I-beam type specification size comparison table

I-beam specifications dimensions are as follows:

1, I-beam 10-18, its length is roughly 5~19m.

2, I-beam 20-63, its length is about 6~19m. when the length of the I-beam is more than 8m, the deviation is allowed to increase by about 5mm for every 1m increase, but the total deviation is not greater than 80mm. When the length of I-beam is more than 8m, every 1m, the deviation is allowed to increase about 5mm, but the total deviation is not more than 80mm.

I-beam advantages

1, I-beam's flange is wider, and the hardness of the side of the flange is bigger, so that it has a strong bending ability, and it is not easy to travel to the bending situation later on. In addition, for the two surfaces of the wing edge, are parallel to each other, also makes the subsequent installation process becomes more convenient, reducing the difficulty of construction.

2, I-beam and ordinary types of steel is completely different, the cost is lower, less residual stress, and accuracy will be much higher. And welded I-beams used in the price of materials than welding the ordinary type of steel will be much lower, there is no need for weld testing, can save the cost of about thirty percent.

3, if you choose the same cross-section steel type, the weight of I-beam steel will be lower than the traditional structure of the steel weight, but the load-bearing capacity is better. And I-beam steel structure compared with the concrete structure, then you can increase six percent, the weight is reduced by about 20 percent, so that the internal force of the structural design becomes smaller.
