Gas Cylinder Cages are designed for secure on-site storage of up to twenty compressed-gas-cylinders. The cage is all-steel tube and plate construction including ¾ inch number 9 expanded metal screen sides for natural ventilation and visual inventory and inspection. Cylinders are held in place by adjustable chains and the hinged access-door can be locked with a padlock to deter theft and unauthorised access. The complete unit can be moved about the construction site via a crane hoist connected to the top-mounted lifting eye. There are also four hollow-structural tubes welded to the base for maneuvering by fork-lift.
