W33x387 A36/A572GR50/A992 structural h beam
W33x387 wide flange h beam is a specification of American standard H-shaped steel, where "W" stands for wide flange H-shaped steel, "33" refers to its nominal depth of 33 inches (about 838.2 mm), and "387" represents the weight of 387 pounds per foot (about 194.5 kg/m). This type of steel is usually used in heavy structural projects that require high load-bearing capacity.
A36, A572GR50, A992 h beam steel structure material comparison
A36 h shaped beam material is a carbon structural steel with a low carbon content, a yield strength of at least 36,000 psi (about 250 MPa), and good weldability and formability, suitable for general building structures.
A572GR50 h type steel beam material is a low alloy high strength structural steel with a minimum yield strength of 50,000 psi (about 345 MPa), which is stronger than A36 and suitable for applications requiring higher strength.
A992 structural steel h beam material is another low alloy high strength steel, commonly used to make W-beams, with a standard yield strength range of 50,000 to 65,000 psi (about 345 to 450 MPa), and has excellent welding and machinability.
