1. Wide airfoil H-shaped steelType specifications: Common wide flange H-shaped steel type specifications are usually expressed by height multiplied by width, generally including 100*100, 125*125, 150*150, 175*175, 250*250, 300*300, 350*350, 400*400 and other models.
Presentation method: The wide flange H-shaped steel type is usually expressed in the way of height H* width B* web thickness * wing thickness, usually showing that the size of its height is the same as the width size.
2. Middle flange H-shaped steelType specifications: The common middle flange H-shaped steel type specifications are usually expressed by height multiplied by width, mainly including 150*100, 200*150, 250*175, 300*200, 350*250, 400*300, 450*300, 500*300, 600*300 and other models.
Expression method: The expression method of the middle flange H-shaped steel type is the height h multiplied by the width B multiplied by the thickness of the web T1 multiplied by the thickness of the wing T2. Usually, the size of the height is different from the size of the width, and the height is slightly larger than the width. For example, the middle flange H-shaped steel of 250*175 model specifications is represented by 244*175*7* 14,450 *300 model specifications, and the representation is 440*330*11*18.
