Pre-galvanized material refers to steel plates, pipes, or other metal products that have been pre-coated with a layer of zinc to improve corrosion resistance and service life. This process typically includes electro-galvanizing or hot-dip galvanizing, depending on application requirements.
Corrosion Resistance: The zinc layer isolates the base material from the environment, preventing oxidation and rust.
Machinability: Pre-galvanized steel retains good mechanical properties for further processing (e.g., stamping, welding, bending).
Surface Quality:
Electro-galvanizing provides a smoother, more uniform surface, suitable for precision machining.
Hot-dip galvanizing offers a thicker zinc layer, ideal for outdoor or high-corrosion environments.
Yes, pre-galvanized material can be used to manufacture long screws (e.g., double-ended studs or anchor bolts), but consider the following:
Material Selection: Carbon steel (e.g., Q235) is commonly used due to its compatibility with galvanizing and mechanical strength.
Processing Methods: Long screws can be made via cold heading, turning, or welding, with galvanizing applied before (pre-galvanizing) or after (post-galvanizing) machining.
Galvanizing Method: Hot-dip galvanizing is preferred for long screws, as it provides a thicker protective layer for heavy-duty or outdoor use.
Handan Chiyi Fasteners: Produces M30×500 hot-dip galvanized hex bolts from Q235 carbon steel for heavy machinery.
FarSun Helical Ground Screws: Uses hot-dip galvanized Q235B steel, with lengths up to 3000mm (customizable).
