Our roofing systems are ideal for a wide variety of applications, including chemical processing, water and wastewater treatment, and oil and gas production. TYPES OF TANK ROOFS AND COVERS Tank Cone Roof Tank Cone Roofs are sloped, conical roofs that provide structural stability to tanks while also preventing water from collecting on top of the roof. This type of roof is often made of steel and is commonly used for tanks storing liquids like petroleum, chemicals, and water. Geodesic Dome Tank Roof Geodesic Dome Tank Roofs, also known as aluminum geodesic domes or aluminum geodomes, are spherical, self-supporting structures made of aluminum struts that intersect to form triangles. They offer excellent protection against harsh environmental elements such as wind, snow, and rain, making them ideal for tanks containing hazardous chemicals or other sensitive materials. Trough Deck Roof Trough Deck Roofs are flat, horizontal roofs with a slight slope that allows for water runoff. These roofs are typically made of aluminum and feature a series of troughs and ridges that create extra strength and rigidity. Like Cone Roofs, they are commonly used for tanks storing liquids but are preferred for tanks that require frequent cleaning or inspection. As a internal floating roof manufacturer, we provide external floating roof storage tank, storage tank roof design, floating roof type storage tank, storage tank roof, floating roof oil storage tank, etc. For more, Contact us. There are many bolted tank manufacturers, but we are one of the best choices for you.
