A question people often ask is the difference between H-shaped steel and W-shaped steel. The cross-sections of the two steel members are very similar, with wide flanges and similar lengths to the longitudinal webs.
H-shaped steel and W-shaped steel have great similarities in structure. Due to its high torsion force and high bending capacity, it is suitable for horizontal and vertical beams and columns of buildings.
The only difference is how they are made.
W-shaped steel is rolled from molten steel to a certain diameter, gradually forming it into H-shaped steel. When the first process is complete, the beam is sent to a universal milling machine, where transverse and longitudinal rollers hold the beam in place before its profile is finely adjusted to adjust the wings. The width of the face.
H-shaped steel is a three-stage rolled steel, namely wings and web. The three lengths are fixed between the transverse and longitudinal rollers and welded along the entire length of the beam. The strength of H-shaped steel produced by this process is 20% higher than that of W-shaped steel.
