Blasting is a proven method of removing rust, rolling mill skin and other coverings. During blasting, grit is fired under high pressure against objects. The result is a clean, rough basis material that can be used for further surface treatment. Before the blasting process, vulnerable components such as rotating parts, propeller wire, and so on, are protected. Consideration about these parts is also taken during the blasting process. The blasting process is carried out in a blasting cabin. The whole process complies with the most stringent environmental demands.
