FAQ
What is a pre galvanized steel pipe?
A pre galvanized steel pipe is made from steel coil that has been zinc-coated before forming and welding. This process ensures internal and external corrosion protection and a smooth, uniform finish.
What’s the difference between pre galvanized and hot-dip galvanized steel pipe?
Pre galvanized pipes are zinc-coated before shaping, typically with thinner coatings (40–60g/m²), while hot-dip galvanized pipes are immersed in molten zinc after fabrication, providing thicker coatings (≥200g/m²) and better long-term corrosion resistance.
What is a pre galvanized round steel pipe used for?
A pre galvanized round steel pipe is commonly used in fences, greenhouses, handrails, furniture frames, and light construction applications where a smooth finish and moderate corrosion protection are needed.
