W27*146 h type beam indicates the specifications of the steel, where "W" stands for wide flange steel, "27" means the height of the steel is about 27 inches (about 685.8mm), and "146" means the weight per foot is 146 pounds (about 66.22kg/m). The specific dimensions are section height 695.45mm, flange width 354.71mm, web thickness 15.37mm, and flange thickness 24.76mm.
The W27*146 h type steel beam made of A36 material has good mechanical properties and processing properties, and is widely used in construction, bridges, machinery manufacturing and other fields.
In the construction field, it is often used to construct beam and column structures of large factories, residential buildings, gymnasiums, etc. In bridge engineering, it can be used as the supporting structure and beam material of the bridge; in mechanical manufacturing, it can be used to manufacture some mechanical parts that bear heavy loads.
