The manufacturing process in custom galvanized iron coil factories generally involves several key steps. First, high-quality steel sheets are sourced, which serve as the base material. These sheets go through continuous hot-dip galvanization, where they are immersed in molten zinc. This process is crucial because it creates a strong metallurgical bond between the steel and the zinc, ensuring superior corrosion resistance.

The manufacturing of corrugated roof sheets follows specific standards that define the acceptable thickness levels. These standards can vary based on the material used, such as steel, aluminum, or fiberglass. Typically, the thickness of corrugated metal roof sheets may range from 0.3 mm to 1.2 mm, with common choices being 0.375 mm, 0.5 mm, and 0.6 mm.
