Frame Materials and Finishes

Iso-Flo® Vibratory Conveyors  and Imspulse® Electromagnetic Conveyors are available with frames of Type 304 and 316 stainless steel, painted mild steel, or thermal-plastic coated mild steel. Meticulously finished, they are easy to clean and keep clean. Stainless steel frames have a handsome blasted finish. Mild steel frames can be painted with Superlife-316® (a liquid stainless steel coating) or durable epoxy paint. Or consider Key’s exclusive thermoplastic coating, designed to withstand today’s strong cleaning chemicals. As attractive as a painted finish, our thermoplastic coating is the most durable, easiest to repair, and most chemical- and corrosion-resistant finish available.
