RAL and DB colours are the most frequently used colours for coating windows, doors, curtain walls, sun protection, roller shutters or roller doors. heroal offers you more than 500 standard RAL and 20 standard DB colours for extruded profiles, for example for windows, doors, curtain walls and patio roofs. For roll-formed profiles, such as roller shutters and roller doors, heroal offers you a selection of colours. Additional shades of colour can be individually produced on demand. Not only is the well-thought-out choice of colour important for the desired effect, but also the gloss rate. It describes the directly reflected light: the higher the gloss, the more light is directly reflected. The RAL colours of heroal’s hwr powder coating are available with different gloss rates – ranging from dull mat through mat, brilliant and satin-gloss to metallic and speckled effects. Furthermore, the haptics of the surface can also be refined by a fine structure. In contrast to RAL colours, DB colours contain the effect pigment “hematite crystals” - these colours are predominantly used for steel components used for bridges or platform roofs.
