Production technology of hot-dip galvanized corrugated Guardrail !

1. Material Preparation

The key to the production of hot-dip galvanized corrugated guardrail is to select high-quality raw materials. Usually, cold-rolled or hot-rolled plates that have passed quality inspection are used as raw materials for processing. In the material preparation stage, it is necessary to accept the raw materials, check the size, quality, surface state of the raw materials, etc., to ensure that the raw materials meet the production Requirements !

2. Cold Drawing

By cold drawing, the raw material is transformed into a tube shape for the next step of mechanical forming. In the process of cold drawing, it is necessary to pay attention to the selection of the appropriate mold and process, so that the wall thickness of the pipe is uniform, the internal and external surface is smooth, and the size is accurate !

3. Mechanical Forming

In the mechanical forming stage, the cold-drawn pipe is further formed and processed to become a corrugated guardrail plate. In this process, it is necessary to pay attention to controlling the forming parameters to avoid excessive stretching resulting in pipe deformation and cracks !

4. Welding

After the corrugated guardrail plate is mechanically formed, it needs to be welded. The welding material can be selected according to the requirements of different formulations, usually low carbon steel welding wire. In the welding process, it is necessary to pay attention to the control of welding speed, temperature, pressure and other parameters to ensure that the weld is firm and beautiful !

5. Galvanized Treatment

The corrosion resistance of welded corrugated guardrail plate can be improved by hot-dip galvanizing. In the process of galvanizing, it is necessary to choose the appropriate concentration and temperature of zinc liquid, control the time and speed of galvanizing, ensure that the coating is uniform and dense, and give full play to the protective effect of hot dip Galvanizing !

In short, the production of hot-dip galvanized corrugated guardrail needs to go through a number of links, each link needs to strictly control the operation process and precautions to ensure that product quality meets the requirements !
