Suitable for harsh, corrosive environments, the chrome-plated bar is designed to meet salt spray testing. The manufacturing process begins with special cold finish preconditioning of the raw steel and tubing, then the company controls size, surface finish, roundness and straightness to meet buyer’s requirement.

Besides, we also provide the machining work for your rod, we can have the rod machined as per your drawing and request, like having the rod drilled , threaded, etc. Making it is ready for assembling with cylinder tube, you can save work and time.
