Flange plate use

Flange plate is used for welding H-shaped steel. H-shaped steel is divided into hot-rolling and welding. Hot-rolled H-shaped steel is formed by rolling and forming steel once. There are specifications and restrictions. Welding H-beams can be used without specifications. Flange plates are necessary materials for welding H-shaped steels of different sizes. Welding H-beams are assembled by welding three strips of steel plates. The two upper and lower plates are called flange plates and they stand in the middle. The slats are called webs. Usually, the flanges are cut and separated by wide steel plates. This wastes materials, increases consumables, and costs time and labor.
