The treatment cost of hot-dip galvanized Roofing Bolts is actually very low. This is a conclusion compared with other paint coatings. In fact, the coating on the roof bolt or the coating on other fasteners is actually used to prevent rust and corrosion. It is the least expensive to deal with the types of roof bolts, and the longer the protection, the longer Not to mention hot-dip galvanized, hot-dip galvanized roof bolts are low in cost and fair in the market. Most people still choose this type of roof bolts for purchase, so they can save a lot of money. Let me briefly introduce to you why the cost of hot-dip galvanized roof bolts is so low when galvanized.

The principle of hot galvanizing
The principle of hot dipped galvanizing is simply to immerse the cleaned iron parts into the zinc bath through the wetting effect of the plating aid, so that the Round Head Bolt and molten zinc react to form an alloy Film. For a good hot-dip galvanizing operation, each process should fully play its role under strict control. And if the operation of the previous process is not good, it will cause a chain of adverse reactions in the subsequent processes, which will increase the operating cost or cause poor hot-dip galvanized products. If the pretreatment is not good, the molten zinc cannot fully react with the round head bolts normally, forming the most perfect galvanized film structure. If the post-treatment is not good, the appearance of the galvanized film is damaged, and the product value is reduced.
