What is a fabric structure?

A fabric structure is a fabric membrane material stretched over steel trusses and is engineered to withstand wind loads, snow loads, and seismic conditions. Beyond being a more economical choice over conventional steel structures, fabric structures cost less to operate, save energy, provide natural lighting, are quick to install, and offer exceptional corrosive resistance while falling under the same requirements, codes, and certifications as any other steel building.

How long will the fabric cover last?

Non-Fire Resistant (Non-FR) fabric covers should last approximately 15-20 years under normal weather conditions, and 10-15 years for Fire Resistant (FR) fabric. Weather and ultraviolet radiation eventually wear down the material. While some rips and tears can be repaired, loose-fitting or worn fabric should be replaced. Fabric building owners may even want to recover fabric structures for aesthetic purposes to bring new life to pre-existing structures or to increase natural light.

What kind of fabric is used for the cover?

Calhoun uses both HDPE fabric and PVC fabric, and are available in a variety of colors. We also treat our fabric with ultraviolet stabilizers to protect it from the sun’s harsh UV rays. This prevents the fabric membranes from weakening due to the sun’s harsh rays, adding years to life for your fabric cover.

What happens if the fabric cover is damaged?

Calhoun’s local representatives can repair most damage that may occur to a fabric cover. To begin the process, we may ask to see photos, or do a site-visit, to gage the level of damage at hand. We also take into consideration the type of fabric cover system your structure currently has – either a Bag Cover system or a Keder Panel system – to determine the cost and turnaround time for fabric cover repair or replacement.

What fabric cover installation options does Calhoun offer?

Calhoun Super Structure offers two fabric cover installation options depending on the size and budget of your structure.

  1. Keder Panel System is a custom-made, individual strip of fabric mounted at each individual truss section. This system does not allow the fabric to touch the structure’s frame and helps to create a quieter, more secure environment with no risk of wear points on the cover – adding years of life to your structure. Calhoun’s Keder Panel system is standard on all buildings over 60′ wide.
    Key Advantage: Quick replacement of individual panels if damaged instead of having to remove the entire fabric cover
    Ideal For: HT series, VP series, larger CC series
  2. Bag Cover System is a large single-piece fabric cover that is tensioned both laterally and horizontally over the entire structure. This process is done quickly and easily in one single step.
    Key Advantage: Affordable and efficient installation
    Ideal For: Smaller CC series

What type of frames does Calhoun Super Structures use?

Calhoun Super Structure fabric buildings are engineered and manufactured using an open web truss, and hot dip galvanized for maximum corrosion resistance. Next to stainless steel, hot dip galvanizing is the best protection against rust and weathering.

For more information on our steel trusses, learn more here

How are Calhoun Super Structure fabric buildings protected from corrosion?

Every Calhoun Super Structure is hot dip galvanized according to long-established, well-accepted, and approved standards of ASTM, the Canadian Standards Association (CSA), and the American Association of State Highway and Transportation Officials (AASHTO).

These standards cover everything from minimum required coating thickness for various categories of galvanized items, to the composition of the zinc metal used in the process.

Hot dip galvanizing is commonly used in the most highly corrosive environments such as guardrails. The same long-lasting materials are used for your Calhoun fabric structure.

Can I customize my structure?

Yes. Calhoun designs, engineers, and manufactures your fabric structure to meet project-specific length, width, and height requirements which means that every structure is customized to fit your unique site location, application, and need.

We offer several end wall options, mount style options, fabric colors, and can build your fabric structure on different types of foundations. We customize our fabric buildings to meet your exact needs.

How do i know if a Fabric Building Manufacturer is of Certified Quality and Meets Buildling Codes?

Not all steel building manufacturers are certified CSA-A660 in Canada, and it’s easy to confuse ISO (and their certifications for quality management) with CSA-A660. The two certifications are not the same. ISO certification only verifies that a company can manufacture a product consistently and does not satisfy standard CSA-A660 requirements. The audit and certification requirements of CSA-A660 ensures that the manufacturer is complying with the applicable building codes and design standards, and that the purchaser is protected. You should always make sure that the fabric building manufacturer you choose is CSA-A660 certified in Canada and AWS certified in the United States. Calhoun Super Structure is both certified CSA-A660 in Canada and AWS certified in the United States.

What is CSA-A660 Certification?

From the Canadian Welding Bureau (CWB), the CSA-A660 Standard was developed at the request of the Canadian steel building system manufacturers, and provides assistance to code enforcement officials in the process of reviewing building permit submissions incorporating a steel building system, ensuring the purchasers obtain a quality building. All aspects of the manufacturer’s process goes through a meticulous audit including engineering design methods and personnel, materials control, fabrication, warehousing, packaging, shipping, erection documentation, and quality assurance. Because the manufacturer of these buildings is often remote from the building site, and local code enforcement officials may lack the capability to check the structural analysis of a building, problems may occur in determining the acceptability of such structures. It is the intent of CSA-A660 certification program to alleviate such problems. Calhoun Super Structure is both certified CSA-A660 in Canada and AWS certified in the United States.

What is AWS Certification?

In the United States, the AWS certifications set industry standards which help meet and maintain compliance for many project regulations. Certifications are built around the processes for different weld-types, and welders are then certified on those unique processes. Welders who have passed these certifications will have uniform outcomes, are knowledgeable about what can go wrong and why, and have proven that they have the skills to ensure good, secure welds. You can maximize confidence in the quality of your fabric structure project by working with fabrication shops who employ welders that are certified to the standards put forth by the American Welding Society (AWS). All of Calhoun Super Structure’s fabric buildings are AWS certified.

How much does a Calhoun Super Structure cost?

Calhoun Super Structure boasts a competitively-priced cost per square foot starting as low as $4 – $5 per square foot for a standard CC Series kit without end walls. For large-scale operations with ends, doors, foundation, and other accessories, you will want to budget approximately $15 – $20 per square foot. With a lower cost per square foot than most traditional structures, you enjoy an immediate cost savings right from the start. To learn more, visit our Quick Return on Investment page here.
