Why Choose a Pre-Engineered Building System?
Pre-engineered buildings are selected by decision-makers who prioritize efficiency, performance, and lifecycle value. Compared to traditional construction methods, PEB systems offer several measurable advantages.
Accelerated Design & Construction Timelines
Predictable Costs & Material Efficiency
Structural Strength & Weather Resistance
Scalability & Future Expansion Options
Why Choose MegaDome for Your Pre-Engineered Building?
The Engineering Behind Our Pre-Engineered Buildings
At MegaDome, engineering is the foundation of every pre-engineered building we deliver. Our approach prioritizes structural integrity, long-term performance, and adaptability to real-world operating conditions.
Foundation & Site Adaptability
Every PEB project begins with an evaluation of site conditions, including soil composition, frost depth, drainage, and environmental exposure. Foundations are designed to properly transfer loads while accommodating local climate factors and operational requirements. This ensures long-term stability and compliance with applicable building codes.
Structural Framing System
The primary framing system forms the backbone of a pre-engineered building. Columns and rafters are engineered for optimal strength-to-weight ratios, allowing for long clear spans and unobstructed interior space. Secondary framing components support roof and wall systems while contributing to overall structural rigidity.
Load calculations account for:
Snow accumulation and drifting
Wind uplift and lateral forces
Seismic activity where applicable
Equipment and operational loads
Roofing, Cladding & Insulation Options
Roof and wall systems play a critical role in building performance. Harnois offers a range of cladding and insulation options designed to improve thermal efficiency, reduce condensation, and enhance durability. Proper insulation selection helps control internal temperatures, lower energy costs, and protect stored equipment or goods.
Why Choose MegaDome for Your Pre-Engineered Building?
Sealed engineering drawing
Each fabric building models are delivered with a sealed plan, compliant with local building codes and ready for permitting.
Insurable
Because our buildings come with a sealed engineering plan, they’re easier to insure and integrate into your protective cover.
Double Trusses (16″ to 58″)
All our MegaDome fabric building models are designed with double trusses, ensuring superior strength, better load distribution and optimum performance in the most demanding climatic conditions.
Oval tube
Our exclusive oval tube offers increased load resistance while reducing premature membrane wear, thanks to the absence of right-angle edges.
Structural Framing System
The lower section of the arches is always hot-dip galvanized after welding. This part of the arch, which is the critical link between the structure and the foundation, is more exposed to dust and corrosive elements.
Membrane 12 oz HDPE
Superior-quality membrane, guaranteed for up to 20 years, depending on use and conditions. We also offer an exclusive agricultural membrane with 30% light transmission, compared with 16% for standard options.
Foundation & Site Adaptability
A range of fabric building models to suit all your needs, from compact warehousing to large-scale industrial operations.
Corrosion protection
We use the highest-performance galvanizing grades available on the market, guaranteeing optimum protection against corrosion. Each solution is tailored to the specific needs of the application or industry.
Roofing, Cladding & Insulation Options
A range of fabric building models to suit all your needs, from compact warehousing to large-scale industrial operations.
Pre-Engineered Buildings for Commercial & Industrial Use
Pre-engineered buildings are well suited to industries that demand reliability, flexibility, and cost control. Their clear-span designs and customizable layouts support a wide range of operational needs.
- Machinery storage
- Bulk material storage
- Abrasive material storage (sand and salt)
- Heavy equipment storage
- Outdoor storage
- Maintenance workshop
- Compost Facility
- Waste Mangement Facilty
- Mining
- Inventory storage
- Storage for ports and marinas
Each project can be tailored to specific clearance heights, access requirements, and internal workflows, ensuring the building supports operational efficiency from day one.
Pre-Engineered vs Conventional Building Methods
When evaluating construction options, it is important to understand how pre-engineered buildings compare to traditional methods.
PEB vs Conventional Steel Construction
Pre-engineered systems reduce engineering redundancy and material waste by integrating design and fabrication into a single process. Conventional steel construction often requires more on-site labor, longer schedules, and higher variability in cost.
PEB vs Fabric or Tension Structures
While fabric structures may offer lower initial costs, PEBs deliver superior longevity, structural resistance, and insulation performance. For permanent or mission-critical applications, pre-engineered provides greater long-term value.
Lifecycle Cost Considerations
Lower maintenance requirements, energy efficiency options, and long service life make PEBs a cost-effective solution over the full lifespan of the building.
