Steel I beam-Q355B

Q355B Steel I beam Features

Due to the relatively high and narrow cross-section sizes, the moment of inertia of the two main sleeves are quite different, which limits the application of the common i-beam and light i-beam. The use of i-beams shall be selected according to the requirements of the design drawings.

Processing Technology Of Q355B Steel I beam

The flange of ordinary i-beams and light i-beams is gradually thinned from the root to the edge at a certain angle. The models of ordinary i-beams and light i-beams are represented by the Arabic numerals of the number of centimeters in their waists, web, flange thickness and flange width of different specifications to waist height (h) × leg width (b) × waist thickness (d) of the number of millimeters, such as “General work 160 × 88 × 6”, that means waist height of 160 mm, leg width of 88 mm, waist thickness of 6 mm common i-beam. /“Light Industry 160 × 81 × 5”means light i-beam with a waist height of 160 mm, a leg width of 81 mm and a waist thickness of 5 mm. The specification of common i-steel can also be expressed by model number, which indicates the number of centimeters of waist height, such as common i-steel 16 # . If there are several different leg widths and waist thicknesses, a B C should be added to the right side of the model, such as 32 # A, 32 # b, 32 # C, etc. . Standard Specification for hot-rolled plain i-beams is 10-63 # . The size of hot-rolled common i-beam supplied by agreement of both the supplier and the demander is 12-55 # .
