5052 H32 Flat Sheet Marine Grade

5052 H32 is the industry-standard marine grade aluminium alloy, offering superior resistance to saltwater corrosion. It is the preferred choice for boat building, marine fabrication, fuel tanks, and any coastal or high-moisture environment in New Zealand.

Our 5052 H32 flat sheets are available in 1.6mm, 2mm, and 3mm thicknesses across standard sheet sizes (1200×2400, 1500×3000, 1200×3600, 1500×3600mm). All sheets are mill-finish and ready for fabrication or further treatment.
