    General Product Description

    GreenCoat Crown BT color coated steel is available in regular and matt finishes and offers a good range of colors inspired by Nordic nature. It uses a patented bio-based coating having Swedish rapeseed oil instead of traditional fossil oil in the paint, which is unique on the market. SSAB holds a worldwide patent for this coating technology (Bio-based Technology, BT).

    GreenCoat Crown BT offers a high level of durability for modular roofs and profiled roof tiles as well as for lock form roofs. It can also be used in sandwich panels for faҫades and wall claddings as it will keep its good look over time and stand up well against corrosion (RC5 class). The structured surface helps to protect against mechanical wear and is easy to handle during manufacturing.

    GreenCoat Crown BT color coated steel offers high gloss retention and color fastness. The matt coating delivers the highest level of color and gloss repeatability as well as a formability which makes the product a perfect choice for modular roofing applications.

    The reverse side of the sheet is painted with a two-layer grey backside coating.

    GreenCoat Crown BT complies with current REACH regulations and is fully chromate-free.

    SSAB’s color coated steels are all manufactured according to EN 10169.

      Comparison

        1) Excellent color and gloss repeatability for GreenCoat Crown BT matt colors is valid for different SSAB production batches produced during a half-year.

        2) Classification into corrosion resistance categories is based on blistering, delamination and damage on bend of the coating after two years exposure in natural outdoor testing sites as specified in EN 10169.

        3) Maximum steel thickness is 1.5 mm and maximum steel width depends on steel thickness. For other steel dimensions or steel grades please contact SSAB Tech Support.

        Note for Metallic colors: To ensure tonal consistency of colors on a single exterior face, all material must come from the same production batch. Also the directionality of surfaces has to be consistent especially when sheets are cut to size.

        Reverse Side Coating

        Unless otherwise specified, the reverse side of the sheet is painted with a two-layer coating to further improve the corrosion resistance of the end product. The coating provides good adhesion properties to many adhesives and foams; nevertheless the compatibility needs to be tested case-specifically.

            For easy material identification the reverse side of the sheet is stamped with the GreenCoat logo and the product name. The production year is marked to ease material traceability and can be referred to within the guarantee period. An arrow shows the direction of production to ensure installation in a uniform direction.
