The components for our buildings are manufactured from cold-formed seamless carbon steel structural tubing that conforms to the ASTM A500 standard with a 50 ksi (345 MPa) minimum yield point. The recycled content of the steel can vary depending on the source of available raw materials; on average there is 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, inline galvanized and powder coated to meet project specifications.
The standard architectural membrane material GNB Global employs is NovaShield® II with ArmorKote™, available with either a standard 4 mil coating or a 4 mil flame retardant coating. Alternate fabrics like PVC, Sheerfill® Architectural Membrane, and Shadeshure® are available for projects requiring those materials.
A huge benefit to the HDPE material GNB utilizes is the energy-efficient translucent qualities of the fabric. 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. Additionally, when electric lights are used near the fabric, light is reflected off the surface, amplifying the total lumens in the building.
NovaShield II with ArmorKote – RU88X-6 4 mil (standard)
Nova-Shield II RU88X-6 4 mil is a heavyweight fabric for applications requiring UV stability, such as membrane structures and alternate daily landfill covers. The scrim is produced in a special weaving pattern to enhance thickness, flatness, abrasion resistance, and tear properties. The proprietary coating is used to enhance abrasion resistance, flex resistance, seam strength, UV resistance and longevity.
This product meets the requirements of ASTM E84-00a (Class 1).
