Some people say that China Tower Corporation’s acquisition of the assets of the three major operators is to reduce costs and avoid waste. The tower will become a giant in infrastructure services. Some people think that the three major operators have huge capital for renting towers and hinder the development of operators. No matter how the basic iron tower is the foundation of the operator, the construction of the iron tower is particularly important. Here we are discussing the steel structure bolts used for the construction of the iron tower. Fix the support of the iron tower, make one iron tower support and one iron tower support connected, and finally form a huge iron tower, which is used to transmit information and benefit the people.
　

Steel structure bolts generally use 35# steel or other high-quality materials. After they are made, heat treatment is performed. The selection of steel structure bolts is very important, which directly leads to the quality of steel structure bolts. 40Cr materials are harder and prone to accidents. It is best to use 35CrMo to ensure the quality but the cost is high. 20MnTiB can only be used for some small-sized steel structure bolts.
