How Do I Choose the Right PPGI Steel Coil?
Prepainted galvanized steel coil is a kind of colour coated steel coil (PPGI coil). It uses galvanised steel as the base metal. The zinc layer is highly resistant to corrosion. Together with the coating, it is more durable than galvanised steel. The metal coated steel then undergoes a number of cleaning procedures, pre-treatment solutions and finally a multi-layer organic coating including laminates, vinyl dispersions and paint. This continuous technique of applying different coatings is known as coil coating. As a result, the steel coil is used in the finished product without the need for painting or finishing. PrePainted Galvanized Steel Coil (PPGI) and Pre-Painted Galvalume Steel Coil (PPGL) is a kind of building materials, with galvanized sheet and aluzinc sheet as the substrate, after pretreatment (degrease and chemical treatment) and liquid dope with several layers of color, then firing and cooling, finally the palte steel is called pre-painted galvanized steel coil (PPGI) o
