gangways View additional Gangway photos!
Gangways are typically used to connect two usable areas that are separated by an impassable gap. Our marine gangways usually connect a seawall or dock to a floating dock or platform. However we do build many variations which are used in commercial, industrial and residential applications.

Standard gangways are either 36 or 48 inches in usable width. They have a heavy duty piano style hinge at one end and a set of four or six polyolefin non corrosive rollers at the other end. They have two full length handrails 40 inches high that come standard with two mid height barrier bars. The length can be from 3 feet to 34 feet. All material is 6061 –T6 or 6063 aluminum with stainless steel hardware. Our gangways are light weight yet strong, with a load rating at 100 pounds per sq. ft. Our handrails are the truss type and provide a significant amount of support. They bolt on and off with stainless steel bolts so the entire system can be packaged and crated for shipping. This reduces shipping cost greatly (well over half in most cases).

The decking material is an aluminum planking designed specifically for gangway and dock applications. It interlocks with a very high quality non skid surface for both strength and safety. All of our decked surfaces are cross braced underneath to increase loading and provide lateral strength. In the real world gangways are subject to much more than just static vertical loads.

Twisting and lateral movement can lead to structural failure just as quickly as over loading can. This is why all of our gangways are cross braced on the underside.

Options on a gangway can include almost anything to fit your needs. Safety cable tie downs and straps, lifting eyes, carrying handles, custom hinges or dog ears are just a few. We have designed and built gangways and catwalks for clients ranging from the United States Navy and Coast Guard, to the National Parks Service to private companies like the Hilton hotel and the Mercedes Benz company.

Gangway sections are designed for 100 pounds per sq. ft. and a concentrated vertical load of 300 pounds distributed over an area of one sq. ft. Handrails are designed to resist a load of 200 pounds applied at any point at any direction or 50 pounds per liner foot uniform load.
