What Are MegaDome Fabric Buildings?
MegaDome Fabric buildings are modern, cost-effective structures made with a steel truss frame and a durable, tensioned fabric membrane. They offer a flexible, long-lasting alternative to traditional wood or metal buildings and are ideal for agricultural, industrial, and municipal applications.
MegaDome fabric buildings are engineered and manufactured in Canada to handle even the harshest environments. Our steel truss frames—the backbone of every structure—are available in two roof profiles: a classic peaked roof or an elegant arch profile. These options allow you to choose the shape that best fits your operational needs.
Key Features & Benefits:
- Available with peaked or arched steel truss frames
- Double truss
- Lower cost per square foot (starting at $15/sqft)
- 15-year structural warranty
- Customizable sizes and layouts
- Fast installation and easy relocation
- Naturally bright interiors with daylight-diffusing fabric
- Designed for durability and minimal maintenance
Discover how MegaDome fabric buildings deliver the strength of steel and the efficiency of fabric—engineered to perform, built to last.
Why Choose fabric building as a solution for warehouse and storage
If you’re considering a low cost tension fabric building for your next project, it’s time to look at MegaDome. Unlike generic conventional structures, MegaDome fabric buildings are engineered in-house, built to meet your region’s building codes, and designed for maximum lifespan and performance. We offer stamped engineering, exclusive oval steel tubing, and hot-dip galvanized components—advantages most legacy Coverall-type companies don’t provide.
3 Potential Uses of Fabric Buildings
MegaDome® Fabric Buildings offer exceptional versatility across a wide range of industries. In agriculture, they are commonly used for equipment and machinery storage, hay and grain protection, livestock barn, and horse riding arenas. Their spacious interiors and natural light make them ideal for maintaining healthy animals and efficient operations. In the industrial sector, fabric structures serve as warehouses, bulk material storage facilities, maintenance shops, and even remote mining site shelters, thanks to their rapid installation and portability.
Municipalities and government organizations use canvas buildings for public works equipment storage, recycling centers, emergency response shelters, and fleet garages. Their cost-efficiency and durability make them a smart choice for year-round utility. Commercial and institutional applications include event venues, sports facilities, industrial storage, and aviation hangars—offering scalable space with minimal maintenance.
With their engineered steel truss frames, available in both peaked and arch profiles, and starting at just $15/sqft, MegaDome Fabric Buildings provide a reliable, adaptable, and long-lasting solution for nearly any environment or operational need.
Components Used & Their Benefits
MegaDome Fabric Buildings are designed using premium materials engineered to withstand Canada’s harshest conditions. At the core of each structure is a high-quality polyethylene fabric welded in our manufacturing facility under strict quality standards. This membrane is not only durable but also tear-proof—in the event of a puncture, the damage will not continue to spread. Minor repairs can be quickly and easily made using patch tape or by welding on a new piece of fabric, ensuring long-term durability and cost-effective maintenance.
Our steel truss frames—available in either a peaked or arch profile—can be manufactured from oval structural steel for added strength and visual appeal. To protect against corrosion, the steel components are hot-dip galvanized. They can also receive an epoxy coating for enhanced resistance in aggressive environments, such as salt storage or high-humidity agricultural settings.
The fabric cladding creates a naturally bright and energy-efficient interior. The translucent material allows soft, diffused daylight to enter, reducing the need for artificial lighting. This breathable environment helps regulate temperature, typically keeping the interior up to 10°C cooler in summer and 10°C warmer in winter—without the need for mechanical heating or cooling. For projects requiring controlled environments, insulation and HVAC systems can be integrated as needed to ensure optimal conditions.
We also offer an exclusive Canadian agricultural membrane that allows approximately 30% light transmission, creating an optimal environment for livestock, equipment, or crop storage. This specialized membrane enhances animal comfort, reduces stress, and promotes productivity, making it an ideal choice for farm operations nationwide.
Benefits of Canvas Buildings by MegaDome
MegaDome® Canvas Buildings offer a unique combination of strength, flexibility, and efficiency, making them an excellent alternative to traditional structures. One of the most significant benefits is their cost-effectiveness—with prices starting as low as $15 per square foot, fabric buildings provide large, functional spaces at a fraction of the cost of conventional construction.
These buildings are designed for rapid installation, allowing you to have a fully operational facility in weeks instead of months. Their modular design also allows for easy expansion, relocation, or reconfiguration as your needs evolve or as a temporary shelter.
Another significant advantage is the natural light provided by the translucent fabric cladding. This reduces the need for artificial lighting, lowers energy costs, and creates a more comfortable and productive environment for both people and animals. Additionally, fabric buildings are naturally energy-efficient, often maintaining interior temperatures that are cooler in summer and warmer in winter—without relying on active climate control systems.
Built with galvanized steel trusses and tear-resistant polyethylene fabric, MegaDome® fabric buildings are engineered to withstand harsh weather conditions, including heavy snow, high winds, and extreme temperatures. Optional coatings, such as epoxy, can further enhance corrosion resistance in demanding applications, including salt storage and marine environments.
Whether you’re in agriculture, industry, or the public sector, MegaDome® Fabric Buildings offer long-term durability, low maintenance, and superior adaptability, making them an innovative and sustainable choice for a wide range of applications.
Fabric Building FAQ
What is a fabric building?
A fabric building is a clear-span steel frame covered with a high-performance polyethylene membrane. MegaDome structures deliver large interior volume, fast installation, and durable performance for agriculture, industrial storage, and municipal use.
How long do MegaDome fabric buildings last?
The galvanized steel frame is designed for decades of service. The membrane lifespan typically ranges from 15–25+ years depending on climate, UV exposure, and maintenance. Replacement membranes are available when needed.
Are MegaDome fabric buildings code-compliant in Canada and the U.S.?
Yes. MegaDome provides engineered drawings and can design to local wind, snow, and seismic requirements for Canada and the United States. Final compliance depends on site conditions and local permitting.
What sizes and profiles are available?
MegaDome fabric buildings offers multiple clear-span profiles and widths to fit your site, (33 to 160 feet) from mid-size to large-scale industrial footprints. Length is modular in set increments. Ask our team for the optimal span and arch profile for your application.
What foundations do MegaDome fabric buildings require?
Foundations vary by site and model. Common options include concrete piers (sonotubes), grade beams, or precast blocks. MegaDome will recommend a foundation solution based on soil report, loads, and local codes.
How much does a fabric building cost per square foot?
Cost depends on size, loads, doors, accessories, and foundation. For budgeting, request a project-specific quote to compare options and total installed cost.
What is the typical construction timeline?
Lead time and on-site assembly vary by model, season, and permitting. After approvals and production, many projects erect quickly compared to conventional buildings. Ask us for current timelines for your region.
Can a MegaDome be relocated or expanded?
Yes. The modular design allows for future length additions and, depending on the foundation and model, relocation to a new site.
What maintenance is required?
Periodic inspections, tension checks, and routine cleaning help maximize membrane life. Address snow removal and drainage per the maintenance guide for your model and region.
