Aluminum as a building material
Aluminum is an ideal material for the marine environment, it is corrosion-resistant, lightweight, and aesthetically pleasing. There are thousands of designs and concepts out there and you have likely seen many gangways over the years.
This is a great entry-level ramp for commercial applications or recreational customers looking for additional width from the 3-foot ramp. The free-floating shackle system allows the ramp to move in all directions preventing damage to the structure in rough weather. Delrin anti-wear busing protects the aluminum from damage. The bushings can be replaced and dramatically increase the longevity of the ramp. Roller wheels are installed at the end of the ramp to allow the ramp to move with tidal docks.
Handrails can be added to one or both sides of this ramp. Ideal if the height over land or water is significant. Or there is a danger of people or equipment giving into the water.
