A572GR50 W12x170 190 Structural Steel H Beam

A572GR50 h section beam is a 50 grade steel in the ASTM A572 standard, which belongs to high-strength low-alloy steel with excellent strength, ductility, weldability and corrosion resistance. The "50" in the name indicates that its minimum yield strength is 50 ksi (about 345 MPa). A572GR50 h shaped beam improves strength by adding trace alloying elements such as niobium and vanadium while maintaining good processing properties.

Features of W12x170 W12x190h beam structure
W12x170 steel h beam: Relatively light, suitable for structures that require high strength but are weight-constrained, such as bridge supports or secondary beams in high-rise buildings.

W12x190 h beam: Heavier and larger in section, providing higher load-bearing capacity and bending resistance, suitable for primary beams or structures subject to heavy loads.

Both are "W12" series, about 12 inches in height, but the thickness of the flanges and webs, as well as the weight, vary significantly, affecting their bending and shearing capabilities.

Application of A572GR50 h section steel in W12x170 h section steel and W12x190 h shaped steel
A572GR50 h shaped steel's W12x170 and W12x190 sections are commonly used in the following areas due to their high strength and low weight ratio:
Bridge construction: Used as a main beam or cross beam, providing sufficient strength and fatigue resistance.
Building structures: used for columns and beams in high-rise buildings, especially when earthquake-resistant design is required.
Industrial facilities: such as heavy machinery support frames in factories.
Marine engineering: its corrosion resistance makes it suitable for certain offshore structures.
