Charcoal RAL7024 Wirinkle Steel PVDF PPGl G90=Z275 Textured Matt Pre Painted Galvanized Steel Roof Sheets

Introduction: 

Colour coated coil is a product made from hot-dip galvanised sheet, hot-dip aluminium zinc plated sheet, electro galvanised sheet, etc., which is pre-treated (chemical degreasing and chemical conversion treatment) and then coated with one or several layers of organic paint and subsequently baked and cured. Because of the coating of different colours of organic paint coloured steel coil and so named, referred to as colour coated coil.

The use of hot-dip galvanised steel strip as the substrate of the colour coated steel strip in addition to the zinc layer protection, the zinc layer on the organic coating plays a role in covering and protecting the steel strip to prevent rust, the service life of the steel strip is longer than the galvanised strip, about 1.5 times. 

​

• Classified by substrate type, organic coated steel plates typically use cold rolled sheets, hot galvanized sheets, electro-galvanized sheets, alloyed plates, galvanized aluminum plates, galvanized zinc alloy plates, tin plates, chrome plates, aluminum plates, and others.
•  
• Classified by processing technology, the different coating methods include roller coating, spraying, powder coating, composite film, and printing. Depending on the number of coating and baking cycles, there are single coating and baking, double coating and baking, triple coating and baking, and quadruple coating and baking processes. These processes produce various types of organic coated steel. Additionally, based on embossing or printing, they can be further subdivided into wood grain, marble grain, leather grain, and cement mortar grain coated steel plates.
•  
• Classified by coating type, organic coatings can be made with different paints, resulting in PVC coated steel, polyester coated steel, acrylic coated steel, fluorocarbon coated steel, and silicone polyester coated steel.
•  
• Classified by coating performance, there are high weather resistance coating plates, high temperature coating plates, self-extinguishing coating plates, sterilization coating plates, non-stick snow coating plates, fingerprint-resistant coating plates, and self-lubricating coating plates.
•  
• Classified by special coatings and uses, there are epoxy zinc-rich coatings, cold rolled steel substrate organic coatings, surface flocked steel, and special machine-coated laminates, such as post-wood film boards, sandwich panels, and shock-resistant boards.

Colour Coated Coil Usage: 

Colour coated coil has light weight, beautiful and good anti-corrosion properties, and can be directly processed, the colour is generally divided into grey and white, sea blue, brick red, mainly used in advertising, construction, home appliance industry, electrical appliances industry, furniture industry and transport industry.

The coatings used for colour coated rolls are selected according to the use of different environments with suitable resins, such as polyester silicone modified polyester, polyvinyl chloride plastisol, polyvinylidene chloride and so on. Users can choose according to the use.

Coating Structures: 

Type of coating structure

2/1: Coat upper surface twice, lower surface once, bake twice.

2/1M: Coat upper and lower surfaces twice, bake once.

2/2: Top and bottom surfaces are coated twice each and baked twice.

Usage of different coating structures:

Colour Coated Coil Coating Types: 

1. Polyester Offers good adhesion, vibrant colors, a wide range of formability, and outdoor durability. It has medium chemical resistance and is low cost.
