Traditional galvanized metal roofing is straight carbon steel that has been turned into a sheet and corrugated. Then, it has been finished with a galvanized coating. The coating is made by dipping the sheet in hot, molten zinc. Then, the heated zinc ions bond to the iron molecules on the surface. This creates a shiny metal that is resistant to rust. This process is called galvanization.

Steel coils refer to a finished steel product that’s manufactured out of slabs. Slabs are considered semi-finished steel materials made from ingots. Producing steel coils out of slabs can be done in different ways — hot rolling, cold rolling, or electrolytic tinplate (EPT). Once all of the major production processes have been completed, the resulting rolled material can now be used in various industries for assembly or further fabrication. Knowing this, steel coil uses can vary depending on the industry, but some of its most popular and widely-known applications include pipe-manufacturing, structural steel members, electronic components, consumer goods, automotive parts, and many more.
