Greatario’s aluminum domes and specialty covers are engineered to deliver long-term protection, structural performance, and visual appeal for critical storage and treatment infrastructure. Designed for municipal, industrial, wastewater, and bioenergy applications, these custom aluminum roof systems combine efficient design with proven durability, backed by decades of large-scale project experience across Canada.
Whether covering a potable water tank, wastewater treatment process, biogas digester, or industrial storage structure, Greatario provides custom-engineered aluminum dome covers and specialty roof solutions built to perform in demanding environments.
As part of our integrated tank and cover offering, we provide one of the most comprehensive lines of aluminum roof and cover options available, designed, fabricated, and installed by an experienced Canadian team.
Each aluminum cover system is selected and engineered based on tank size, application, environmental exposure, and operational requirements.
Extruded Flat Aluminum Covers: A cost-effective and durable aluminum tank cover solution suitable for a wide range of municipal and industrial storage applications.
DID YOU KNOW?
Greatario built Canada’s largest aluminum geodesic dome in Cochrane, Ontario—an industry-leading structure measuring 97.5 metres in diameter and 52 metres high.
This project underscores Greatario’s capability to deliver large-scale, complex aluminum dome cover systems with precision and confidence.

Engineered Durability
Designed to withstand harsh Canadian weather conditions, including snow loads, wind exposure, and temperature fluctuations—while minimizing maintenance requirements.
Custom-Engineered Solutions
Every aluminum dome and specialty cover is tailored to the specific tank geometry, site conditions, and operational needs of your project.
Efficient, Lightweight Design
Aluminum construction allows for efficient installation and structural performance without compromising strength or longevity.
Clean, Modern Aesthetic
Sleek aluminum roof systems enhance the appearance of municipal and industrial facilities while supporting functional performance.
Versatile Applications
Suitable for a wide range of uses, including:

Aluminum dome covers are commonly used to protect storage tanks in municipal water, wastewater treatment, industrial storage, and bioenergy applications. They help prevent contamination, reduce emissions, and protect infrastructure from weather exposure.
Aluminum offers excellent corrosion resistance, a high strength-to-weight ratio, and lower long-term maintenance requirements compared to many steel alternatives—making it ideal for harsh or exposed environments.
Yes. Aluminum geodesic domes are specifically designed for large-diameter tanks. Their self-supporting structure efficiently distributes loads and allows for scalable designs, even at very large sizes.
Absolutely. Greatario designs each aluminum dome or cover system to meet project-specific requirements, including tank size, environmental conditions, access needs, and operational constraints.
Yes. Greatario’s aluminum dome covers and specialty roof systems are widely used in wastewater treatment and biogas digester applications, where durability, corrosion resistance, and performance are critical.
