Engineered Permanent Fabric Structures
Providing MegaDome structures to Manitoba and Saskatchewan.
High-strength steel frames, long-span oval tube design, and tensioned membranes engineered for North America.
Manitoba MegaDome provides MegaDome® structures to Manitoba and Saskatchewan. MegaDome® is a Canadian manufacturer of permanent fabric buildings, specializing in turnkey storage and operational structures for demanding environments. Since 1999, we have engineered, manufactured, and installed fabric-covered buildings designed to perform reliably in industrial, agricultural, and municipal applications across North America.
Our structures are a proven alternative to steel or wood buildings, offering faster commissioning, predictable budgets, and engineered performance tailored to your site.
A permanent fabric building is an engineered structure designed for long-term use, combining a structural steel frame with a high-performance tensioned fabric membrane. Unlike temporary shelters, these buildings are engineered to meet local building codes—including snow load, wind load, and site-specific requirements.
Each series is engineered for durability, scalability, and long-term performance.
