PTC offers a comprehensive range of chrome-plated products and machined components, ensuring high-quality, durable surfaces with options for various applications and superior corrosion resistance.


PTC offers a full line of chrome plated products including Tubing and Bar, at our Tubular and Bar Machined Components facility located in Hannibal, Missouri. 

In house centerless grinding (Acme) along with our three automated plating lines ensure that each step in the manufacturing process is monitored to yield flawless product performance, long life, and durability.

All of PTC’s plated bar products are available as chrome plated only or induction hardened and chrome plated. We also offer selectively hardened bars to match your machining requirements. 

Our durable surfaces meet or exceed all industry standards for corrosion resistance, coefficient of friction and wear loss.

We also offer Caserod, an induction-hardened, precision ground shafting typically for non-plated applications that will be subjected to excessively hard wear or for security bar applications.

Common applications:   

  • Chrome-plated tubing and hollow piston rods for telescopic hydraulic cylinders

Chromerod Extreme

This proprietary chrome-plating system delivers vastly superior corrosion resistance and offers 1000 hour life when tested to the neutral salt-spray specification (ASTM B-117).
