Coil covering, also known as pre-painted steel or pre-finished steel, refers to a metal substrate that has been coated with a protective paint layer and coiled in long strips. The most common base metal used for Coil Coatings is steel, but other metals like aluminum can also be coated. The protective paint applied acts as a shield against corrosion and other environmental damages. https://sanjanacmi.livepositively.com/coil-coatings-a-durable-and-sustainable-option-for-metal-building-products/new=1
