Structural A36 Steel Wide Flange Beam W21x57

W21x57 H-shaped steel is a US standard H-shaped steel. The "W" in the model number stands for Wide Flange, "21" means the section height is 21 inches (about 533.4 mm), and "57" means the unit length weight is 57 pounds per foot (about 84.4 kg/m). This steel is named because its cross-sectional shape is similar to the English letter "H" and has superior mechanical properties and structural strength.

High strength-to-weight ratio: optimized cross-sectional design, light weight but strong bearing capacity.
Strong bending resistance: wide and parallel flanges, thin webs, excellent performance when subjected to bending, pressure and eccentric loads.
Convenient construction: right-angle design is easy to install and connect, suitable for a variety of engineering needs.
Cost saving: Compared with ordinary I-beams, it can reduce the use of materials and save 10% to 40% of metal.

Cross-section height: 21 inches (about 533.4 mm).
Unit weight: 57 pounds per foot (about 84.4 kg per meter).
Material: Common materials include A36 h beam material, A572GR50 h beam profile material and A992 h section beam material, which have good mechanical properties and chemical stability.

Architecture and structural engineering: used as load-bearing components such as beams and columns.
Bridge engineering: suitable for supporting structures of large-span bridges.
Industrial facilities: such as petrochemical equipment, power facilities and port conveyor belt supports.
Machinery manufacturing: used for frame structures and beam supports.
Other fields: including underground engineering support structures, shipbuilding, etc.
