W16x67 W16x77 A36 h steel beam
W16x67 h section steel beams: section height 415mm, flange width 260mm, web thickness 10mm, flange thickness 16.9mm, theoretical weight about 100kg/m.
W16x77 h shaped beam: section height 420mm, flange width 261mm, web thickness 11.6mm, flange thickness 19.3mm, theoretical weight about 114kg/m.
Moment of inertia: The flange thickness and web thickness of W16x77 h-shaped iron beam are greater than those of W16x67, and the bending moment of inertia is increased by about 15%-20%.
Section modulus: The section modulus of W16x77 h-shaped steel beam is higher, which is suitable for larger spans and load requirements.
Chemical composition of A36 h type beam: carbon content ≤0.25%, manganese 0.8%-1.2%, silicon ≤0.4%, phosphorus ≤0.04%, sulfur ≤0.05%, copper content ≤0.2%, low carbon design ensures weldability.
Mechanical properties of A36 h type steel beam
Yield strength: ≥250MPa (36,000psi), meeting general structural load requirements.
Tensile strength: 400-550MPa, higher strength when thickness ≤20mm.
Elongation: ≥20%, excellent toughness, can adapt to cold bending, stamping and other processing.
Typical application scenarios of A36 material h beam
Building structure: heavy roof trusses of industrial plants, load-bearing columns of multi-story buildings, can withstand loads ≥300kN/m²; shelf support beams in storage and logistics centers, using high section modulus to reduce flexural deformation.
Bridges and transportation facilities: main beams or pier support structures of small and medium span bridges, adapting to dynamic loads and fatigue stress; canopy frames of rail transit platforms, taking into account both lightweight and strength requirements.
Machinery and industrial equipment: port crane track beams, heavy machinery bases, using the toughness of A36 steel to resist impact loads.
