Ideal composite material
Both PPGI and PPGL have the advantages of good formability, corrosion resistance, and strong adhesion. Even if used for a long time in bad weather, it can maintain its composition. These have become an ideal composite material in today’s construction, light industry, electromechanical products, and other industries.
PPGI uses galvanized steel as the basic steel and then paints it. The surface of the galvanized sheet is evenly distributed with a layer of zinc material. The alternative corrosion of the zinc material protects the use of the base material, and only when the zinc is corroded can it damage the inside.
PPGL is based on an aluminium-zinc plated substrate and then painted. The surface coating of aluminized zinc sheet comprises 55% aluminium, 43.5% zinc and a small number of other elements. The aluminium-zinc plate should be cut as little as possible. Once cut, the edge should be protected with anti-rust paint or zinc-rich paint to extend the life of the plate.
Finish
PPGI has a higher finish and looks more beautiful. PPGL steel coils have a higher finish than PPGI steel coils.
Corrosive
PPGL has higher corrosion resistance. If there are corrosion spots, the corrosion will spread on the PPGL board, but it will not spread on the PPGI board.
Price
Because the performance of PPGL is higher than PPGI, the price of PPGL is higher than PPGI.
Application
PPGI and PPGL can be used in are used in: daily necessities, housing and construction purposes
