What is Chrome Plated Hollow Bar & chrome plated od tubing?

Chrome plated hollow bar is known as chrome plated OD tubing also, it plays a very crucial role for producing hydraulic cylinder rods and Linear shafts in various machineries. The primary benefit of using a chrome plated hollow bar over a standard хромированный стержень is that it significantly reduces the weight of the hydraulic piston rod in the design of safety hydraulic cylinders.

The production of chrome plated hollow bars involves taking hot rolled or cold drawn seamless tubes, grinding the outer diameter, polishing it, and then electroplating it with a specific thickness of chrome.
