Aluminum Alloy 5754 Plate for Offshore Platform Protective Panels (3.0 mm | Custom Width | Anodized Corrosion-Resistant Layer)
Introduction
The 5754 anodized aluminum plate (3.0 mm thickness, 1000–2600 mm custom width, 25 μm hard-anodized + sealed layer) is the global offshore industry’s ultimate solution for zero-maintenance, ultra-durable protective panels.
-
Alloy 5754-H111: 3.5 % Mg → 40 % stronger than 5086, DNV-GL & ABS certified.
-
Class-I hard anodizing: 2000 h ASTM B117 salt-spray, permanent metallic finish.
-
Extra-wide coil + laser-flatness: ready for wind-wall, helideck edge or blast panels.
Result: panels that survive 50 years in Zone C5-M marine atmosphere, reduce platform weight 3.2 t per 100 m², and install 80 % faster than stainless steel.
