W12x30 h beam steel structure material characteristics and mechanical properties
Material: Commonly used materials include A36, A572GR50, A992, etc. Among them, A36 steel has good weldability and plasticity; A572GR50 steel has high yield strength and corrosion resistance; A992 steel has higher yield and tensile strength.
Mechanical performance indicators: If A992 steel is used, its yield strength ≥345MPa and tensile strength ≥450MPa. Its moment of inertia Ix is about 238in⁴, Iy is about 20.3in⁴; section modulus Sx is 38.6in³, Sy is 6.24in³.
W12x30 steel h profile application scenarios
Building structure: It can be used for frame structures of industrial plants and high-rise buildings, such as main beams, secondary beams, etc., to bear floor loads, etc. In some large-span buildings with high space requirements, it can also play its advantages of strong bearing capacity.
Bridge engineering: It is suitable for beams, piers and other structures of urban bridges and some small highway bridges, which can withstand vehicle loads and environmental loads and provide stable support.
Marine engineering: With its good corrosion resistance (such as A572GR50 material) and high strength, it can be used for supporting structures of offshore platforms to resist seawater erosion and wind and wave impact.
GNEE W12x30 h steel profile production and standards
Production process: usually hot rolling process is used to produce, by heating the steel billet to a certain temperature, and then rolling it on the rolling mill for multiple passes to form the required cross-sectional shape and size.
Implementation standards: Implementation of ASTM standards, etc., to ensure that the dimensional accuracy, material properties, etc. of the steel profile meet the relevant requirements.
