PPGI is GI steel sheets coated with a colored paint layer.
Characteristics: PPGI steel sheets offer not only the corrosion resistance of galvanized steel but also a vibrant and customizable appearance. They are widely used in construction, manufacturing, and decorative applications.
Uses: Roofing, wall panels, door frames, appliance housings, etc.

The full form of PPGI is pre-painted galvanized iron. It is a kind of color coated steel or pre-painted steel, which is an extension of GI. As the name implies, it uses zinc-coated steel as substrate, and then it is cleaned, pre-treated, and applied with layers of coatings to make it more beautiful and durable to use. We adopt the coil coating process to make PPGI coils. With slitting, shearing, and roller equipment, we also have strips, plain and corrugated sheets for sale.

Surface Treatment
Laminated Film
The process is to coat a transparent organic film (30-50 µm) on the steel coil at high temperature. It has some unique properties, such as fire resistance, fingerprint resistance, excellent durability, anti-fouling ability, etc. Obviously, this treatment method can protect the steel coil well during storage and transportation.
Embossing
Embossed PPGI steel coil design has different patterns. Popular patterns are stucco, rhombus, etc. And it's customizable. Compared with the smooth steel coil, it has a vivid 3D effect.
 

Coating Type

In the coil coating, the durability of the role is the resin and pigment, the most commonly used finish polyester, silicon modified polyester, high durability polyester and polyvinylidene fluoride.
Polyester PE
Good adhesion, rich color, wide range in formability and outdoor durability, medium chemical resistance, low cost.
Silicon Modified Polyester SMP
The hardness, abrasion resistance and heat resistance of the coating film are good; as well as good external durability and powder resistance, gloss retention, general flexibility and medium cost.
High Durability Polyester HDP
Excellent color retention and UV resistance, excellent outdoor durability and chalking resistance, good 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 formability, dirt resistance, limited color, and high cost.
 

Scope of Application

Construction industry: such as roof, interior and exterior wall panels, balcony panels, suspended ceilings, partition walls, windows, door panels, etc.
Transportation: For example, car trim panels, train or ship decks, containers, etc.
Electrical equipment: mainly used for making freezers, washing machines, air conditioners and other enclosures. PPGI coils for home appliances have the best quality and the highest production requirements.
Furniture: such as wardrobes, lockers, radiators, lampshades, tables, beds, bookcases, shelves, etc.
Other industries: such as roller shutters, billboards, traffic signs, elevators, whiteboards, etc.
