The W12 X 87 structural beam A 36 steel
The "W" in W12x87 stands for Wide Flange, "12" means the section height is approximately 12 inches (304.8mm), and "87" means the weight per foot of length is 87 pounds (approximately 129.5kg/m).
W12x87 wide flange beam Common materials
A992: Most commonly used in building structures, yield strength = 50ksi (345MPa), tensile strength = 65ksi (448MPa), with high strength and good toughness.
A572 Gr50: Yield strength is equivalent to A992, slightly better corrosion resistance, suitable for exposed or harsh environments.
A36: Low-strength steel, rarely used in heavy components such as W12x87.
What applications can W12x87 wide flange h beam be used in?
W12x87 h beam wide flange is a heavy duty wide flange steel section suitable for structural scenarios requiring high load carrying capacity and stiffness.
1. Building structure
Frame columns of high-rise buildings: as the main load-bearing columns, they bear vertical loads, horizontal wind loads, and earthquakes.
Long-span main beams: such as roof beams of industrial plants and gymnasiums, or load-concentrated floor beams (such as equipment floors and parking lots).
Transfer layer structure: transfers upper loads to the bottom column grid in complex buildings.
2. Bridge engineering
Highway/railway bridge main beams: bear vehicle dynamic loads, requiring high strength and fatigue resistance.
Bridge piers or supporting structures: used in heavy projects such as cross-sea bridges and viaducts.
3. Industry and infrastructure
Heavy machinery frames: such as port cranes and large equipment bases, resist vibration and impact loads.
Offshore platform structures: when using weathering steel materials (such as A572 Gr50), they can be used for load-bearing columns or support beams in marine engineering.
4. Special engineering
Structures in high-intensity earthquake zones: A992 material has good ductility and is suitable for earthquake-resistant design.
Heavy-duty railway track beams: withstand repeated loads from trains and require high durability.
