Color Coating Line for Galvanized and Aluminum Coils

ALEKVS Color Coating Line | High-Performance Coil Coating System

What Is a Color Coating Line?

A Color Coating Line (CCL) is an advanced continuous processing system designed to apply organic coatings—such as polyester, SMP, HDP, or PVDF—on metal coil surfaces. Typically used on galvanized steel (GI), galvalume (GL), or aluminum coils, this line enables uniform, durable, and decorative color coatings, transforming raw metal into value-added pre-painted steel products (PPGI/PPGL).

At ALEKVS, we provide high-efficiency, automated Color Coating Lines engineered for precision, energy savings, and consistent quality—making us your trusted partner in premium coil coating technology.

Each ALEKVS CCL is engineered to deliver consistent surface performance through a precise series of treatments:

Uncoiling → Cleaning → Chemical Pretreatment → Primer Coating → Curing → Top Coating → Final Curing → Cooling → Recoiling

Detailed Process Breakdown:

Uncoiling: Uses a decoiler machine to load the metal coil and prepare it for continuous processing.
Cleaning Section: Removes oil, dirt, and oxide from the surface.
Chemical Pretreatment: Enhances paint adhesion and corrosion resistance.
Primer Coating: Applies a corrosion-resistant base coat (bottom/top side optional).
Curing Oven (1st): Heat-cures the primer for optimal bonding.
Top Coating: Applies the desired color and protective top coat.
Curing Oven (2nd): Final curing for a smooth, hardened finish.
Cooling & Tension Control: Brings coil to ambient temperature while managing shape and stress.
Recoiling: Coated coil is rolled and packaged for delivery or downstream use.
