Chrome plated tube: General Introduction
The chrome plated tubing is also commonly referred to as chrome plated hollow bar and is an important material for the production of hydraulic piston rods. The chrome plated outer diameter provides a lightweight option for the design of safe hydraulic cylinders. The popularity of chrome plated OD tubes in the field of hydraulic cylinder manufacturing highlights its importance.
Chrome plated tubes also are known as hollow chrome rods, are manufactured from cold-drawn seamless tubes or hollow bars. The outside diameter of the tube is chrome-plated to a specific thickness after undergoes grinding and precision polishing. So in the USA, these tubes are commonly referred to as chrome-plated OD tubing. The use of chrome-plated tubes in hydraulic piston rods helps to reduce weight and is widely used in the manufacture of hydraulic cylinders.

Chrome plated hollow bar: Applications
Chrome plated hollow rods have a variety of applications, including:
- use in the manufacture of hydraulic piston rods for hydraulic cylinders,
- as well as in applications where high-performance surface finishing and high dimensional accuracy are required.
- These rods can also be used in pneumatic systems, where reducing the weight of the piston rod is desirable, while still maintaining strength and corrosion resistance.
- Other applications of chrome plated hollow rods include use in various industries, such as construction, engineering, and the automotive industry.
In addition to chrome plated od tubing, there is also chrome plated inner diameter tubing (chrome plated ID tube). This is created by chrome plating the inner diameter of honed tubing to a specific thickness.
