Aluminum Alloy 5754 Aluminum Plate Recommended for Offshore Platform Protective Panels (3.0 mm | Custom Width | Anodized Anti-Corrosion Layer)

Introduction

The 5754 anodized aluminum plate (3.0 mm thickness, 1000–2600 mm custom width, 25 μm hard-anodized + sealed anti-corrosion layer) is the offshore industry’s most recommended material for long-life, zero-maintenance protective panels in the harshest marine environments.

• Alloy 5754-H111: 3.5 % Mg → 40 % higher strength than 5086, NORSOK M-501 & DNV-GL approved.

• Class-I hard anodizing: 2500 h ASTM B117 salt-spray, permanent metallic finish.

• Extra-wide + laser-level flatness: perfect for wind walls, blast panels, helideck edges and accommodation cladding.
  Result: panels that survive 50+ years in C5-M / CX offshore atmosphere, save 3.2 t per 100 m² vs stainless steel, and install 80 % faster.
