Fabric Tension Buildings Provide Better Working Conditions


Maximum Light Transfer

G&B's Tension Fabric Building Covers, allow up to 80% of the natural light to enter your building. Whether you are working in a maintenance facility, training in a riding arena or stacking pallets in a warehouse, you’ll appreciate the natural lighting of a Portable Fabric Building. As an added benefit, you will save money during the day by eliminating the electrical costs of artificial lighting. At night, the fabric cover reflects light evenly throughout the building and reduces shadows.

Warmer in Winter and Cooler in Summer

Unlike metal clad and wood frame buildings, fabric structures do not conduct or radiate heat from sunlight into the building making it easier to maintain a constant temperature.

Fewer Drafts and Leaks

Tension fabric covers are virtually air and water tight unlike steel clad or post frame buildings.

Steel Truss Fabric Coverall Buildings are Cost Effective


Lower Purchase Price

Fabric Structures are often 20% less expensive than traditional buildings. Fabric over steel buildings are pre-engineered and prefabricated.


The Clear Span Fabric Building Design Adds More Usable Space

There are many cost effective foundation options from screw anchors to sea cans to moveable concrete blocks. G&B’s certified installation crews will have your building safely and professionally installed in no time.

Clearspan Buildings & Structures Add Usable Space

Clearspan Fabric Buildings

The unique Hoop Building and Hoop Barn Designs with portable fabric covers give you a totally unobstructed floor space up to 200’ across or more. This is ideal for event centres, riding arenas and commodity storage.

Prefabricated Canvas Covered Buildings are Portable & Resalable


Easily Portable Between Locations

While most are intended as permanent structures, the unique design of fabric over steel buildings allows you to easily and economically transport them to another location. Smaller structures can be moved by crane while others can be disassembled, repackaged and shipped. This makes your structure an asset that can be sold when it is no longer needed or when it’s time for an updated facility.

Portable Fabric Buildings Have Low Operating Costs


Low Maintenance

The Fabric Hoop Building design is highly resistant to rust and corrosion. The coated fabric is resistant to dirt and mildew and is self-cleaning in the rain. Maintaining the proper tension on the fabric will keep your building looking like new. G&B also offers a comprehensive maintenance program to get maximum life and performance from your fabric structure.


Inexpensive Repairs

The unique design of fabric over steel buildings allow for simple minor repairs which can be done by the owner on-site.

Steel Truss Fabric Covered Buildings Support A Healthy Workplace Environment


At Work and Play


Portable Fabric Buildings have larger air volumes due to the high dome. Exhaust fumes rise and clear through the building’s vents. Natural lighting also contributes to a more comfortable environment.


In the Dairy Barn or Horse Stable

Fresher air and natural light results in happier animals with more even characters. In dairy barns, the addition of more natural light increases milk production. Breeding cycles are also more even and consistent.

Fabric Buildings Withstand Higher Snow and Wind Loads

Hoop Building Design

The Fabric Tension Over Steel Building receives additional strength from the half round dome design. The polyethylene fabric offers a virtually friction free surface preventing the build-up of any appreciable snow load. It has the added benefit of being self-cleaning in the rain. Both steel clad and post frame structures require more trusses and cross supports to manage the same loads which drives up their cost.
