w21 x 83 Wide Flange Beam A992
W21x83 h beam steel structure Specifications
Model definition: In W21x83 steel h beam, "W" means wide flange profile, "21" means the nominal section height is 21 inches (about 533mm), and "83" means the theoretical weight is 83 pounds per foot (about 123.7kg/m).
Sectional properties
Typical section height: 533mm (21 inches)
Flange width: about 209-216mm (slightly different from different manufacturers)
Web thickness: ≥18mm, flange thickness: ≥20mm (specific dimensions require reference to the manufacturer's technical manual).
W21x83 h type beam Material and performance
Implementation standard: It complies with ASTM A992 standard and belongs to low-alloy high-strength structural steel (HSLA), adding trace amounts of vanadium (V), niobium (Nb) and other elements to improve comprehensive performance.
Mechanical properties: yield strength ≥345MPa (50ksi), tensile strength ≥450MPa (65ksi)
Elongation ≥18%, carbon equivalent (CE) ≤0.45%, excellent welding performance.
Chemical composition: carbon (C) ≤0.23%, manganese (Mn) 1.0-1.6%, phosphorus (P) ≤0.035%, sulfur (S) ≤0.045%
Alloy elements: vanadium (V) 0.01-0.15%, niobium (Nb) 0.005-0.06%.
W21x83 steel h beam core application areas
High-rise buildings: As the main load-bearing beam or column, it is suitable for large-span frame structures of large commercial complexes and industrial plants; it has outstanding seismic design performance and meets the requirements of building codes in earthquake-prone areas.
Bridge engineering: used for main beams, cross beams and bridge piers to adapt to dynamic loads and fatigue stress environments.
Industrial equipment: heavy machinery base, crane rails, tank supports and other scenes that require high bearing capacity, reducing cross-sectional size and foundation treatment costs.
W21x83 h type beam structural advantages
High strength-to-weight ratio: Compared with ordinary carbon steel (such as A36), the strength is increased by 40%, which can reduce the amount of steel by 20%-30%.
Processing adaptability: The flange and web are designed with equal thickness, which is convenient for cutting, drilling and welding to adapt to complex nodes; the welding process is simplified, suitable for high-strength bolt connections and T-joint fillet welds.
Resistance to lateral deformation: Large lateral moment of inertia, better stability than ordinary I-beam, adaptable to wind vibration and seismic loads.
