Galvanized 933 hexagonal bolt
The advantages of galvanized bolts include low processing costs, long-lasting durability, good fixation, comprehensive protection, and time-saving and labor-saving. The rust prevention cost of hot-dip galvanized screws is lower than that of other paint coatings. The rust prevention thickness in ordinary environments can be maintained for more than 30 years without corrosion, and in coastal areas, it can be maintained for 20 years without rust. The galvanized layer and steel are made of the same material, and the combination of zinc liquid and screws is very fixed, without any detachment. The galvanizing process is fast and can avoid the time required for painting on the construction site after installation
