What is the supply length of 30# I-beam?
30# I-beam is only 12 meters, divided into 2 models. 30#A size 300*126*930#b size 300*128*1130# I-beam no C, no 30#C mills are upstairs. I am a Xi'an 30#A section of the national standard 30#B, 2020 yuan (including tax), a national standard of 2220 yuan (including tax)
I-beam, also called steel girder, is a strip of steel with an I-shaped section. I-beam is made of ordinary I-beam and light i-beam. It is a section steel with an I-shaped section. I-beam is mainly divided into ordinary I-beam, light I-beam and H steel three. Due to the relatively high section size and narrow width of ordinary I-beam and light I-beam, the moment of inertia of the two main sleeves of the cross section is different greatly.
The supply length of 30# I-beam is usually 12 meters. The length of the steel bar is generally 9m and 12m; the length of the I-beam and H section steel is generally 12m; the factory length of the angle steel is generally 6 meters; the common length of the channel steel is 6 meters, /8 meters and /9 meters.
