PRE-GALVANIZED STEEL SQUARE/RECTANGLE TUBE

* Process: Pre-galvanized steel pipes are galvanized before they are formed into the final product. The galvanization process typically 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 uniform appearance.

* Application: Pre-galvanized pipes are often used in applications where the final appearance is important, such as in outdoor structures, fencing, and decorative applications.

HOT-DIP 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 coating. The coating is usually more uneven, but it provides greater protection against corrosion.

* Application: Hot-dip galvanized pipes are commonly used in applications where corrosion resistance is a critical factor, such as in water pipelines, construction, and outdoor structures exposed to harsh environments.
