PPGL (pre-painted galvalume) sheets are high-quality roofing and cladding materials made from a combination of galvanized steel and aluminum. A thick layer of paint or other protective materials coats these sheets to enhance their durability, aesthetics, and resistance to corrosion. Galvalume is a coating consisting of zinc, aluminum and silicon that is used to protect a metal (primarily steel) from oxidation. It is similar to galvanizing in that it is a sacrificial metal coating which protects the base metal. One of the most significant advantages of PPGL sheets is their durability. They last for several years, and their maintenance remains minimal. It happens because of the galvalume coating that provides excellent protection against rust and corrosion, while the paint layer adds an extra protection layer against nature’s harshest elements. As such, PPGL sheets become ideal for people planning to install low-maintenance roofing or cladding solutions.
PPGI is pre-painted galvanised iron, also known as pre-coated steel, coil coated steel, color coated steel etc., typically with a hot dip zinc coated steel substrate. The term is an extension of GI which is a traditional abbreviation for Galvanized Iron. PPGI is used in construction for manufacturing roofing sheets, roofing tiles, walls, doors and windows, partitions, panels, louvers, slotted angles and valley gutters. The most common application of Pre-painted Galvanized Iron (PPGI) is the construction industry. Metal sheets - Metal roofing sheets like steel and aluminum are durable, long-lasting, and can withstand extreme weather conditions. They are lightweight, fire-resistant, and energy-efficient, making them an excellent choice for residential and commercial roofing.
