W21x48 h beam structure materials and standards
Implementation standards: Conforms to ASTM A36 h beam structure material, A572 Gr.50 h section steel material and A992 h type beam material American standard steel standards, with high strength, corrosion resistance and welding performance.
Mechanical properties: Typical yield strength ≥345MPa, tensile strength ≥450MPa, elongation ≥18%.
Main application areas of W21x48 h type steel beam
Building structure: Suitable for scenes such as factory trusses and large-span beam-column supports, with excellent bending and compression resistance.
Industrial equipment: Used for components that require high load-bearing capacity, such as heavy machinery bases and ship deck structures.
Bridge engineering: Can be used as a pier or bridge deck support member to adapt to complex load environments.
Structural advantages of W21x48 h section steel
High rigidity design: The H-section optimizes the balance between weight and strength and reduces material waste.
Easy processing: The equal thickness design of flanges and webs facilitates cutting, drilling and welding, and is suitable for complex nodes.
Strong stability: Large lateral moment of inertia, and better resistance to lateral deformation than ordinary I-beams.
