What materials are low pressure cylinders typically constructed from?

Low pressure cylinders are typically constructed from aluminum and steel due to their strength-to-weight ratios and durability. Aluminum offers a lightweight alternative that is resistant to corrosion, making it an ideal choice for portable cylinders. Steel, known for its robustness, provides excellent pressure containment, which is crucial in applications involving gases and fluids. The combination of these materials enables the cylinders to withstand the pressures and environments they are subjected to while also remaining manageable for handling and transport.

While other materials may also be used in the construction of cylinders for specific applications, aluminum and steel remain the prevalent choices for low pressure cylinders because of their proven effectiveness in a variety of settings, including firefighting operations.
