PPGI Steel Coil Description

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.

Product Parameters

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.
