kuumasinkitylle

Kuumasinkitys is a Finnish term referring to the process of hot-dip galvanizing. This is a method of applying a protective zinc coating to steel or iron to prevent rust and corrosion. The process involves immersing the fabricated metal into a bath of molten zinc. Before dipping, the metal is cleaned to remove impurities, typically through a degreasing and acid pickling process, followed by a fluxing stage to ensure good adhesion of the zinc.

Once immersed, the molten zinc metallurgically bonds with the base metal, forming a durable, multi-layered coating. This coating provides both barrier protection, physically separating the steel from corrosive elements, and sacrificial protection, where the zinc corrodes preferentially over the steel. The thickness and uniformity of the coating depend on factors such as the composition of the base metal, the temperature of the zinc bath, and the immersion time. Kuumasinkitys is widely used for protecting structural steel, fencing, automotive parts, and various other metal components exposed to environmental conditions. It is a cost-effective and long-lasting method for enhancing the lifespan of steel products.
