Tension fabric building on a rigid steel frame

Legacy was the first to engineer custom tension fabric structures on solid steel frames for all industries and uses. We offer complete customization and full-construction services for durable, safe buildings with an unrelenting focus on quality and value.

Rigid steel frames allow the construction of larger clear span buildings. Strong steel frames allow hanging loads such as conveyors, cranes, and overhead doors including MegaDoors and oversized doors. Optional hot dip galvanized (HDG) frames prevent oxidation in corrosive environments.


We are a full-service, turnkey fabric building construction firm, specializing in design-build or engineer-procure-construct (EPC) project delivery. This building philosophy results in greater quality control and expedited project schedules.

Fabric buildings by Legacy are designed and engineered to meet precise project specifications. Customization and accessories are virtually unlimited. For example, eave extensions direct moisture away from the building and create soffits for passive ventilation. Eaves with icebreakers create a safe, dry corridor near the building. Active and passive ventilation systems, climate control, safety management systems, sprinklers and lightning suppression are just some of the additional features available for your tension membrane structure.


Legacy fabric structures are far sturdier, longer lasting, and more conventional looking than hoop buildings, Quonset huts, air-supported “bubble” buildings, Cover-All buildings, tensile buildings, sports domes and tents. After observing the weaknesses in other fabric buildings, our innovative team created the proprietary attachment system that allows fabric skins to be attached to a rigid steel frame for the first time.

There are no limits to the uses of fabric covered buildings. Popular applications include cold storage, supply chain and manufacturing. Clear-span buildings with straight side walls, flexible foundations, optional insulation and HVAC climate control, and varying roof pitches create the perfect environment for gaming, retail and entertainment venues, fabrication, public works, petroleum production, transload facilities and more.


Our in-house construction crews have worldwide experience installing tension fabric buildings. We have partner offices in Edmonton, Alberta; Chile, Sudamerica; and Turkey. Legacy buildings can be seen in Saskatchewan, Alberta (AB) and other provinces such as British Columbia (BC), Manitoba, Ontario, Quebec, Newfoundland and Labrador, Nova Scotia and New Brunswick. In South America, buildings are in Peru, Bolivia and Ecuador. Europe; Nigeria, Africa; and Oceania are also home to fabric structures. Engineered fabric buildings are adaptable to any site or weather conditions, even the extreme cold of the Arctic Circle.

Architectural fabric membranes made of polyethylene (PE) or polyvinyl chloride (PVC) create a naturally bright interior and are inherently non-corrosive. Although each structure is designed as a permanent, high-quality solution with flexible foundation options, lightweight fabric covers are easy to roll up, making the buildings relocatable and portable when necessary. PE and PVC can be recycled where facilities exist, and flame-retardant (FR) fabric cladding is available. Additionally, fabric buildings install faster and safer than structures made of steel sheeting – and with less construction waste. With our quick, efficient construction process, your frame-supported fabric building may be installed in as little as one week.

A Fabric Building For Every Industry

The design-build construction process takes all the pressure off you. As a contractor, Legacy’s scope of work includes the engineering, design, installation and maintenance of each fabric building we sell. In-house building engineers and installation crews take your project specs and drive the entire process from start to completion.

And, of course, the buildings themselves are flexible enough to meet any needs. The hot dip galvanized steel frame prevents oxidation. A primed, powder-coated or painted steel frame is another good option for non-corrosive storage and environments. Wide bays and clear-span design accommodate any vehicles or aircraft. Straight side walls create more interior space. Check out some of our fabric building pictures and case studies to see what we’ve done and inspire new ideas for your application.

Each building is supported with a time-tested I-beam frame, while architectural fabric creates easy daylighting or daylight harvesting – an uninsulated building has up to 12% translucency. Our customers consistently report saving on energy costs, and people and livestock inside the structure enjoy the more natural environment.

As a non-conductive building material, fabric buildings better maintain a comfortable inside atmosphere year-round. The interior of an energy-efficient fabric building is up to 20 degrees cooler in the summer and about 10 degrees warmer in the winter, even before the addition of HVAC systems or insulation.

Solid web I-beams have less surface area exposed to the elements than hollow-tube web truss systems, which are vulnerable to rust formation in the unseen space inside the tube. The steel superstructure, plus all steel members, can be hot dip galvanized for the ultimate corrosion protection. Unlike in-line galvanized or shielded steel, hot dip galvanized steel has a continuous layer of zinc defending the steel substructure from corrosion.

For especially corrosive environments such as fertilizer storage, frac sand storage, mining products storage and wastewater management, adding a secondary or interior fabric liner keeps all steel members out of contact with corrosive elements and materials. An interior liner adds years to the life of the fabric structure.

Our unique attachment system creates a weather-tight seal and a dry, useable building envelope. There are no protrusions to allow moisture in, and no chance of rust eventually eating through the building and causing leaks.

Ventilation options include mesh wall vents, eave vents, open ridges, peak intake/exhaust valves, and more. A ventilated fabric building keeps stored materials such as grain or corn dry and cool. Popular ventilation options for cattle barns include open side walls to allow continuous airflow throughout the building. Custom engineering makes any wall configuration open for a dry, healthy environment for your livestock and feedbed.

Custom fabric structures adhere to the same engineering codes ASCE7, ASCE 55-10 and building codes as other types of structures. Other construction blue book classifications are Division 13 – Special Construction including 133100 Fabric Structures, 130130 Operation and Maintenance of Special Structures, 133000.00.01 Special Structures, 133123 Tensioned Fabric Structures, 133133 Framed Fabric Structures. Some fabric building manufacturers count on the tensioned fabric cover to make up for deficiencies in an inferior structural design. At Legacy, we rely on time-tested engineering, purlins and other structural elements to add legitimate strength and stability to our fabric structure designs.
