K-style rainwater system

A K-style rainwater system gives a solid impression. The K-style rainwater systems are made using Finnish SSAB’s GreenCoat RWS Pural material in compliance with green values.

The benefits of the RWS Pural coating include outstanding corrosion resistance, good bending properties, durable appearance, good dirt repellent properties and ease of cleaning. The GreenCoat RWS Pural gives a trendy matt impression due to the micro-structure of the coating. This gives the products a finalized and dignified look.

Both sides of Piristeel gutter coils (both inside and outside the gutter) are coated with the thickest and most durable rainwater system paint coat in the market that is completely chromate-free and also meets the chemical requirements of the REACH regulation. GreenCoat RWS Pural holds the best possible rating for UV resistance (Ruv4) and corrosion resistance (RC5).
