When it comes to tensioned fabric structures, the name “Sprung buildings” often comes up as a benchmark in the industry. Known for their versatility, rapid installation, and durability, these buildings have become a popular solution across sectors like mining, oil and gas, agriculture, and recreation. At MegaDome, we offer a Canadian-made, Canadian-engineered alternative that delivers all the benefits of Sprung buildings—backed by local manufacturing, expert engineering, and unmatched customer support.
What Are Sprung Buildings?
Sprung buildings refer to tensioned membrane structures made from a high-performance fabric stretched over a rigid frame. These buildings are known for their durability, quick deployment, and adaptability to extreme environments.
But it’s important to note that “Sprung” is also a brand—and while they’ve helped define the category, they are not the only option.
MegaDome manufactures fabric buildings that meet and exceed the same performance criteria as Sprung buildings, with additional advantages: every MegaDome structure is made in Canada, engineered in Canada, and tailored to your site and industry.
MegaDome: A Proven Canadian Solution
Located in Saint-Thomas, Quebec, MegaDome fabric buildings are manufactured entirely in Canada, using North American steel and proprietary membrane technology. Unlike many imported or franchised solutions, our buildings are designed specifically for the Canadian and northern U.S. climates—offering superior performance in snow, wind, and temperature extremes.
Our structures are true engineered buildings, meaning they’re stamped by professional engineers and fully compliant with the National Building Code of Canada and applicable U.S. codes. This makes MegaDome a trusted alternative to Sprung buildings, with the added benefit of local support and shorter lead times.
Shared Advantages of Sprung and MegaDome Buildings
Both MegaDome and Sprung buildings share many core benefits:
- Fast Installation: Fabric buildings can be erected in weeks, not months, saving time on site and reducing labor costs.
- Modular Design: Both structures are designed for easy expansion or relocation.
- Durability: High-strength steel frames and weather-resistant fabrics ensure long lifespans, even in the harshest environments.
- Natural Light: Translucent membranes reduce the need for artificial lighting during the day, lowering operational costs.
- Versatility: Suitable for industrial, commercial, municipal, and agricultural use.
So, why choose MegaDome?
What Sets MegaDome Apart1. Made in Canada, For Canadian Conditions
Unlike global suppliers, MegaDome designs and manufactures every structure in Canada. This means your building is built with Canadian snow loads, wind pressures, and climate realities in mind—not retrofitted or adapted after the fact. Local production also means faster delivery, easier communication, and ongoing support.
2. Certified Engineering Every Time
MegaDome doesn’t believe in one-size-fits-all buildings. Each structure is engineered for your specific location, site conditions, and application. You’ll receive stamped drawings, full load calculations, and permit-ready documentation. Whether it’s a salt storage facility in Ontario or a grower greenhouse in British Columbia, we engineer it right the first time.
3. Exclusive Oval Tube Framing
Our patented oval tube steel framing system delivers superior structural strength compared to traditional round-tube frames. The oval design offers better resistance to buckling and stress, allowing for wider arch spacing and less steel—without compromising structural integrity. It’s strong, efficient, and uniquely MegaDome.
4. North American Steel and Membrane
We only use 50 KSI graded steel—52% stronger than commercial-grade steel typically used in imported structures. Our membrane is an industrial-grade polyethylene that offers excellent UV resistance, light transmission, and anti-condensation treatments. Whether you need a white interior for reflectivity or a darker shade for light blocking, we’ve got a solution.
5. Customization and Scalability
From 30’ wide to over 120’, our structures are available in a wide variety of widths and lengths. You can choose from freestanding, open-end, or closed-end configurations with various doors, sidewall heights, ventilation, and lighting options. And as your operation grows, so can your building—thanks to our modular design.
Applications That Go Beyond Expectations
Like Sprung buildings, MegaDome structures are used across dozens of industries:
- Mining and Energy: Temporary workshops, conveyor covers, equipment storage, or even workforce housing.
- Agriculture: Hay, grain, and machinery storage; livestock shelters; greenhouse production.
- Municipal: Salt and sand domes, vehicle storage, waste handling.
- Sports & Events: Riding arenas, gymnasiums, event pavilions, and more.
- Construction: Temporary shelters, heated workspaces, and on-site storage.
In each case, clients trust MegaDome to deliver rugged, reliable structures that perform all year round.
Real-World Reliability
Our buildings are installed across North America—from the harsh winters of Saskatchewan to the humid coasts of Nova Scotia, and everywhere in between. We’ve served municipalities, private companies, co-ops, and global corporations who needed dependable shelter in record time.
Each project is supported by a technical team with decades of experience in tensioned membrane architecture. We don’t just sell buildings—we engineer solutions.
Warranty and After-Sales Support
Unlike offshore options, MegaDome offers Canadian-based customer support, field service, and installation assistance. Our warranty covers both the membrane and the structure, and we keep parts readily available. We also work with a network of certified installers and can coordinate on-site supervision if needed.
We’re with you before, during, and after the build.
Canada’s Best Choice for Sprung-Style Buildings
Sprung buildings have earned their reputation, but they’re not the only name in the game. MegaDome offers the same speed, performance, and longevity—with the added benefits of Canadian engineering, faster delivery, and local support.
When you need a sprung building that’s tailored, compliant, and built to thrive in harsh conditions, choose MegaDome. It’s not just a fabric building—it’s an engineered shelter made in Canada, for Canadians (and beyond).
