Printed color coated steel and aluminum coil

The printed color coated plate has decorative effects such as wood grain, brick grain, camouflage, marble, etc.

The printing color coated coils usually adopts the gravure printing process, which uses steel rollers for laser engraving of the required patterns to transfer the ink onto the surface of the steel plate.

• Firstly, the substrate is subjected to pre-treatment such as degreasing, cleaning, and passivation. After the pre-treatment process is completed, a layer of matching color primer is applied to the surface of the steel plate. According to the application field of the printed color coated plate, the primer can be divided into polyester, polyurethane, and other coating types. After the primer is dried and bakeout, printing is carried out using ink. According to the complexity of the pattern, it can be divided into single color printing and multi color printing. After the ink printing is dried and baked, Re-coating the varnish, including polyester, High durable polyester (HDP), fluorocarbon PVDF and other paint coating types. After the primer is dried and solidified, the entire production process of printed color coated boards is completed through processes such as cooling, coiling, and shearing.

• The above is a two-coating and two-baking production process, for the higher requirements of printing colour coated panels, such as fluorocarbon printing colour coated panels, you can use the three-coating and three-baking process, after the roller coating of polyurethane primer, then coated with a layer of fluorocarbon topcoat of the matching colours, and then ink printing, and then finally coated with a layer of fluorocarbon varnish.

Color coated aluminum sheet in coils has the characteristics of long service life, light weight, excellent surface effect and high recycling value, and has good economic benefits to meet the urgent demand of the current social economy and environmental protection development.

Our factory's aluminum color coating production line uses Germany's Siemens complete line control system, and the core painting process uses the world's most advanced German roll coating technology and twice-coated, twice-hot air-curing coating technology to accurately control coating thickness and curing quality.

The color aluminum adopts neutral treatment agent, roller coating treatment and hot air rapid drying process in the chemical treatment process, which is different from the ordinary dip coating chemical treatment method, which effectively eliminates environmental damage.

Moreover, the surface treatment is carried out with advanced chromium-free treatment liquid to meet strict environmental protection requirements at home and abroad.

During the curing process of the color coated aluminum plate surface coating'. the volatile components can be recycled and utilized for the second time, and equipped with an advanced VOC defluorination system to improve the utilization rate of heat energy while achieving zero emissions, and absolutely elimina te environmental pollution

Wooden Printed Galvalume Steel Coils Coating Types
According to different environment and uses, we can choose the different appropriate resin coating.
1) Polyester(PE)
