Aluminum Alloy 5052 Aluminum Coil Electrical Box Enclosure Panel (1.2 mm | Custom Width | Gray PE Coating)

Introduction

The 5052 gray PE-coated aluminum coil (1.2 mm thickness, 600–2000 mm custom width, 60–80 μm Qualicoat Class 1 polyester powder in standard RAL 7035 light-grey) is the UK & EU industry favourite for rugged, elegant, zero-maintenance outdoor & industrial electrical enclosures.

• Alloy 5052-H32: 35 % stronger than 3003, excellent corrosion resistance & formability.

• RAL 7035 light-grey PE coating: 3000 h salt-spray, perfect match for Schneider, Siemens, and ABB standard colours.

• Custom slitting + protective film: ready for CNC punching, folding and rivet-nut insertion.
  Result: cabinets that stay factory-fresh for 25 years in British coastal rain, achieve IP66/NEMA 4X, and are built 70 % faster than painted steel.
