Product Introduction
JINYO is a manufacturer integrating R&D, production, sales and service. Its business covers the fields of hydraulic transmission, precision steel pipes and engineering machinery accessories. The company uses advanced honing and grinding machine technology, has unique production and processing capabilities for customized chrome plated rod, hard chrome bar, hydraulic piston rod and hydraulic cylinder tube,honed tubes, SRB tube, and is committed to providing the highest standards of quality and the best service worldwide.


Customized services
JINYO has professional production technicians and advanced production equipment, and can customize the production of chrome-plated rods and honed tubes according to the application requirements of different industries. Whether it is a specific diameter, length or surface finish, we are able to provide chrome-plated rods to meet the needs of your hydraulic system.
In addition to the customization of chrome-plated rods, chrome-plated rods also have excellent durability. The hard chrome-plated surface ensures minimal friction and wear, allowing the hydraulic cylinder to operate smoothly and efficiently. This not only improves the overall performance of the system, but also reduces maintenance requirements, thereby saving costs and increasing productivity. Chrome-plated rods are widely used for hydraulic systems.

Product Features
Hard chrome plated steel rods and tube are designed for use in heavy-duty applications, where strength and longevity are critical. The base material, typically a high-quality steel, is selected for its strength, toughness, and ability to withstand high stress.
The smooth appearance of the hard chrome surface is conferred by an att enti ve preparati on of the chrome steel bars before plating. The steel rod undergoes a rigorous polishing process to create a smooth surface, which is then coated with a layer of chromium through electroplating.
This chrome plating significantly increases the hard chrome plated steel rod’s hardness, making it more resistant to wear and tear, and provides an excellent barrier against corrosion and rust. These hard chrome plated steel rods are widely used in various industrial applications, including hydraulic cylinders, pneumatic cylinders, and other mechanical devices requiring precision and durability.
The hard chrome surface of the Hard chrome plated steel bars confers corrosion and wear resistance, reduces fricti on, improves durability and through abrasion tolerance ensures good oil holding as well.
