Fabric Structures and Temporary Warehouse Technical Specification
Unlike some of our competitors we use American made materials for our structures. Our fabric structures are constructed from some of the finest architectural fabrics available and meet or exceed NAFPA 701 (large & small scale) and California Fire Marshall requirements. Seams are radio frequency or hot air welded for water proof seams.
Fabric specifications
18 oz. PVC
We have used this PVC material for over 25 years. Unlike some of the newer thinner membranes made by foreign manufacturer’s this fabric has stood the test of time. We are proud to over this time tested material and stand behind it 100%. We can fabricate these covers in a multitude of patterns to create visually pleasing systems.
This material is in inventory in translucent white, opaque white, opaque green, and opaque tan. Translucent white allows a warm glow of light into the shelter. Opaque blocks all light from passing through the membrane (the fabric in the upper right on this page is opaque white).
22 oz. PV
This material is an upgrade to the 18 oz. PVC. It is made by the same manufacturer as our 18-oz fabric and the only difference is it is heaver, which means more abrasion resistant. This 22 oz. material is the material of choice where durability is the main priority.
28 oz. PVC
28 oz. PVC is the ultimate structure material. The backbone of this material is the proprietary polyester fiber weave that gives the material 700 lbs./inch grab tensile strength. This is the choice for consumers who demand the highest performance characteristics from their equipment. This is the standard material on our 150 ft. wide and larger spans. We would argue that this fabric is perhaps the finest fabric available today.
