Color Coated Prepainted Galvanized Steel Coils (PPGI Sheet) Supplier In UAE, Oman, And Saudi Arabia

The prepainted steel sheet is a material that is obtained by subjection to chemical treatment (coating) followed by reheating and cured by a hot-dipped galvanized steel sheet or a sheet of aluminum. A hot-dip zinc-coated thin-film sheet of PPGI sheet is also known as the pre-painted galvanized steel coil and color coated steel coil.

• The cumulative thickness is composed of the base steel – coating – primer – top paint – protective layer thickness of the pre-painted galvanized steel coil. The top layer is 10-25 μm thick, and the back layer is 5-20 μm thick. The thinner the thickness of the base steel, the higher the PPGI steel coil price, as the manufacturing costs are increasing.
• Polyester (PE) is typically used as a layer or white grey paint coating material. The color may be modified to the color card or client samples of the RAL. It is useful to create unique patterns like wood grain, floral print, camouflage, and stone.

Types of Color Coated Steel Coil

Matt PPGI

The matt PPGI Coil includes large and small wrinkled PPGI. The thickness of the paint coating is 20μm-45μm, which is not easy to colorize for roofing sheets with longer life.

Steel Sheet in Coil Prepainted with Brick Designs

The pattern of bricks is printed on a sheet of galvanized steel.

Application: Inner walls, outer decorations.

Coated Coil with Marble Color

A galvanized sheet is printed with the marble pattern.

Application: Inside and outside walls

Steel Coil with Camouflage Color

Printing patterns of camouflage on galvanized sheets or Aluzinc sheets.

Application: Inside and outside walls

Prepainted Steel Coil with Wooden Design

On galvanized or Aluzinc sheets, print patterns of wood grain designs.

Applications: Garage and house doors

The Process to Produce PPGI Coil

The process to produce such coils are baking, cool down, fine coating, engraved film, export loop, inspection plant, cut, coiling, stitch with machine, entry, preprocessing, initial coating, bake, etc.

If the cleaning degreasing process is not well handled, the binding of the primer to the galvanized sheet of a color-coated sheet cannot be pleasant. During the press forming process, it is easy to decompose the topcoat of the color-coated steel coil.

Coating Types

The present coating types for PPGI / PPGL coil available are PE, PVDF, SMP, acrylic, PVC, etc.

PE

Because of its strong adhesion, the PE coated stainless steel sheet is easy to process, shape, and the price is comparatively inexpensive. However, the other degree of resistance to UV and cracking is relatively poor. The roof of ordinary civil buildings can be fitted with PE color-coated steel.

SMP

The reliability of the SMP steel frame is higher than that of PE. In terms of adherence and formability to materials, silicone is not as strong as PE.

High durable Polyester or HDP

The outdoor weather resistance is 16 years greater than the ordinary SMP coatings. Its weather tolerance and flexibility are much higher.

PVC

PVC coating has great anti-chemical and anti-water and is very dense and can protect the substance properly. The PVC coating is hardly used because of chemical exposure.

PVDF

The color preservation and corrosion resistance are excellent for PVDF coatings. It is the highest grade of the PPGI sheet coating for constructing buildings.

Acrylic

The overall performance is great, the price is high, and is used only in some fields (such as containers).

The selection of a pre-painted galvanized steel coil must take into account its natural environment, its application, its nature, and structural characteristics in order to meet its suitable steel grade, metal coating, characteristics, and coating requirements.

The results of a steel sheet are mainly based on mechanical properties (stress, tensile stress, elongation), the metallic coating efficiency (a type of metal coating, thickness, and bonding), and performance of the coating method (coating species, color, gloss, durability, processability, etc.)

The wind and snow and caustic climate are the key factors of the selection of color-coated steel sheets in various areas.
