W21x44 A36/A572GR50 w shape structural steel
Basic parameters
Model identification: W21x44 structural h beam belongs to the American standard wide flange H-beam (W series), where "21" means the section height is about 21 inches (533.4mm), and "44" represents the theoretical weight of about 44 pounds per foot (65.5kg/m).
Material standard
A36 h section beam: carbon structural steel, yield strength ≥250MPa, good elongation, suitable for general building structures.
A572GR50 h beam structure: low alloy high strength steel, yield strength ≥345MPa, better corrosion resistance and load-bearing capacity, suitable for heavy machinery and bridges.
Dimensions and specifications
Typical dimensions (refer to similar W21 series h-shaped steel):
Web height: about 21 inches (533.4mm)
Flange width: about 6.5-8.25 inches (165-210mm)
Web thickness: about 0.35-0.65 inches (8.9-16.5mm)
Flange thickness: about 0.45-0.95 inches (11.4-24.1mm).
Sectional characteristics: high section modulus, lightweight design, optimized bending and compression performance.
Application scenarios
Architectural field: high-rise steel structure, industrial plant support (using the weldability and economy of A36).
Heavy structure: bridges, port machinery (the high strength of A572GR50 is suitable for dynamic load environment).
Other fields: power tower, mining equipment, vehicle manufacturing, etc.
