For H-beam production, it can be divided into semi-automatic line and automatic line. Semi-automatic line, which is composed of individual machines, consists of CNC cutting machine, H-beam assembly machine, H-beam welding machine and H-beam flange straightening machine. The machines are separate controlled; and the work-piece conveying and overturning are realized by overhead crane. It's very flexible and allows to add machines for different stages to improve the efficiency. Based on the semi-automatic line, it can make up H-beam automatic production line by adding the steel shift machine, overturning machine and conveyors. This line is integrated controlled except H-beam assembly machine and the unloading process of H-beam straightening machine which need the help of overhead crane. All the other feeding and overturning of work-piece can be achieved by means of steel shift machine, overturning machine and conveyors. It has a high degree of automation and  suitable for heavy duty type H-beam production. There are 1.5m, 1.8m and 2.0m H-beam automatic production line which are divided according to the different web sizes.
