Advantages of hot dip galvanized hexagon bolts:
Low treatment cost: the cost of hot dip galvanizing antirust is lower than that of other coatings;
Durable: in suburban environment, the standard thickness of hot-dip galvanizing antirust can be maintained for more than 50 years without repair;
Hot dip galvanized bolt is also called hot-dip galvanizing and hot-dip galvanized bolt: it is an effective metal anti-corrosion method, which is mainly used in metal structure facilities of various industries. It is to immerse the bolt after rust removal into the molten zinc at about 500 ℃ to make the surface of the screw attach zinc layer, so as to achieve the purpose of anti-corrosion.
