Corrosion Protection

SSAB unveils GreenCoat RWS for corrosion resistance

GreenCoat RWS Pural BT … easy to maintain and cost effective throughout its lifecycle

To meet the global demand for sustainable and durable building materials, SSAB, a Nordic and US-based steel company, has widened its GreenCoat colour coated steel rainwater system product range by introducing GreenCoat RWS Pural BT which sports a matt appearance. It features a Bio-based Technology (BT) coating made with Swedish rapeseed oil, and is unique on the market.

“Climate is changing. An ordinary rain can result in 10 mm of rainfall in one hour. This adds up to 1 tonne of water on a 100 sq m large roof, demanding a durable rainwater system that can handle the strongest storms with the least maintenance – all while still looking amazing,” noted SSAB. 

GreenCoat RWS colour coated steels by SSAB provide beautiful aesthetics, superior quality and environmental benefits for any half-round and rectangular gutter system. They come in a wide range of almost 40 colours and can easily be matched with a GreenCoat roof to ensure a consistent look across the building.

According to the company, GreenCoat RWS products have a double-sided coating system that offers excellent protection against corrosion (RC5) and mechanical wear to withstand even the harshest weather. They also have high flexibility and formability, which allows them to be shaped in virtually any way.

Developed with partners

“The new GreenCoat RWS Pural BT is the result of an extensive product development collaboration involving consumer feedback, observing test results, and utilising the expertise of our partners,” said SSAB.

It provides excellent corrosion resistance (RC5), gloss retention and colour fastness reaching the highest class (Ruv5) according to updated EN 10169. The involved partners were: Piristeel (Finland), Galeco (Poland) and BILKA (Romania).


Sustainable building

Current building trends show that the demand for sustainable materials is on the rise. To address these growing trends globally, the new GreenCoat RWS Pural BT offers builders a level of sustainability found nowhere else on the market, featuring Swedish rapeseed oil in the coating. The result is a high performance, very formable and easy to maintain building product, SSAB said.

Steel is also one of the few materials that offers a 100 per cent closed recycling loop. This means that it can be used repeatedly and efficiently, without affecting its properties or performance – and without creating hazardous waste. Steel is easy to repurpose and reuse as well, making it a perfect choice for cost-efficient and durable rainwater systems.

“Sustainability plays an important role in the building industry. With our premium GreenCoat colour coated steels, we provide the most sustainable products with superior technical properties for the building industry,” said Olavi Huhtala, Executive Vice President SSAB Europe at SSAB Group.

GreenCoat RWS colour coated steels comply with current Reach regulations and are fully free of chromates, the company said. SSAB said it offers value added products and services developed in close cooperation with its customers to create a stronger, lighter and more sustainable world.
