PRE-GALVANIZED STEEL SQUARE/RECTANGLE TUBE
* Process: Pre-galvanized steel pipes are galvanized before they are formed into the final product. The galvanization processtypically involves coating the steel with a layer of zinc through either a hot-dip process or an electroplating process.* Appearance: Pre-galvanized pipes have a smoother and more even zinc coating. The surface is usually shinier and has a uniformappearance.* Application: Pre-galvanized pipes are often used in applications where the final appearance is important, such as in outdoorstructures, fencing, and decorative applications.
HOT-DIP GALVANIZED STEEL SQUARE/RECTANGLE TUBE
* Process: Hot-dip galvanized steel pipes are formed first and then immersed in a molten bath of zinc. The immersion process results in a thicker and more durable zinc coating compared to pre-galvanized pipes.* Appearance: Hot-dip galvanized pipes may have a rougher surface compared to pre-galvanized pipes due to the thicker zinc co…
