Dedicated to closures & caps and relevant die & machines for drum makers, and compatible parts and tools adopted by drum users, we are always on the way to offer integrated packaging solution to steel drum market. The most general drum with a non-removable top cover is what we called the "closed head drum" or "tight head drum", respectively the fully removable top cover one named as "open head drum". There are distinguished closing systems for steel drums whereas their top cover types.
Those with standardized sizes of G2 and G3/4 are the essential closures for tight head steel drums, such as steel drum flange, steel drum plug, metal cap seal, plastic bung, nylon plug, drum paint cap. It is found that in different situations, these components are proved to be the initial safety keepers. When they need to be installed or removed, bung wrench, crimping tools are exactly applied to cater to their adequate torque and tightness.
The body and top cover of the open head steel drum are rimmed with a drum locking ring, which is welded with a drum clamp, drum bolt and lugs with nuts and washers. There could be secondary security with a plastic T seal or metal latch across the holes of the clamp.
