There are many advantages with the keder system roof structures. The keder connection (where the individual panel is fed into aluminum track) produces no friction between the fabric panels and truss. Keder systems also allow for efficient and safe installation of fabric panels, in contrast to a single or two piece large stage covers. Typical panel width is 15 to 20 feet, which is an advantage when it comes to maintenance or repair/replacement of damaged fabric parts.
In essence, keder systems have the best fabric-to-frame fit and the longest possible working life span for the panels.
