Below is a list of Used Drums manufacturers from Ontario. Used drums are drums that have been previously used for storage and transport applications. The two main types of used drums are reconditioned drums and remanufactured drums. Reconditioned drums can be either plastic or steel drums that have undergone the reconditioning process to ensure optimum repeat use. Whereas in drum reconditioning, the drum is not often altered with new materials or parts (except for the lid), remanufactured drums must undergo a much more intense process, changing many aspects of the old drum.
