* 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.
