Exhibits excellent corrosion resistance even in marine environments or areas exposed to saltwater and seawater.
When thermal stimulus energy is applied to a material, atoms move within the material. This is due to the force that works to eliminate concentration gradients within solids and approach equilibrium. Based on this theory, the idea of coating steel with aluminum has been around for a long time, but the molten aluminum coating method was established in the United States in the 1930s. Research in this area had also been conducted in our country since before the war, but Shinko Aluma Co., Ltd. succeeded in establishing and commercializing the coating technology in 1953, and has continued to work on research and improvements to this day. The molten aluminum coating method of Shinko Aluma has been trademarked as "Alumer," and today it is commonly referred to by this name. For more details, please contact us or refer to our catalog.
