It's not clear what difference between I-beam and channel steel What's the difference between the formulas for the two materials?
Different from H steel and I-beam, H steel is better than I-beamGB_706-1988_ dimensions, shape, weight and allowable deviation of hot rolled I-beamGB_T_11263-2005_ hot rolled H and split T section steel
Channel steel is a strip of steel with a cross section. Its specifications are h, * leg width (b) * waist thickness (d) mm number, such as 120*53*5, which means waist height of 120 mm, leg width of 53 mm channel, waist thickness of 5 mm channel, or 12# channel steel. The same channel such as high waist, there are several different legs wide and thick waist also need B C should be distinguished in the model to the right a, such as 25a# 25b# 25c#
I-beam, also called steel girder, is a long strip steel with cross section. Wing to the edge of the root cause of I-beam thinning, have a certain angle,I type is Arabia digital cm with its waist high number to represent, web and flange thickness and flange width of different specifications to the waist high (H) * (b) * waist leg width thickness (T). The number of said, such as "160 x 88 x 6", that is 160 mm high waist, leg width is 88 mm, 6 mm thick steel waist. The specifications of I-beam can also be expressed by type. The model indicates the height of centimeters, such as 16#. The same as the waist high beam, there are several different leg width and waist thick, B C to make a difference in the model to the right a, such as 32a# 32b# 32c#. Ordinary I-beam and light steel I-beam, ordinary hot rolled I-beam specifications for 10-63#. Standard Specification for hot-rolled ordinary I-beam supplied by supply and demand agreement is 12-55#. I-beam is widely used in various building structures, bridges, vehicles, supports, machinery and so on.
