PPGI / PPGL

 

PPGI refers to pre - painted galvanized steel, and PPGL refers to pre - painted galvalume steel. Both are made by applying coatings after surface chemical treatment of the substrate.

 

●Key Advantages
PPGI: The galvanized layer provides good corrosion resistance. It has relatively low cost and excellent processing performance, allowing operations such as cutting and bending.
PPGL: The galvalume layer offers superior corrosion resistance, heat resistance, and reflectivity, with a long service life.

 

●Application Areas

PPGI: Commonly used for building roofs and walls, household appliance casings (e.g., refrigerators, washing machines), and some ordinary industrial products.
PPGL: Suitable for environments with high requirements for corrosion and heat resistance, such as the building envelopes of high - temperature workshops, equipment casings in the chemical industry, and water tanks of solar water heaters.
