Hot rolled profiled steel is a brittle material, so when selecting manufacturers, we should pay more attention to the strength and technical guarantee of enterprises.
The disadvantages of hot rolled profile steel are:
1.Residual stress caused by uneven cooling.
2. The non-metallic inclusions in hot-rolled profile steel will form interlayer, which may lead to interlayer fracture during welding shrinkage.
3.It is difficult to control the thickness and width of hot rolled profile steel products.
