Hot rolled I beam steel, also called steel girder, is strip steel product with I shaped cross-section. Its cross-sectional size is represented by web height * flange thickness * web thickness in millimeter. For instance, the "I 160×88×6" stands for 160mm web height, 88mm flange thickness and 6mm web thickness. The other marking method is represented by model or web height in centimeter, e.g. I 16 #. If the product with the same web height but different web thickness and different flange width, you can add these letters a, b, and c to the right side of model for distinguishing each other, e.g. 32#a, 32#b, 32#c, etc.

Generally speaking, this steel product is divided into two categories which are common type and light type. The common type is expressed by GB706-88 or GB 1591-79. And the light type YB163-63 offers wider flange, thinner web and flange compared with the common one with the same height. In addition, light type I-shaped steel provides higher stability and it is more economical than the former one.

  • H Beam SteelH beam steel is named by its H-shaped cross-section. It is convenient and simple to connect, manufacture, and install due to its parallel flanges. Compared with reinforced concrete structure, this H-shaped steel increases 6% in usable floor area, but decreases its dead load by 20% ~ 30%. In addition, this product can be manufactured into T-shaped steel, greatly meeting the requirements of engineering projects.
  • Square TubeSquare tube refers to a kind of tubular product with equal sides. It is manufactured from Q235 hot rolled strip steel, cold rolled strip steel or plate rolling by cold bending cold forming, and then high frequency welding.
