Fabric Building FAQ

Fabric Finishing

What is a Legacy fabric building?
Legacy fabric buildings are clear span structures constructed using a rigid steel frame. Once the frame is erected in place, the fabric cover is connected to the frame using our proprietary process.

What type of fabric is used?
Legacy uses ExxoTec™ PVC fabric. To read more about our architectural fabric, click here.

Can Legacy buildings stand up to high UV exposure?
Yes. Our fabric is treated with UV stabilizers to help protect it from UV damage.

What colors of fabric are available?
ExxoTec™ fabric is available in a variety of colors. White and sandstone are popular options, but several other options are available.

Can fabric buildings be recycled?
In most cases architectural fabric cladding may be recycled.

What are some advantages of a tension fabric roof?

Tension fabric roofs have several advantages. Including:

  • In a corrosive environment, fabric will last longer and have a better warranty than a steel roof.
  • Inside a fabric building you’ll receive up to 70% of the natural daylight through the roof and walls, enhancing the interior environment.
  • Fabric is a non-conductive material, which will be cooler in the summer and warmer in the winter.
  • Fabric panels are cheaper and easier to replace than steel panels.

Rigid Steel Frames

What type of frame do Legacy buildings use?
Each structure is engineered and manufactured and on a solid web beam steel frame. Steel frames are available primed gray or red, painted any color, or hot dip galvanized for maximum corrosion resistance.

What is hot dip galvanizing?
There are two primary types of galvanizing: in-line (sometimes called “shielded”) and hot dip. Hot dip galvanizing is a better coating than shielded products because hot dip galvanizing applies 300% more zinc to all steel surfaces.

Hot dip galvanizing provides 3.9 mils of zinc on all surfaces. When other manufacturers weld to pre-galvanized products, the welding damages the outside of the zinc while creating a weld burn on the unprotected inside of the product. There is no way to protect the inside weld area from corrosion. Zinc protects steel by reacting with the environment instead of the steel. The more zinc available to protect the product, the longer the product will last, especially in a corrosive environment.

Hot dip galvanizing is commonly used in the most highly corrosive environments, including road sign posts, guardrails and cell phone towers. We use the same long-lasting materials for your building.



How may I customize my building?
Each Legacy building is custom designed and engineered to meet your project specifications. Large doors, uneven legs, lean-tos and more – we will customize the exact building to fit your needs.

How much do your buildings cost?
Each Legacy building is custom engineered and design-built to meet project specifications. The size and features of the building determine the cost.

What are your standard building sizes?
There is no standard size. We design and manufacture each building to meet project-specific length, width and height requirements.

What is the maximum width for your buildings?
We offer clear span designs over 300 feet wide. Buildings with interior columns are available any width.

What is the maximum length for your buildings?
Legacy buildings are available in any length.

What type of foundation does Legacy use for fabric buildings?
Our rigid frame structures can be built on most types of foundations. Lightweight fabric buildings may require a smaller foundation than other building types. Cast-in-place foundations, pre-cast concrete, panel foundations and other options are available.


Are engineered building prints available?
An engineer reviews all our building plans and provides the stamp on engineered prints. This engineer provides proof that the correct loading for the tension fabric building location and purpose were used to calculate the base plate reaction at the foundation. This procedure is necessary to ensure proper foundation design and to obtain building permits and insurance on the finished building.

How long do your buildings last?
All of our buildings come with a warranty. Depending upon your site location and the fabric selected, our covers should last 15-30 years or more. In most environments, the steel superstructure will last several generations.

Can Legacy design buildings for a heavy snow load?
Yes. We design buildings to meet or exceed local codes related to snow load, including roof snow loads of 30 pounds per square foot or more.

Do Legacy fabric buildings meet seismic building code requirements?
Yes. Our buildings are engineered to meet seismic requirements such as ASCE 7 and International Building Code (IBC).

Are your buildings designed for high wind speeds?
Yes. We design buildings to meet or exceed local wind speed requirements, including wind speeds over 100 mph (161 kph) and high velocity hurricane zones.

Are fabric buildings non-combustible?
No. However, Legacy’s flame-retardant fabric does meet NFPA 701, California State Fire Marshal and ASTM 84 building code requirements.

Are Legacy buildings portable?
All our buildings are designed as permanent structures, however they can be relocated or moved.

Are your buildings capable of being insulated?
Yes. Insulation up to R-30 is available.

Can my fabric building be climate controlled?
Yes. HVAC systems, insulation and ventilation can be added to the building frame.

Are your buildings permanent?
Our buildings are designed as permanent structures that are able to be moved if needed.


Do you install your buildings?

Yes. Our experienced crews travel to your location and construct the building from start to finish.

We offer two additional options for building installation.

  • A Technical Representative working with your contractor to install the building.
  • Legacy providing comprehensive plans and guidance for a local contractor to erect the building.

Are you able to service my Coverall building or a fabric building from another manufacturer?
Yes. Our staff has extensive experience with Coverall and other brand-name buildings. Contact us for answers about the value of your building, engineering reviews, maintenance questions or building repair.

How often do I have to tighten the fabric on my building?
You never have to tighten the fabric yourself. Your fabric building warranty requires you to visually inspect your building. If you notice problems with the fabric tension, Legacy will assess the problem and, if needed, repair the building at no cost to you.

May I eventually replace the fabric cladding with steel?
Our buildings are structurally designed for any type of sheeting; however, after experiencing the inside environment of a fabric building you won’t want to replace it with steel.

Do Legacy buildings corrode over time?
Fabric is ideal for use in corrosive environments, since it’s a naturally non-corrosive material. Steel frames are available hot dip galvanized for corrosion protection, or add a fabric liner to keep the steel out of contact with the corrosive material.

What happens if my building gets damaged?
Fabric buildings are easily repaired at a fraction of the cost of a steel building. Because our buildings are covered with individual fabric panels, our experienced crews replace or repair panels as needed.

If you have another brand of fabric building and are interested in a repair or a replacement, we may be able to help you. Contact us.

May fabric buildings be insured?
Yes. The steel frames are non-combustible, so the insurance rate is often lower than other building materials.

The Legacy Difference

What is Legacy’s Scope of Work?
In most situations, Legacy designs, manufactures, installs and services our fabric buildings. We also offer foundation engineering if needed. Concrete installation, permits, equipment and site installation are generally supplied locally. If preferred, we will partner with a general contractor in your area for complete building services.

Do you offer financing for your buildings?
Legacy will refer you to firms who are willing and able to finance our buildings.

Do you sell and service your buildings world-wide?
Yes. Legacy has customers in the US, Canada, Middle East, South America, Africa and Europe.

May I tour one of your buildings?
Contact us to learn if there is a building near you – we may be able to arrange a visit.

For a building walk-through, visit the video library or online photo gallery.

What makes your tensioning system better than other tension fabric structures?
Each fabric panel on a Legacy building is tensioned both horizontally and vertically. Each individual bay (frame-to-frame) contains a single kedered panel. We do not offer panels that “skip over” frames thus imparting unequal loads on different frames.
