A sophisticated system based on the modular design principle, which allows for roofings and weather protection structures. It consists of the following main components:
Ridge girders, roof girders of various lengths, longitudinal and diagonal ledgers, eave bracings, keder tarpaulin covers, girder supports, optional head struts and a manageable number of accessories
The "centrepiece" of the roofing system is the three-chord aluminium lattice girder, which is based on the structural system of a two-hinged frame. The design focus is on the multi-track keder profile. Due to the two keder tracks on either side, any span width can be implemented using Keder tarpaulins of only three standard sizes since the tarpaulin installation can be overlapping.
