For decades, the name of Robering has been synonymous with profiles that stand out for their exceptional quality. Thanks to almost 60 years of experience in the field of profiles, we are not only able to provide this high standard, but are also in a position to use our expertise and innovation to realise new ideas for profiles. We no longer stock window transoms with white lips and black adhesive strip as standard. These combinations are manufactured as required in a special production process with corresponding delivery times. Due to the fact that the profile systems tend to use the colour RAL 9016 Traffic white, the colours RAL 9010 Pure white and RAL 9003 Signal white have become special colours that we no longer stock on site. However, we can of course still produce these colours according to customers' wishes. We produce our standard profiles using only newly produced hard and soft PVC materials (we do not use recycling-grade materials).
