Hollow Chrome Plated Bar

Hollow chrome plated bars, also referred to as chrome plated tubes, are manufactured from cold drawn seamless tubes or hollow bars. The process involves grinding and precision polishing of the outer diameter, followed by chrome plating to a specified thickness. These bars are known for their chrome plated exterior on the OD (Outside Diameter), earning them the name chrome plated OD tubing as well.
