Centurion Tension Fabric Buildings

Centurion Tension Fabric Buildings are gable frame buildings optimized for projects requiring large usable envelopes and elevated clearances at the peak and the sidewall. A range of widths from 40′ (12.1 m) to 150′ (45.7 m) are available to meet the project specifications. The truss frame is forged from high carbon steel and reinforced with purlins and structural supports to meet the wind, snow, and dead loads required for each individual project. The continuous segmented truss design allows the building to achieve nearly any length required.

Build Bigger

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 Build Faster icon

Build Faster

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 Build Smarter icon

Build Smarter

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.

GNB Global made in the United States & Canada

Made In The United States & Canada

We proudly design, engineer, and fabricate our buildings with labor local to our manufacturing facilities in the United States and Canada.


Our trusses and steel components are manufactured from steel produced in American and Canadian refineries.


NovaShield® II, our primary HDPE membrane, is manufactured in Nova Scotia, Canada.

GNB Global tension fabric building steel fabrication


You won’t find cheap Chinese, mass-produced metal here. Our trusses and steel components are manufactured from American and Canadian-made, cold-formed seamless carbon steel that conforms to the ASTM A500 standard with a 50 ksi (345 MPa) minimum yield point. 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.

GNB Global tension fabric building membrane fabrication


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 Shadeshure® HDPE are available.

GNB Global tension fabric building foundations


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.
