Specification:

Pre-painted Galvanized steel is a Galvanized steel with a number of paint layers and treatments in a carefully controlled environment in a continuous coil coating line.
Pre-painting can also be done on electrogalvanized coils and cold rolled coils depending on the end-use and application of the steel.

PPGI Steel Coil is better at corrosion resistance. Paint on hot dip galvanized steel make it decaorative and usually used to indoor and outdoor decoration. Service life of PPGI coils can up to 20 years without fading.(Zn 60g, 25um painted in top and 10um painted in back).Production meets the standard of EN10147 DX51D+Z, JIS G3312 CGCC, ASTM A755M A653M.

We are a PPGI & PPGL manufacturer/supplier in Shandong, China. Our PPGI (Prepainted Galvanized Steel) & PPGL (Prepainted Galvalume Steel) are available in a variety of specifications.

We could also provide the product life length lasts for decades as customers commanded.

• PPGI Coil or Pre Painted Galvanized Sheet Coils are basically zinc coated steel sheets which are further treated with organic coatings and finally paint coating and hence are termed as Pre Painted. Available in all colors on order.
