Products & Services
Protocase manufactures fully finished custom electronic enclosures and associated parts from a wide variety of materials and components, in 2-3 days with no minimum order. Protocase also provides expert and affordable enclosure design services.
Cold Rolled Steel
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
