Chrome hollow bar we also call it chrome plated tubing,it is a kind of tube which inner surface is honed and the outer surface is chrome plated.
The chrome plated surface provides excellent wear and corrosion resistant performance of the tube. Chrome plated steel tubing has an excellent durability and helps reducing friction. Chrome plated pipe is mostly used as hydraulic piston rods in order to have a lighter hydraulic cylinder. And chrome plated OD tube also can be utilized for applications where precision outside diameter or high smooth outside surface is required. Chrome plated OD tubes can be supplied with honed inside surface for telescoping hydraulic cylinder applications too.
Chrome hollow bar mainly suitable for elevator cylinder, telescope cylinder, scaling ladder, agriculture machines, engineering machinery, construction machinery etc.
