What material should the straps for steel tanks be made of?

The appropriate material for the straps used to secure steel tanks is typically flat steel. Steel tanks require strong, durable straps that can withstand the considerable weight of the tank as well as any stresses that might occur during installation or operation. Flat steel provides the necessary structural integrity and is also resistant to the corrosive elements often found in fuel or chemicals stored in these tanks.

Using a nonmetallic material would not provide the strength needed for sufficient support, while plastic may not be reliable due to potential environmental factors such as temperature changes that could lead to brittleness. Rubber, while it is flexible and can help with vibration damping, does not offer the rigidity and support required for holding a steel tank securely in place. This makes flat steel the most suitable choice for ensuring the safe installation and functioning of underground storage tanks.
