Mild Steel Enclosures

Shop mild steel enclosures at RS Electrical Supplies. Mild steel electrical enclosures provide robust mechanical protection for electrical components, control equipment, distribution boards, and terminal assemblies in industrial, commercial, and heavy-duty applications. Stronger and more impact-resistant than ABS plastic alternatives, mild steel enclosures are the preferred choice where physical security, EMC shielding, or high mechanical strength is required. Typically supplied with a powder-coated finish for corrosion resistance.

Key Properties of Mild Steel Enclosures

  • High mechanical strength — superior impact and crush resistance compared to plastic enclosures
  • EMC shielding — steel construction provides electromagnetic compatibility (EMC) shielding for sensitive electronics
  • Powder-coated finish — RAL 7035 light grey powder coat as standard on most enclosures, providing corrosion resistance for indoor use
  • Earthing provision — steel body allows direct earthing of the enclosure for safety compliance
  • DIN rail and mounting plate compatible — suitable for fitting DIN rail, terminal blocks, and control components internally

Available Sizes & IP Ratings

Mild steel enclosures are available in a range of sizes from small wall-mount boxes to large floor-standing cabinets. IP54 and IP65 rated options available — suitable for indoor industrial environments and protected outdoor locations. For fully corrosion-resistant outdoor or washdown applications, see our Stainless Steel Enclosures range.
