All Ronautica Marinas structures, including gangways, walkways, gates, pontoons, and fingers, are manufactured in high quality marine grade aluminium 6005 A-T6. The aluminium profiles used in construction make them very strong, yet because aluminium is lightweight and flexible, it is ideal for dynamic marine environments. Because aluminium does not rot or rust, it needs no maintenance over its life even in salt water environments. Although galvanised steel should not rust, if scratched, chipped, or modified during installation or when in use, in marine environments it often does rust and requires maintenance.
Ronautica Marinas offer access bridges and access gangways of almost any length and width. Typically bridges and gangways are between 16 and 24m length, and 1.5m wide, with 2.5kN/m2 loading, but Ronautica Marinas engineers can design and manufacture them shorter, longer, narrower, wider, and with a higher loading. The connection to the quay and the pontoon can also be customised to suit any installation. Ronautica Marinas can also design and manufacture security access gates to fit on the quay, or on the gangway.
Ronautica Marinas also supply pontoons and fingers. Pontoons are typically between 2m and 3m wide, and can be any length (by connecting them together). Fingers are typically less than 1.5m wide, and between 6m and 12m length. Again, other dimensions can be provided. The profile and weight of aluminium used in the pontoon and finger construction is dependent upon the environmental conditions to which they will be exposed. Pontoons and fingers sit on floats of either concrete, or polyethylene encased polystyrene. The height of the float dictates the pontoon freeboard (height above the water), with 500mm being the norm. On bridges, gangways, pontoons and fingers, Ronautica Marinas can offer hardwood decking, wood composite decking, or GRP mesh decking.
