COLOR COATED STEEL (PPGI/PPCR)

Royal Steel Color Coated Steel Sheet (PPGI/PPCR) has excellent corrosion resistance by using a combination of hot-dip galvanized and painted coating to create protective layers on the surface. Guaranteed by high aesthetics with many different colors to choose from, but still ensures and increases weather resistance as well as durability of the product.

RSC Color Coated Sheet is produced by coating on two sides of the sheet which consist a layer of epoxy and polyester finish. This creates a surface with high gloss, durable, not peeling and scratched during the cutting and corrugating process.

PRE-TREATMENT
PRE-TREATMENT
The steel strip is treated firstly in cleaning process, then applied with several chemical pre-treatments in preparation for paint coating. This process increases corrosion resistance and promote adhesion of paint.
ANNEALING AND PLATING
ANNEALING AND PLATING

After treated with chemical pre-treatments, a layer of primer is applied on the front side of strip. This layer enhances painting flexibility and adds an additional protection on corrosion. On the back side, depend on the customize, epoxy coating (wash coat) is commonly applied.

COOLING

Top coat then be applied on the primed surface, provides high aesthetic and color appearance with soft feeling of the surface, adding several additional features against weather impacts, UV rays, rust and corrosion.
