Diamond, which is one of Pergoline Pergola Systems’ professional solutions, is a high technology awning system developed for large areas with a maximum opening up to 1200 cm without intermediate pillar. While it provides a shading service for large areas such as restaurants and hotels, Diamond is an innovative product with its central column-free, extra pillar-free feature. The product is resistant to the weights that it may encounter without the need of any support. Lateral areas can be closed with Vertiglass Automatic Glass Systems. In this way, open spaces can be easily converted to sheltered living spaces and winter gardens in line with the needs.
