Prepainted Galvalume steel Coil Manufacture

No cutting corners on quality and weight

Prepainted galvalume steel Coil(PPGL) Also known as color coated steel coil, is a type of sheet made of steel coil as the substrate, coated or laminated with various organic coatings or plastic films on the surface. Common substrates include cold-rolled sheets, galvanized sheets, galvalume sheets, high aluminum alloy sheets, and stainless steel sheets.

Production process: 

Surface pretreatment: Chemical degreasing and chemical conversion treatment are applied to the substrate to enhance the adhesion of the coating.
Application of organic coating: Apply one or more layers of organic coating on the surface of the substrate.
Baking curing: Bake the coated board to cure the coating.

Is that all? No！ We have more varieties

PPGL Steel Coil Surface Include The Following Types

	Smooth(Bright):  The surface is smooth and has a mirror effect, presenting a bright luster.
	Matte(Smooth):  The surface does not have a significant mirror effect, presenting a soft luster.
	Matte(Wrinkled):  The surface is treated with a matte finish, giving it a rough texture and presenting a delicate sugar like effect.
	Pattern:  The surface is embossed to present various patterns and textures, commonly including mesh, wood grain, stone grain, etc.

Please choose your favorite color and type according to your needs.

Prepainted galvalume steel coil

1.Lightweight texture: Due to its substrate being mostly metal coil, the overall weight is relatively light.
2.Corrosion resistant and durable: The surface coating has good corrosion resistance, which extends the service life of the board.

3.Good decorative properties: The surface can be coated with various colors of paint, suitable for different decorative needs.

Prepainted galvalume steel Sectional

Base Metal (Galvalume Steel): The core of the coil is galvalume steel, which is steel coated with a layer of aluzinc to provide corrosion resistance.
Chemical Treatment Layer: This layer is applied to the galvalume steel to improve adhesion of the subsequent coatings and to enhance corrosion resistance.
Primer Coating: A primer coating is applied on top of the chemical treatment layer. This layer further enhances adhesion and provides an additional barrier against corrosion.
Topcoat (Finish Coat): The topcoat is a colored paint layer that provides both aesthetic appeal and additional protection.
Back Coat (Optional): On the underside of the coil, a back coat may be applied.

Product quality inspection

	Width Test Check whether the width of the steel coil is consistent with the contract agreement, with an error not exceeding 1%
	Thickness Test Using sampling methods and machine detection of thickness for more accurate data
	Paint film thickness test Use the eight point test method to measure the thickness of the front and back paint film
	Impact resistance test Take samples of the color coated board and conduct impact testing to check for any peeling of the paint film

Silicone-Modified Polyester (SMP):Better weather resistance and color stability compared to standard polyester.
Polyvinylidene Fluoride (PVDF)Exceptional durability, chemical resistance, and color retention.

3.The price of prepainted galvalume steel coils?

the raw material of steel, 
the weight of Aluzinc of the galvalume substrate used,
the type of coatings used, 
the thickness of the top coat and back coat, 
the width and thickness of the steel coil to influence the price.

4.Does Pre-painted Galvalume Coil Have a Protective Film?

The protective film is a transparent or colored plastic film coated on the surface of the pre-painted galvalume steel coil. The purpose is to prevent scratches on the painted surface paint during cold roll forming.
Our plastic film thickness is 30 microns, 40 microns, 50 microns, 60 microns, and 80 microns.

5.Does the product have quality inspection before loading?

Of course, all our products are strictly tested for quality before packaging, and unqualified products will be destroyed.weaccept the third party inspection absolutely.

6.What product information do I need to provide?

You need to provide the grade, width, thickness, coating,color, and the number of tons you need to purchase.
