Cantilever Shade Structures

Cantilever tensile fabric shade structures provide innovative and functional solutions for sun protection. They are lightweight, flexible, and durable and can be used for a variety of purposes, including shading walkways and covering large stadium arenas. These structures can cover the length of a sports pitch without blocking fans' views of the action. These structures are made by stretching and tensioning a fabric, usually PVDF-coated polyvinyl chloride (PVC) fabrics or PTFE-coated glass fiber fabrics or ETFE or STFE single layer/multi-layers foils, over a steel framework. The tensioning provides structural support to the membrane. They are versatile, durable, and quick to install. They can be used in a variety of shapes and sizes and are often cost-effective.
