CR3 Zinc-Plated Drum Closures

CR3 trivalent chromium passivation is available for buyers whose specifications require this zinc-plated finish. It provides corrosion protection and is widely used for standard industrial drum applications.

CR6 Zinc-Plated Drum Closures

CR6 hexavalent chromium passivation provides strong corrosion resistance for demanding industrial applications. Buyers should confirm local regulatory and end-market requirements before selecting CR6.

Lacquer-Coated Drum Closures

Lacquer-coated closures are available in multiple coating systems for different contents and chemical environments. Product compatibility should be verified before ordering because lacquer performance depends on the filled material and operating conditions.

Important Compliance Note

Drum closures are components of a complete packaging system. A closure does not independently carry the UN certification of a finished drum. UN marking applies to the tested and approved complete packaging configuration. Qiming Packaging also exports complete 200L plastic drums with applicable UN marking and 200L metal drums; buyers should verify the complete drum specification and intended filling application before shipment.
