Surface treatment equipment of metal plates for civil construction site

The invention relates to metal plate surface treatment, in particular to surface treatment equipment of metal plates for a civil construction site. The surface treatment equipment comprises a grindingsupport, a horizontal moving mechanism, pulling supports, pulling mechanisms, a grinding mechanism, perforating supports, a clamping mechanism and perforating mechanisms. The clamping mechanism can be used for clamping rectangular metal plates with different dimensions, the four perforating mechanisms are used for perforating four corners of each metal plate, each perforated metal plate is placedon the four pulling mechanisms which can pull the rectangular metal plates with different dimensions, the four pulling mechanisms provide pulling force to keep the metal plates in a tensioned state,the grinding mechanism can grind the rectangular metal plates with different dimensions, and the grinding planeness of the plates is guaranteed under the acting force of the pulling mechanisms. 本发明涉及金属板表面处理，更具体的说是一种土木施工现场用金属板材表
