Chrome Plated Rod Manufacturer in ChinaZTU Steel is a professional manufacturer of hard chrome plated rods for hydraulic and pneumatic cylinder applications. With more than 17 years of production experience, we provide high-quality chrome plated rods to customers worldwide.
Our chrome rods are manufactured from premium carbon steel and alloy steel materials, then processed through precision grinding and hard chrome plating to achieve excellent wear resistance, corrosion resistance and dimensional accuracy.
The products are widely used in hydraulic cylinders, pneumatic cylinders, construction machinery, agricultural equipment, mining machinery and industrial automation systems.
A chrome plated rod is a precision ground steel bar coated with a hard chromium layer on its surface.
The chrome plating process significantly improves:
Surface hardness
Wear resistance
Corrosion resistance
Surface smoothness
Service life
Chrome plated rods are commonly used as piston rods in hydraulic and pneumatic cylinders where high precision and durability are required.
ZTU Steel supplies chrome plated rods in a wide range of materials.
