The 
gutter system is made from Swedish PRELAQ® RWS (Rain Water System) steel supplied by the Swedish metallurgical concern SSAB.
SSAB Swedish Steel - the manufacturer of Prelaq RWS sheet metal - is the largest Swedish steel concern. The whole process of sheet metal manufacturing is integrated within the boundaries of a single company - from smelting steel, through rolling and galvanizing, to covering with organic lacquers. The steel is produced from an extremely pure ore of iron mined in the far north of Sweden.
Prelaq RWS is industrially manufactured in ideal conditions. Many layers, a thicker outer decorative layer, high flexibility, a durable surface and resistance to high temperatures - all that gives Prelaq RWS a greater lifespan, which results in lower costs.
The highest quality of the raw material guaranties the system's sturdiness, resistance to changing weather conditions and corrosion. Eight protective layers covering the sheet metal give perfect protection and many times extend the exploitation time of the system. The coating's technologically advanced structure provides for lasting colors for many years to come.
