SS400, S275JR, ASTM A36/A572 High-Strength H-Shaped Steel for Construction and Engineering Applications
Production technology
H-shaped steel can be produced by welding or rolling. Welding H-shaped steel is to cut the appropriate thickness of the strip to the appropriate width, and weld the flange and web together in the continuous welding set. Welding H-shaped steel has the disadvantages of large metal consumption, difficult to ensure uniform product performance, and limited size specifications. Therefore, H-shaped steel is mainly produced by rolling method. In modern steel rolling production, the universal mill is used to roll H-shaped steel. The web plate of H-shaped steel is rolled between the upper and lower horizontal rolls, and the flange is simultaneously rolled between the side of the horizontal roll and the vertical roll.
Main Types
(1)Wide Flange Beams (W-Beams):
Flanges are wider than the web, providing better load distribution.
Commonly used in building frames and bridges.
(2)Junior Beams (S-Beams):
Narrower flanges compared to W-beams.
Used in lighter structural applications.
(3)Pile Beams (HP-Beams):
Flanges and web have similar thickness, making them ideal for deep foundation piles.
