hot rolled steel beam W18x192 A572GR50 structure
W18x192 h-shaped iron beam: W stands for "Wide Flange"; 18 stands for the nominal depth, which means the section height is about 18 inches; 192 stands for the weight per foot of length, which is 192 pounds per foot (lb/ft, about 286 kg/m).
A572GR50 h-shaped steel beam: ASTM A572 Grade 50 is a high-strength low-alloy steel widely used in construction and bridges, with good strength, toughness and welding properties.
W18x192 is a heavier wide-flange I-beam with significantly thicker flanges and webs than W18x71 or W18x76, suitable for use in situations where very high loads are present.
Features of A572GR50 h beam profile
A572GR50 h steel profile is a grade in the ASTM A572 standard with the following key properties:
Carbon (C): ≤ 0.23%
Manganese (Mn): ≤ 1.35%
Phosphorus (P): ≤ 0.04%
Sulfur (S): ≤ 0.05%
Silicon (Si): ≤ 0.40%
Yield Strength (Fy): ≥ 50 ksi (approx. 345 MPa)
Tensile Strength (Fu): ≥ 65 ksi (approx. 448 MPa)
Elongation: ≥ 18% (on 2-inch specimen)
Modulus of Elasticity (E): 29,000 ksi (approx. 200 GPa)
Benefits: Compared with conventional A36 steel (Fy = 36 ksi), A572GR50 h profile steel offers higher yield strength for high-strength and lightweight designs. A572GR50 steel h profile has good low temperature toughness and fatigue resistance, excellent weldability, and is suitable for a variety of welding processes (such as SMAW, GMAW).
Uses of W18x192 material h beam
Due to its high weight, high strength and excellent cross-sectional properties, W18x192 (A572GR50) steel beam h is mainly used in the following fields:
Bridge engineering: used as main beams or load-bearing components to support large spans and heavy traffic loads.
High-rise buildings: as core columns, floor beams or seismic components, providing excellent compression and bending resistance.
Industrial facilities: such as heavy machinery platforms, steelmaking plants or port crane supports.
Energy engineering: used for wind power tower foundations or offshore platform structures.
Special structures: such as roof frames of large stadiums and exhibition halls.
Features and Benefits of W18x192 h type beam
High load-bearing capacity: 192 lb/ft weight and thick flange/web design can withstand extremely high static and dynamic loads.
Excellent torsion resistance: Wide flange and thick web significantly improve torsional stiffness.
Economy and strength balance: The high strength of A572GR50 h type steel beam reduces material usage and reduces overall costs.
Durability: Good corrosion resistance and fatigue performance, suitable for projects exposed to harsh environments for a long time (such as bridges).
Processability: Can be easily processed by cutting, welding and bolting.
