Heritage 18 Tension Fabric Buildings
The Heritage 18 tension fabric buildings are optimized for mounting on concrete walls or shipping containers and are designed for low occupancy requirements. A range of widths from 30′ (9.1 m) to 55′ (16.7 m) are available to meet your exact needs. The continuous segmented truss design allows the building to achieve nearly any length required. Heritage 18 fabric buildings feature one-piece engineered fabric covers for easy installation. Our 18″ (45.7 cm) deep truss is forged from American and Canadian-produced, cold-formed carbon steel and reinforced with purlins and structural supports to meet the wind, snow, and dead loads required for each individual project.

GNB Global’s tension fabric buildings are the largest, most affordable clear span buildings available on the market today. Standard building widths are available up to a massive 150’ wide, with custom building widths available up to 400’ or more. The modular truss and fabric panel design of our buildings allows them to be built to accommodate any length required.
GNB Global fabric buildings are designed for simple and quick installation so builders can complete projects faster, and owners can occupy buildings up to 50-70% faster than conventional construction. Once a project begins, the site crew can prepare the building foundation while we simultaneously fabricate the structure at our manufacturing plant.
GNB Global’s tension fabric buildings are designed for versatility. Buildings can vary from simple open-end storage structures to fully enclosed, lined, insulated, and climate-controlled buildings. Smart features like our energy-saving translucent membrane that allows filtered daylight to light the interior sets the building apart from common steel buildings.

Our Give A Sh!t Guarantee
A warranty is only as good as the company that stands behind it. At GNB, we say as we do and do as we say. GNB’s fabric buildings are backed by our Give A Sh!t Guarantee, a comprehensive 16-year warranty, and fulfilled by our unbeatable customer service.
Our tension fabric structures are built to last – if something goes wrong, we are there to fix it right away. In addition to our 16-year warranties on each new fabric cover, our five-year Preventative Maintenance Program deal gives you rigorous annual inspections, a 25% discount, immediate repairs to anchorage and fabric issues, and increased longevity.
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.
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.
Other membrane options like HEYtex® PVC, Sheerfill® PTFE, and Polyfab Architec 400® HDPE are available.
A variety of tension fabric building foundation options are available to meet your specific building requirements and budget. Temporary foundations, often more cost-effective, are a good choice for situations where the building and foundation will be removed in the future, leaving no trace. Temporary foundations include Hogan stakes, duckbill anchors, helical anchors or screw piles, ballast blocks, rig mats, and shipping containers. Permanent foundation options include poured-in-place piers, grade beam, and poured slab foundations.
