The color steel roof of the factory has multiple holes, causing leaks
Thread Content
There are multiple holes in the factory’s color steel roof, causing leaks. What is the cause? Is it corrosion? If the atmospheric environment around is so corrosive, then why haven’t the employees in the factory been corroded? (Production raw materials, products, wastewater, exhaust gas, waste residues – indeed, all of them are highly acidic.)
Does corrosion start from the edge of the plate?
Stainless steel can still rust as well. Nitrogen oxides in the air, high sulfur levels, high temperatures, high humidity, along with coal dust or metal particles – if the outer anti-corrosion layer is even slightly damaged, a large hole can form very quickly
