With Permagrey, BWB Surface Technology presents an innovative colour range in elegant anthracite tones. With these timeless shades architectural visions can be individually realised preserving the aluminium's natural character. The exclusive Perma processes transform aluminium sheets into robust façades. The resulting surfaces withstand the harshest of weathering.
Colour shades (from left to right): Permagrey 1, Permagrey 2, Permagrey 3, Permagrey 4
Permagrey coating involves a controlled electrochemical oxidation process during which the base material's alloy elements are permanently integrated into the surfaces. The coating processes may be used for any formats and any shape of G77Ac aluminium sheet (the brand is not available for extruded profiles). Even large pieces up to 6.5 metres can be realised.
