Colour Coated Roofing Sheet 0.6-1.2 MM

PPGI pre painted galvanised steel roofing sheets are metal sheets that are pre-coated with paint and zinc.The zinc coating, also known as galvanizing, protects the steel from rust and corrosion. PPGI sheets are primarily used as roofing for industrial and commercial construction projects. They can also be used for wall panels, door frames,and appliance housings. PPGI sheets have the corrosion resistance of galvanized steel, but they also have a customizable appearance.

Pre-painted steel is also less expensive than aluminum and is more resistant to corrosion and wear.The steel thus produced in this process is a pre-painted, prefinished and ready for further processing into finished products or components.

PPGI pre painted galvanised steel roofing sheets zinc coated steel substrate for PPGI is typically produced on continuous
galvanizing line (CGL). The CGL may include a painting section after the hot dip galvanising section,or more commonly the metallic coated substrate in coil form is processed on a separate continuous paint line (CPL).Metallic coated steel is cleaned, pre-treated, applied with various layers of organic coatings which can be paints, vinyl dispersions,or laminates.

The continuous process used to apply these coatings is often referred to as Coil Coating
