Aluminium alloy 5052 in H32 temper offers excellent corrosion resistance to seawater as well as marine and industrial environments. It also provides very good weldability and good cold-forming characteristics. This is a medium-to-high strength alloy, with strength slightly higher than alloy 5251 and medium-to-high fatigue resistance. This treadplate is supplied in accordance with BS EN 1386.
Alloy 5052-H32 TripleGrip Treadplate offers the following benefits:
