Fabric buildings for warehouse and distribution centers utilize a tension membrane system where high-performance architectural fabric is stretched over a structural steel framework to create permanent or semi-permanent enclosed structures. The primary load-bearing system consists of hot-dipped galvanized steel or powder-coated steel rigid frames, typically spaced 20-30 feet on center, which support the main fabric membrane through a combination of purlins, girts, and cable tensioning systems. The fabric itself is engineered from PVC-coated polyester or PVDF-coated woven fabrics with tensile strengths ranging from 200-400 lbs/inch, providing a lightweight yet durable building envelope that weighs approximately 90% less than conventional construction materials.
