ASTM H-Shaped Steel A992 and A36 steel w30x132
W30×132 h steel profile Specifications
W: indicates wide flange H-shaped steel, whose flange width is relatively close to the web height, and the cross-sectional mechanical properties are more balanced, and can better withstand various loads.
30: represents the cross-sectional height of about 30 inches, which is about 762mm when converted into metric units (the actual size may vary slightly due to different manufacturers and production processes).
132: indicates that the theoretical weight per foot of length is about 132 pounds, and the theoretical weight per meter after conversion is about 196.2kg/m.
A992 h beam section Material characteristics
High strength: The yield strength is usually not less than 345MPa (50ksi), and the tensile strength is between 450-620MPa. It has excellent bearing capacity and can withstand large loads. It is suitable for structures with high strength requirements.
Good toughness and fatigue resistance: It has high elongation and good impact toughness, can maintain good performance under dynamic loads, has a long fatigue life, and improves the safety and durability of the structure.
Excellent welding performance: easy to weld. Through appropriate welding process and materials, the strength and toughness of the welded joint can meet the requirements, which is convenient for connection and assembly at the construction site.
Good corrosion resistance: some alloy elements are added to make it have better corrosion resistance than ordinary carbon steel under atmospheric environment and other conditions, reducing maintenance costs and extending service life.
A36 h beam steel structure material characteristics
Chemical composition: carbon (C) content ≤0.26%, manganese (Mn) content ≤1.65%, silicon (Si) content ≤0.40%, phosphorus (P) content ≤0.04%, sulfur (S) content ≤0.05%.
Mechanical properties: yield strength ≥250MPa (36ksi), tensile strength 400 - 550MPa, elongation ≥20%. Its strength is relatively low, but it has good plasticity, toughness and welding performance, which can meet the general building structure and non-load-bearing requirements.
Economical: The cost is relatively low. In some projects that do not require particularly high steel performance, the use of H-shaped steel made of A36 can reduce project costs.
Application areas of W30×132 steel beam h
High-rise buildings: Due to its high strength, A992 is more suitable for super-high-rise buildings or parts with high structural bearing capacity requirements; A36 can be used for parts of some medium and high-rise buildings with strict cost control.
Industrial plants: H-shaped steel made of A992 can withstand the load of heavy cranes, while A36 can be used for plant structures with general loads.
Large bridges: It can be used as the main beam structure of the bridge, especially H-shaped steel made of A992, whose high strength and good toughness can withstand the dynamic load and alternating stress of the bridge during use. It is more common in some cross-sea bridges, large urban overpasses and other projects.
Small and medium-sized bridges: A36 material W30×132 H-shaped steel can also be used for some small and medium-span bridge structures, which can meet the load-bearing requirements of the bridge and have good economy.
