Bearing capacity determined by strengthThe maximum thickness of the member cross section is 18.00mm, according to GB50017-2003, 3.4.1-1, f = 205.00N/mm2According to GB/T 700-1988 and GB/T 1591-1994, FY =225.00N/mm2According to formula 5.1.1-1,N1 = 1 x F X An = 1 x 205 x 67.54 x 102103 = 1384.49kN
Q:What are the acceptance criteria for channel steel?
At present, domestic channel steel specifications from 5 - 40, that is, the corresponding height of 5 - 40cm.

Q:What's the difference between channel type 25a#, 25b# and 25c#?
Channel type 25a#, 25b#, 25c# is to indicate "waist height of the same" channel, but its leg width and waist thickness is different, so you need to add a, B, C to the right of the model to be distinguished. For example, 25a# means 250*78*7. 25b# stands for 250*80*9.
Q:28a difference between channel steel and 28b channel steel
