Dimensions and section properties for W12X58 steel section beam

W12x58 h shaped beam is a US standard wide flange H-shaped steel, widely used in building structures, bridge engineering and other steel structure projects that require high strength and good stability.

Material: Usually made of A36 or A992 steel. A36 is a common carbon structural steel with good mechanical properties; A992 is used for higher-level structural applications, especially for occasions with higher strength requirements.
Standard: Follow ASTM A36 or ASTM A992 standards.

Depth (Height, H): Approximately 12.71 inches (about 323 mm), which is the distance from the top to the bottom, excluding any chamfers or fillets.
Flange Width (Flange Width, B): Approximately 8.020 inches (about 204 mm).
Web Thickness (Web Thickness, Tw): Approximately 0.430 inches (about 10.9 mm).
Flange Thickness (Tf): Approximately 0.685 inches (approximately 17.4 mm).
Cross-sectional Area: Approximately 17.1 square inches (approximately 11032 square mm).
Unit Weight: Approximately 58 pounds per foot of length (approximately 26.3 kg/m).

Yield Strength
For A36 steel: not less than 36 ksi (approximately 250 MPa).
For A992 steel: usually 50 ksi (approximately 345 MPa).

Tensile Strength
A36 steel: ranges from 58-80 ksi (approximately 400-550 MPa).
A992 steel: generally around 65 ksi (approximately 450 MPa).
Elongation: For A36 steel, usually greater than or equal to 20%, indicating that it has good ductility.

Construction engineering: Suitable for load-bearing components such as columns and beams in high-rise buildings to provide necessary support.
Bridge construction: Due to its high strength and stability, it is suitable for the key load-bearing parts of bridges.
Industrial plant: As the main frame material of the plant, it can withstand large loads.
Other large steel structure projects: Such as stadiums, exhibition centers and other large-span buildings.
