Colmac Coil Manufacturing Inc., Colville, Wash., now offers hot-dip galvanized coils. Carbon steel coils that undergo a hot-dip galvanizing process experience longer life and require less maintenance because the entire coil surface is protected.

Due to the metallurgical bond between zinc and steel, galvanized coils typically are used in applications in which air and water are an issue. Galvanizing protects the steel from corrosion, rusting, shrinking and cracking in harsh industrial and other environments. For more information, go to
