Hot-dip galvanizing is a key technology for metal corrosion protection, forming a corrosion-resistant coating by immersing the workpiece in molten zinc. Temperature control and the quality of the zinc liquid are important for the quality of the coating.
Hot-dip galvanized bolts are widely used in construction, transportation, and power industries such as bridges, automotive components, and transmission towers, which enhance their corrosion resistance and durability.
There are various types of hot-dip galvanized bolts, classified based on different criteria:
1. Carbon Steel Hot-dip Galvanized Bolts: Made of carbon steel, the surface forms a uniform zinc layer after hot-dip galvanizing to enhance its corrosion resistance.
2. Stainless Steel Hot-dip Galvanized Bolts: Made of stainless steel, known for its corrosion resistance, can also undergo hot-dip galvanizing for further protection.
Classification by Structure:
1. Standard threads and head shape, suitable for general fastening needs.
2. High-Strength Hot-dip Galvanized Bolts: Made of high-strength materials with higher -tensile and yield strength, suitable for applications requiring high fastening force.
3. Special Hot-dip Galvanized Bolts: Bolts designed for specific requirements like anchor bolts, and foundation bolts, with unique structures and functions.
Classification by Surface Treatment:
1. Surface treated with hot-dip galvanizing, forming a dense zinc layer with excellent corrosion resistance.
2. Hot-dip Galvanized with Coating Bolts: Coating is applied on top of hot-dip galvanizing to increase weather resistance and aesthetics.
