A36 w12x40 w12x45 steel wide flange beam
W12x40 structural steel h beam
Dimensions (inches): Nominal depth of 12 inches, weight approximately 40 pounds per foot.
Cross-sectional area: Approximately 11.7 square inches.
Material: A36 steel, a common carbon structural steel, has a yield strength of approximately 250MPa (or 36ksi).
W12x45 h section steel beam
Dimensions (inches): Also nominal depth of 12 inches, but weight increased to 45 pounds per foot.
Cross-sectional area: Larger than W12x40 h section steel, approximately 13.3 square inches.
Material: A36 steel, a common carbon structural steel, has a yield strength of approximately 250MPa (or 36ksi).
Characteristics of W12x40 W12x45 H-profile steel
Mechanical properties: A36 steel has a yield strength of about 250MPa (or 36ksi) and good tensile strength, and is used in general building structures, including frames, supports, etc.
Chemical composition: It is mainly composed of iron, and contains a small amount of carbon (maximum 0.26%), manganese (maximum 1.03%), and other trace elements such as phosphorus and sulfur. The proportions of these elements are controlled to ensure the mechanical properties of the steel.
Processing performance: A36 steel beam h is easy to cut, weld and form, and is very suitable for construction projects that require on-site processing and adjustment.
Application areas: Due to good comprehensive performance and economy, W12x40 steel h profile and W12x45 h profile steel are often used in residential buildings, commercial buildings, bridges and other infrastructure projects.
