Assessment and Preparation: Identify the areas of the metal structure that require waterproofing. This could include roofs, walls, tanks, or any other exposed metal surfaces.

Selecting the Waterproofing Method: Determine the appropriate waterproofing method based on the specific requirements of your industrial application. Options include coatings, membranes, sealants, or specialized paints.

Choosing the Waterproofing Material: Select a waterproofing material that is suitable for the type of metal and the environmental conditions in which it will be used. Consider factors such as the material's durability, resistance to chemicals, and environmental impact.

Curing and Drying: Allow the waterproofing material to cure or dry according to the manufacturer's recommendations. This may involve a waiting period before the metal sheet can be exposed to moisture.

Quality Control: Inspect the waterproofed area to ensure that the application is uniform and free of defects. Check for any areas where the waterproofing material may have not adhered properly.

Maintenance and Inspection: Establish a regular maintenance schedule to inspect the waterproofed metal surfaces for signs of damage or wear.
