A992 W16x89 H-section steel beam
The nomenclature for W16x89 structural steel h beam follows ASTM standards: W for wide flange; 16 for nominal height in inches, approximately 16 inches; and 89 for weight per foot of length in pounds (lb/ft), or 89 lb/ft.
ASTM A992 structural h beam is a high-strength, low-alloy structural steel designed for wide flange sections with the following properties:
Yield Strength: 50 ksi (approximately 345 MPa), minimum.
Tensile Strength: 65 ksi (approximately 448 MPa), typically in the range of 65-80 ksi.
Elongation: At least 18% at 8-inch gauge length, indicating good ductility.
Carbon (C): ≤0.23%
Manganese (Mn): 0.5%-1.6%
Silicon (Si): ≤0.4%
Phosphorus (P): ≤0.035%
Sulfur (S): ≤0.045%
Carbon equivalent (CE): ≤0.47%, ensuring good welding performance.
A992 h beam structure has higher strength and better fatigue resistance than traditional steels such as A36 h section beam, while maintaining excellent weldability and toughness. W16x89 is usually produced by hot rolling process, and the steel billet is formed at high temperature to ensure material uniformity and surface quality. The composition of A992 steel h column is strictly controlled and suitable for the high standards of modern steel structures.
W16x89 (A992 material) h section steel is suitable for the following scenarios due to its moderate weight and excellent mechanical properties:
Building structure: beams, columns or frame supports of medium and high-rise buildings.
Bridge engineering: secondary beams or supporting members of small and medium span bridges.
Industrial facilities: load-bearing structures in factories and warehouses.
Earthquake-resistant design: The high toughness and ductility of A992 h-shaped steel make it an excellent performer in earthquake-prone areas.
Advantages of A992 W16x89 h-beam
High strength: The 50 ksi yield strength of A992 steel h-beam is better than that of traditional A36 (36 ksi), which can reduce material usage.
Weldability: Low carbon equivalent design makes welding easier and less prone to cracking.
Economical: Moderate weight (89 lb/ft), a balance between strength and cost.
Earthquake resistance: Good ductility, suitable for dynamic load environments.
