bearing capacity, reducing the deadweight of the structure and foundation costs.
W24x55 wide flange beam structural design and advantages
Efficient force-bearing design: The combination of wide flange and thick web significantly improves the bending moment of inertia (Ix), which is 25%-35% higher than the bending resistance of I-beams of the same weight.
Seismic resistance and stability: Excellent plastic deformation capacity, suitable for steel structure construction in earthquake-prone areas.
Convenient processing: The equal thickness design of flange and web simplifies the welding and bolt connection process, and is suitable for complex node structures.
