PPGL Steel Coil Description

PPGL is GL steel sheets coated with a colored paint layer.
Characteristics: PPGL provides enhanced corrosion  resistance along with a wide range of color choices. It is suitable for  architectural and industrial applications in harsh weather conditions.
Uses: Frequently used in the production of roofing, wall cladding, oil tanks, refrigeration equipment, and more.

PPGL  stands for pre-painted galvalume steel, which is a kind of color-coated  steel with GL as substrate. It combines the strength of steel with  excellent anti-corrosion of Zn-Al coating. The galvalume coating is made  of 55% aluminum, 43.4% zinc, and 1.6% silicon. Except for their  excellent corrosion resistance, PPGL sheets also have high thermal  reflectivity, which makes them heat-resisting.

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.
