Correctly formed fabric vaults

Arched Shade Structure
Arched Shade Structure

In order to be a correctly double curved “anti-clastic” surface, the fabric on an arched structure curves down between the arches as well as over the arch. To achieve this the fabric must be patterned with curved edges to each of the panels.

Often these structures are produced with straight fabric panel edges which results in a flat panel curved only in the one direction. These are produced by companies who do not understand the engineering principles or do not have the tools to pattern and produce these complex shapes.
