The two tons of electric gourds are made of the large amount of steel
It doesn't matter that the steel or the steel you need is outside the normal standard. As long as the manufacturer is told on the order, the manufacturer will give you the order for your electric gourd. In other words, the choice of steel is not good, but it doesn't matter if it's big. But the choice is too big to waste. So, the main thing is to be suitable. I hope the above question can help you, if you have any questions, please consult me again.
Choose the type of steel, and make sure that it is safe, not economical. The choice is small, the electric gourd does not mount, and the steel is not enough. Also, if you are buying the steel in the market, you must buy it on the big one. Because the so-called national standard and steel of the market, not necessarily the national standard, may be less than the actual steel of the actual national standard, the bearing force is less than that.
The normal standard is the type of i-steel, which is within the range of 20a-32c. However, the choice of steel and steel is also related to the length of the track of the electric block, which is the span of the i-steel. It also has to do with the way the steel is installed. It is steel structure, whether it is built in advance, whether it is built in advance, or whether it is full Angle, or the expansion bolt. If the support points are far apart, the length is long. A: then the steel is not suitable for small models. Choose the larger model. Otherwise, the capacity of the steel is unreliable. According to the actual situation, choose the steel that suits you better.
