High-strength color-coated galvanized bolts are widely used in road bridges, engineering building steel frame structures, large machinery and other projects that must be rigidly connected. The galvanized layer on the surface of high-strength galvanized bolts has high corrosion resistance, which can have a stronger protection effect on the bolts. There are two main methods of galvanizing, namely electro-galvanizing and hot-dip galvanizing. Among them, the cost of galvanizing is lower and the coating is uniform, while the coating of hot-dip galvanizing is thicker and has good corrosion resistance. 1. Low cost of high-strength galvanized bolts: the cost of high-strength galvanized bolts is less than other architectural coatings. 2. Durable: In the natural environment of the suburbs, the thickness of the standard hot-dip galvanized anti-rust treatment can be guaranteed for more than 50 years without maintenance; in urban areas or coastal areas, the standard hot-dip galvanized anti-rust treatment layer can last for 20 years without maintenance. 3. High-strength color-coated galvanized bolts have good stability: the galvanized layer and steel are integrated in the metallurgical industry and become a part of the steel surface, so the durability of the coating is relatively reliable. 4. The coating of high-strength galvanized bolts has strong flexibility: the galvanized layer forms a unique metallurgical structure, which can withstand equipment damage during transportation and use. 5. All-round safety protection: every position of the coating can be galvanized, and sufficient safety protection can be obtained even in dents, bevels and hidden places. High-strength color-coated galvanized bolts are an effective anti-rust coating method, which is suitable for metal component equipment in various fields. The anti-rust treated steel is infiltrated into the molten zinc saturated solution at about 500 ° C, so that the surface of the steel prefabricated component adheres to the zinc layer to achieve the purpose of corrosion resistance. High-quality high-strength galvanized bolts can be used to neutralize the outdoor protection of amusement equipment, but their corrosion resistance is relatively weak in harsh industrial environments and coastal climates. High-strength hot-dip galvanized bolts, hot-dip galvanized screw surface solutions and production processes, low cost, stable and reliable processing technology, and easy to use.
