Color Coating Line (for Strip Steel)

The color coating line is one of our strip processing lines engineered for strip steel corrosion prevention purpose. On the coil coating line, colored paint is repeatedly applied to the galvanized and galvalume steel to produce a dazzling surface with enhanced corrosion-resistance. Major processes involved in this color coating line include degreasing, cleaning, painting, drying and curing.

Our patented color coating line creates a mix of benefits to appeal to customers. With this coil coating machine, a uniform coating, accurate coating thickness measurement accuracy, and reduced setup time can be achieved to ensure product quality and improve productivity.

Application Areas
As the name suggests, the major function of our color coating line is to place multiple layers of color paints onto the strip steel surface. Color-coated strip is highly malleable, corrosion-resistant, and mechanically strong. In addition to serving a utilitarian purpose, the plate also adds decorative glamour to the object due to its brilliant color. Recent years has seen its widespread use in construction, household appliance, and transportation industries as well as light industry.

Major Coil Processing Equipment for Composing the Strip Steel Color Coating Line

Roller Coater

In terms of driving mode, our roll coater adopts the independent drive manner. Each roll is separately equipped with a drive motor. As with this drive motor, the rotating direction and rotating speed can be changed within their allowable range.

Drying Oven

The industrial drying oven is comprised of oven body, internal ducting, cross-flow oven, air circulation fan, and external ducting. It promotes drying by efficient application of air re-circulated heat.
