Are bolted or riveted faux steel C-Channels suitable for spaces where moisture may be present?
Yes. Industrial Series faux steel C-Channels are made from PVC and are water resistant, so the material does not develop the rust and corrosion associated with actual steel. Installation conditions and the surrounding structure still need to be appropriate for the environment, but the C-Channel itself provides a steel-inspired appearance without relying on corrosion-prone metal.
