Galvanized fasteners are fasteners that enhance their corrosion resistance by coating the metal surface with a layer of zinc. They are widely used in industries such as construction, automobiles, and power. Here is a detailed introduction:
Core Feature
The galvanized layer is formed through electroplating or hot-dip galvanizing processes, with a thickness typically ranging from 5 to 15 micrometers. It effectively isolates the metal from corrosive environments (such as moisture and acidic gases), thereby extending the service life.
Common types
Screws/Nuts: Such as hexagonal head screws and stud bolts, commonly used for steel structure connections.
Self-tapping screws: Suitable for quick installation of thin sheet metal parts.
Bolts: Mostly used for permanent connections in lightweight structures.
Application scenario
Construction industry: Outdoor structures such as bridges, curtain walls, and roof supports.
Automobile manufacturing: Rust-proof connections for vehicle body chassis and engine components.
Power equipment: Fasteners for transmission towers and distribution boxes for protection.
Advantages and Limitations
Advantages: Lower cost compared to stainless steel, superior corrosion resistance to ordinary steel.
Limitations: Not suitable for high-temperature or strong acid-base environments. White rust (oxidation of the zinc layer) may occur after long-term use.
