Tank Covers

Protecting Your Tank with Superior Roof Solutions

A roof is a critical component of any tank system, serving as the first line of defense against environmental threats and ensuring the long-term integrity of your investment. Without a proper roof, tanks are vulnerable to contamination, evaporation, and damage from the elements, all of which can compromise the quality of the stored contents and reduce the lifespan of the tank. By choosing the right roof, you not only protect the tank itself but also enhance its overall performance, safety, and longevity.

Five Key Reasons Why a Roof is Essential





Enhanced Structural Integrity

A well-designed roof adds an extra layer of support to the tank, helping to distribute weight evenly and prevent the tank shell from deforming under pressure. This structural integrity is crucial for maintaining the tank's shape and functionality over time.





Increased Sturdiness and Stability

The addition of a roof significantly improves the overall sturdiness of the tank, making it more resistant to external forces such as wind, rain, and snow. This added stability ensures that the tank remains securely in place, even in challenging environmental conditions.





Protection Against Contamination

A roof prevents debris, dust, and other contaminants from entering the tank, which is essential for maintaining the purity of the stored contents. This protection is particularly important for tanks used in sensitive applications like water storage.





Reduced Evaporation

By covering the tank, a roof helps to minimize the loss of liquid through evaporation. This is particularly important for water storage tanks, where evaporation can lead to significant water loss over time.





Longevity of the Tank Shell

A roof shields the tank shell from direct exposure to the elements, such as UV rays, rain, and temperature fluctuations, which can cause wear and tear. This protection extends the lifespan of the tank shell, ensuring that it remains in good condition for many years.

Tank Cover Options

Dome Roof

Ideal for Smaller Tanks with Liners

The Dome Roof is specifically designed for tanks up to 23.69m in diameter and is the perfect solution for tanks that use liners. This design features a column-free structure, allowing for maximum storage capacity and ease of maintenance. The trusses, constructed from 40mm to 80mm square tubing, are available in galvanized or epoxy-coated finishes, ensuring durability and resistance to corrosion.


The Dome Roof’s arched design not only enhances structural strength but also contributes to better water runoff, preventing water accumulation on the roof that could lead to potential damage. This roof type is particularly beneficial in environments where space and accessibility are critical.

Flat Roof

Built for Large Diameter Tanks without Liners

For larger tanks that do not require liners, the Flat Roof offers a robust and reliable covering solution. This design features a main arch constructed from channels, supported by lip channels on the sides, ensuring the roof can withstand the demands of large-scale storage. The Flat Roof’s straightforward design makes it ideal for tanks where easy access and structural stability are priorities.


The Flat Roof is built to provide maximum protection while maintaining a simple yet effective design. The flat surface allows for easy installation of additional equipment or modifications, making it a versatile choice for various applications

Choosing the Right Roof for Your Tank

The decision between a Dome Roof and a Flat Roof depends on the specific needs of your tank. The Dome Roof is best suited for smaller tanks that utilize liners, offering a strong, arched design that maximizes internal space and provides superior water runoff. On the other hand, the Flat Roof is ideal for larger tanks without liners, providing a simple, sturdy cover that can support additional equipment and withstand harsh conditions.

Both roofs offer exceptional protection, durability, and longevity, ensuring that your tank remains secure and efficient for years to come.

Don’t leave your tank exposed to the elements—order a roof with your tank to enhance its integrity, sturdiness, and stability. Whether you’re purchasing a new tank or looking to upgrade an existing one, our Dome and Flat Roofs can be added to any tank design. Protect your investment and ensure the long-term performance of your tank system by choosing the right roof today.
