Stainless steel Rigid Conduit
- RMC’s stainless steel rigid conduit is manufactured in alloy grade 304 and 316.
- RMC’s Stainless steel rigid conduit features a hygienic polished finish, delivering an exceptional aesthetic appearance and a consistent surface. This finish enhances cleanability and significantly reduces the risk of microbial bacteria accumulation.
- Among metallic electrical raceway options, stainless steel offers the highest corrosion resistance, along with exceptional strength and temperature performance.
- RMC offers stainless rigid conduit in grades 304 and 316, with 316 providing better corrosion resistance in chloride, sulfide and marine environments due to its slightly higher nickel content and the addition of molybdenum.
- Both 304 and 316 stainless steel offer excellent strength and temperature performance, with 316 providing slightly higher heat tolerance, up to 1550°F.
- Each length of RMC stainless steel conduit is provided with one threaded UL coupling.

Applications
- RMC offers stainless rigid conduit in grades 304 and 316.
- Both 304 and 316 stainless steel offer excellent strength and temperature performance with 316 providing slightly higher heat tolerance up to 1550°F and better corrosion resistance in chloride, sulfide and marine environments due to its slightly higher nickel content and addition of molybdenum.
- RMC 316 stainless steel features a hygienic polished finish that delivers outstanding protection in challenging environments, including marine areas, chemical processing facilities, and food processing plants where rigorous chemical washdowns are essential.
- RMC’s stainless rigid conduit significantly reduces the need for maintenance and replacement of conduit and fittings in corrosive environments and demanding applications.
