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.

Once the materials are prepared, they undergo a meticulous extrusion process where they are shaped into sheets of various thicknesses and sizes. Cutting-edge machinery allows for precise measurements, ensuring that the slip sheets are custom-fit for different roofing applications. After shaping, the sheets are subjected to rigorous quality control tests, checking for durability, flexibility, and the ability to withstand environmental stresses.
