Introduction

The 5052 PE-coated aluminum coil (1.2 mm thickness, 600–2000 mm custom width, 60 μm marine-grade polyester coating) is the UK & European standard for rugged, beautiful, zero-maintenance electrical box and control panel enclosures.

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

• PE powder coating (Qualicoat Class 1): 3000 h salt-spray, any RAL colour, anti-graffiti option.

• Custom width + laser protective film: ready for CNC punching, bending, PEM insertion.
  Result: enclosures that stay factory-new for 25 years in Zone C4/C5 environments, achieve IP66/NEMA 4X, and assemble 70 % faster than painted steel boxes.
