Even if you have cold galvanizing process coil, it will help it become much more durable and proof against the cold and warm weather. What you must realise would be that the galvanizing process, just like it is, can be improved upon by using the hot dip process using zinc.

Hot dip galvanizing is slightly distinct from the cold galvanizing process. The main difference is visible within the final product. You will notice a distinct sharp and smooth finish on the exterior of galvanized steel. However, any one of these metals which are dipped into zinc will have a much more rough appearance.
