High-strength hot-dip galvanized bolts have bright colors, high strength and corrosion resistance. They are widely used in outdoor work, such as industrial machinery processing and infrastructure construction, highway fencing, power tower, etc. Generally speaking, the coating of high-strength hot-dip galvanized bolt is thicker, generally 30-60 microns.

The production process of high-strength hot-dip galvanized bolts is to remove oil and rust from the bolts, present a stainless and infiltrating surface, immerse the bolts in the galvanizing bath which melts zinc in advance, and form a layer of zinc coating on the surface of the workpiece. It should be noted that high-strength hot-dip galvanized bolt is generally used in ordinary dry environment. If they are in humid environment for a long time, they will rust for less than half a year.
