Materials, Components & Finishes

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.

Powdercoat or Unfinished

Typically use zinc plated steel PEMS and fasteners

Highly weldable with seam or spot processes

The gauges shown above are based on American CRS sheet steel manufacturers gauge thickness. These will vary from british gauges with some exceptions.

Hot Rolled Steel

Hot rolled steel features a scaly black finish, and more rounded/less precise corners than cold rolled steel. For these reasons, hot rolled steel is more ideal for applications wherein aesthetics and extremely precise dimensions are not required.

Hot rolled steel bars offer excellent general-purpose structural quality, and are easily welded and machined.
