The anti-corrosion measures of steel rods adopt internal and external hot-dip galvanization. The galvanizing process undergoes pickling, hot-dip galvanization, water washing, phosphating, passivation and other processes. The galvanized layer has a smooth and elegant overview, consistency of luster, no wrinkles, falls, zinc tumors, skinning, spots, yin and yang surfaces, etc. Traffic sign poles are also called road sign poles, highway sign poles, and columns on both sides of the highway are used to indicate traffic routes. It is mainly made of steel pipes and the surface is hot-dip galvanized.
The main problem in aluminum plate splicing is that the rivet marks are obvious after aluminum plate splicing, and the reflective film at the splicing is prone to zigzag cracks. The solution is to first put the aluminum plate at the rivet into the size of the rivet, and then use a grinding wheel to smooth the rivet head, which basically solves the problem of obvious rivet marks. In order to prevent irregular cracks, after applying the film, the reflective film will be artificially broken into a straight line at the joint of the aluminum plate. The high-strength reflective film has poor toughness and hardness, so the engraving process requires sharp engraving tools.
