Product Detail

PPGI is pre-painted galvanized steel, also known as pre-coated steel, color coated steel etc. Using Hot Dip Galvanized Steel Coil as the substrate, PPGI is made by first going through surface pretreatment, then the coating of one or more layers of liquid coating by roll coating, and finally baking and cooling. is pre-painted galvanized steel, also known as pre-coated steel, color coated steel etc. Using Hot Dip Galvanized Steel Coil as the substrate, PPGI is made by first going through surface pretreatment, then the coating of one or more layers of liquid coating by roll coating, and finally baking and cooling.

The term is an extension of GI which is a traditional abbreviation for Galvanized Iron. Today the term GI typically refers to essentially pure zinc (>99%) continuously hot dip coated steel, as opposed to batch dip processes. PPGI refers to factory pre-painted zinc coated steel, where the steel is painted before forming, as opposed to post painting which occurs after forming.

The hot dip metallic coating process is also used to manufacture steel sheet and coil with coatings of aluminium, or alloy coatings of zinc/aluminium, zinc/iron and zinc/aluminium/magnesium which may also be factory pre-painted. While GI may sometimes be used as a collective term for various hot dip metallic coated steels, it more precisely refers only to zinc coated steel. Similarly, PPGI may sometimes be used as a general term for a range of metallic coated steels that have been pre-painted, but more often refers more precisely to pre-painted zinc coated steel.

Coating Type

Polyester (PE): Good adhesion, rich colors, wide range in formability and outdoor durability, medium chemical resistance, and low cost.
Silicon modified polyester(SMP): Good abrasion resistance and heat resistance, as well as good external durability and chalking resistance, gloss retention, general flexibility, and medium cost.
High Durability Polyester(HDP): Excellent color retention and anti-ultraviolet performance, excellent outdoor durability and anti-pulverization, good paint film adhesion, rich color, excellent cost performance.
Polyvinylidene Fluoride(PVDF): Excellent color retention and UV resistance, excellent outdoor durability and chalking resistance, excellent solvent resistance, good moldability, stain resistance, limited color, and high cost.

 

Product features:

(1) Has good durability, corrosion resistance and galvanized steel compared with longer life;

(2) With good heat resistance, compared with galvanized steel plate, it is not easy to change color at high temperature;

(3) It has good thermal reflectivity;

(4) it has similar processing and spraying properties to galvanized steel plate;

(5) It has good welding performance.

(6) With good performance-to-price ratio, durable performance and very competitive price

What Is The Difference Between PPGI And PPGL Coil?

They are all based on cold-rolled steel sheets.

PPGI is pre-coated on cold-rolled steel sheets after galvanizing, and PPGL is pre-coated on cold-rolled steel sheets with an alloy of 55% aluminum and 43.4% zinc.

The density of 55% AL-Zn is lower than that of Zn, and it is more cost-effective to use galvalume materials than galvanized materials.

 

Chinese PPGL Coil Manufacturer Vs. Indian PPGL Coil Manufacturer

China’s hot-rolled steel coil production has accounted for more than half of the global hot-rolled steel output. In 2020, China’s hot-rolled steel output will actually account for 53.2%. In the same period, India’s hot-rolled steel coil production accounted for 5.6% of the world’s total output.
