Frequently Asked Questions
What makes GreenCoat RWS more durable than standard steel rainwater systems?
GreenCoat RWS systems achieve superior durability through multiple technological advantages. All variants feature RC5 corrosion resistance classification (the highest available), double-sided coating protection, and specialized polymer coatings enhanced with PMMA (Plexiglass) particles for superior scratch resistance. The BT variants add bio-based coating technology that maintains or exceeds the performance of traditional coatings while improving environmental credentials. Additionally, the excellent UV resistance (up to Ruv5 in Pural BT) ensures color stability and surface integrity even after years of exposure to sunlight and weather elements.
How does the bio-based technology in BT variants work?
The Bio-Based Technology (BT) in GreenCoat RWS Pural BT and Pro BT variants represents a patented innovation that replaces a significant portion of traditional fossil-based coating components with Swedish rapeseed oil. This plant-based oil is integrated into the polymer matrix of the coating, maintaining or enhancing performance while reducing environmental impact. The technology results in a coating that offers excellent flexibility, durability, and scratch resistance while decreasing the carbon footprint of the product. SSAB holds worldwide patents on this technology, making it a unique offering in the construction materials market.
What is the expected lifespan of GreenCoat RWS systems?
While specific lifespans depend on environmental conditions and maintenance practices, GreenCoat RWS systems are engineered for exceptional longevity. With their RC5 corrosion resistance classification, high UV stability, and premium coating technology, these systems can be expected to perform reliably for decades. The highest-performing variant, GreenCoat RWS Pural BT, offers maximum durability with its combined corrosion resistance (RC5) and superior UV resistance (Ruv5). Regular maintenance, including annual cleaning and periodic inspection, can further extend the service life of these systems.
How do GreenCoat RWS systems contribute to sustainable building practices?
GreenCoat RWS systems support sustainable construction in multiple ways. The BT variants utilize Swedish rapeseed oil in their coatings, reducing dependency on fossil resources. All variants are completely chromate-free and REACH compliant, minimizing environmental impact during manufacturing. The steel itself is 100% recyclable, supporting circular economy principles. Additionally, the exceptional durability of these systems means fewer replacements over a building’s lifetime, reducing waste and resource consumption. These features align with SSAB’s broader sustainability roadmap, which includes goals for fossil-free steel production by 2026 and complete fossil-free operations by 2045.
Which GreenCoat RWS variant is best for extreme weather conditions?
For installations in extreme weather conditions, GreenCoat RWS Pural BT offers the highest level of performance. Its superior corrosion resistance (RC5) protects against moisture and atmospheric pollutants, while its exceptional UV resistance (Ruv5) ensures it maintains its integrity and appearance even with intense sun exposure. The bio-based coating technology provides excellent flexibility and formability, allowing the system to withstand thermal expansion and contraction through extreme temperature cycles. Additionally, its ability to be installed at temperatures as low as -15°C makes it ideal for cold-climate applications where other materials might become brittle or difficult to work with.
