Galvanized Sprocketed Rollers

Omni Metalcraft Corp.'s Galvanized Sprocketed rollers combine the rugged construction and quality you've come to expect from Omni sprocketed rollers along with the corrosion resistance of galvanized tubing. The sprockets, axle, and bearings are all mild steel but the main conveying surface is all galvanized. It is the perfect solution for conveyors that are carrying wet or moist product but do not require the full corrosion resistance and washdown capabilities of stainless steel.

Galvanized steel has gone through a chemical process to keep it from corroding. The steel is coated in layers of zinc because it prevents corrosion by forming a physical barrier.
Galvanized steel is widely used in applications where rust resistance is needed. Please view the Roller Index for options.
