Products Description

Prepainted Galvanized Steel Sheet is also called PPGI. It is typically produced on a continuous galvanizing line (CGL). The CGL may include a painting section after the hot dip galvanising section, or more commonly the metallic coated substrate in coil form is processed on a separate continuous paint line (CPL). Metallic coated steel is cleaned, pre-treated, applied with various layers of organic coatings which can be paints, vinyl dispersions, or laminates. The continuous process used to apply these coatings is often referred to as Coil Coating.

Applications

Prepainted galvanized steel sheet is generally divided into four types: wave tile, trapezoidal tile, glazed tile and roof tile. According to the requirements of customers, we can produce different models, colors and tiles. Generally speaking, the application of wave tile and trapezoidal tile is widely used in construction, furniture and office equipments, agricultural equipments and other fields, it can be used to meet the paint used in specific terminals.

1Top coating: Cover the sun's rays and prevent UV from damaging the coating. The top coat can form a dense shielding film when it reaches the required thickness, and reduce the permeability of water and oxygen.

2Base coat: It is beneficial to strengthen the adhesion to the base material, which makes it not easy to remove the paint after the film is permeable, and also improves the corrosion resistance, because the primer contains corrosion resistant pigments, such as the luooate, passivating the anode and improving the corrosion resistance.

3A chemical film: It is mainly used to improve the adhesion between coating (galvanizing, aluminizing zinc) and coating (paint) with cold rolled plate. Different performance determines the performance of color board, such as strength

4Coating: generally galvanized or aluminized zinc, which has the greatest impact on the service life of the product.

5Cold-rolled sheet: use cold rolled plate, different performance determines the performance of color board, such as strength.

6Back coating: It is necessary to consider direct exposure on the back of color plate or use as a composite board. If it is used as a composite board, consider the adhesion property of the back paint and glue.


Advantages

Formability & Aesthetics:  Easy formability and bending property opens new horizons to the architect's  creativity. The wide range of colors provides options to the architect to customize requirements.


Convenience:  They are Economical as they require lighter supporting structure and also reduce transportation  costs. And they are virtually maintenance free.


Consistent Quality:  Ensures excellent performance in all weather conditions and hence enjoys trust &  confidence of millions.


Thermal efficiency:  Roofing Sheets & Cladding results in less heat radiation compared to other commonly  used roofing materials. Colouron when combined with insulation makes a cost effective, energy efficient roofing system.


Environment friendly:   Colouron galvanised steel has a long life and if eventually replaced are recyclable  without losing quality. The paint used to coat the base metal is also toxic free.
