Tension Fabric Building Materials
Steel
You won’t find cheap Chinese, mass-produced metal here. Our trusses and steel components are manufactured from American and Canadian-produced, cold-formed seamless carbon steel that conforms to the ASTM A500 standard with a 50 ksi (345 MPa) minimum yield point. The recycled content of the steel varies depending on the source of available raw materials. On average, our steel is composed of 57% Post-Consumer Recycled Content and 31% Pre-Consumer Recycled content.
Our fabricated steel truss components can be finished in a selection of coatings, including hot dip galvanized and powder coated to meet your project specifications.
Membrane
The standard architectural membrane material GNB Global employs is NovaShield® II with ArmorKote™, a Cradle to Cradle certified product. The membrane is available in several colors with either a standard 4 mil coating or a 4 mil flame retardant coating. The NovaShield scrim is produced in a special weaving pattern to enhance thickness, flatness, abrasion resistance, and tear properties. The proprietary coating improves abrasion resistance, flex resistance, seam strength, UV resistance, and longevity.
Its energy-efficient translucent qualities make the HDPE membrane ideal for our buildings. White and lighter-colored membrane materials allow around 12% of filtered sunlight to transfer through the translucent fabric, reducing the need for electrical lighting during daylight hours. When lights are used near the membrane, the light is reflected off the surface, amplifying the total lumens in the building.
Other membrane options like HEYtex® PVC, Sheerfill® PTFE, and Polyfab Architec 400® HDPE are available.
