**Company Overview**
Suzhou Weipeng Precision Machinery Co., Ltd. is located in Suzhou, a city known for its foreign trade and economic development, just next to the international port of Shanghai. Established in 2009, we are a manufacturing company specializing in the production of piston rods and linear shafts.
Quality is the lifeblood of our business. Your satisfaction is our top priority. We offer manufacturers of hydraulic and pneumatic cylinders a wide range of high-quality tube and piston products, including:
- Hard Chrome Plated Rod
- Hydraulic Piston Rod
- Cylinder Piston Rod
- Chromium Rods
- Hard Chrome Shaft
- Induction Rod
- Induction Shaft
Our materials include JIS S45C, SAE1045, and DIN CK45. The hard chromium piston rods we produce go beyond standard JIS S45C material, undergoing precision milling and surface chromium treatment to achieve a surface precision level of f7 and a hardness of at least HV800. This enhances wear resistance and extends the service life of the rods, helping customers reduce costs.
We conduct corrosion resistance testing in our internal salt spray laboratory. The surface heat treatment reaches HRC55°±2° with a hardened depth between 0.5mm and 3mm. After precision milling and hard chrome plating, the coating thickness measures 20 microns ±10%, significantly improving wear resistance and extending the rod's lifespan.
These products are ideal for heavy machinery, construction equipment, and various heavy-duty applications. Our chromed steel bars and tubes are used in hydraulic and pneumatic cylinders found in agricultural machinery, lifting equipment, material handling systems, waste collection, and more.

**Chrome Plated Steel Bars**
Our chrome-plated bars are made from medium carbon cold-finished or hot-rolled steel, typically in grade 1045. They are centerless ground, polished, and plated with chrome to a minimum thickness of 0.0005" per side. These bars are designed for use in most piston rod applications in hydraulic and pneumatic cylinders.
**Induction Hardened Chrome Plated Bars**
Our induction-hardened chrome-plated bars are produced using advanced techniques on JIS S45C, SAE1045, or DIN CK45 steel rods. After surface removal, polishing, and induction hardening, they are coated with hard chrome to a minimum thickness of 0.0005" or 0.001" per side. The result is an impact-resistant bar suitable for high-quality piston rods that can withstand harsh environments.
**Applications**
- Hydraulic cylinder rods
- Farm equipment machinery
- Pin stock for equipment attachments
