Protocase recommends cold rolled steel for general purpose enclosures. It offers a good combination of cost and structural integrity (stiffness).

If corrosion resistance is required, consider galvanneal, stainless, or aluminum. Likewise consider aluminum where minimum weight and/or corrosion resistance is a consideration.

Finish:
Powdercoat or Unfinished

Fasteners:
Typically use zinc plated steel PEMS and fasteners

Welding:
Highly weldable with seam or spot processes
