21 August 2019


Rust, a form of iron oxide that occurs when iron combines with the oxygen in the air, causes iron to corrode and metal to expand, weaken and become brittle. It is also permeable to air and water, so the metal beneath the rust layer will continue to corrode. The presence of rust creates safety hazards for employees and costs global industry several billions of dollars every year.
