It will need to enable the installed equipment to be cleaned to the required standards by being hosed down with high-pressure, high-temperature water jets. It will also, of course, provide its primary function of protecting the housed electronic or electrical system from contamination.
Material
Stainless steel is the default material for use in environments where corrosion resistance is a prerequisite. For internal use, 304-grade material is more than adequate.
