Mantel Industries has over 35 years of experiance as a custom aluminum gangway manufacturer. We can tailer your gangway to your individual design needs. Whether designed for use in residential or commercial settings our staff will work with you to engineer a product that meets the loading and environmental requirements for your individual project.
Mantle Industries’ all aluminum structures are designed and engineered to current U.B.C. criteria for their use. Marine ramps mount using our exclusive swing-shackle connection which is simple, strong and allows the ramp to pivot up and down and side to side with the motion of the ocean ( 3 axis of movement ).
Our aluminum marine ramps roll on solid UHMW grooved rollers on UHMW guide tracks and use solid stainless steel axles so there is no maintenance. Full width, hinged transitions plates have been Arc-sprayed with Non-Skid coating and have a tapered UHMW drag edge. These ramps have full length side bars spaced to stop a 4″ sphere and full length handrails on both sides. Decking options include all aluminum decking, fiberglass grating and others. For rainy or snowy locations we offer either an awning cover (in a variety of colors) or a metal roof.
Commercial aluminum ramp widths are usually 4′ to 6′ and lengths vary from 60′ to 120′. Other design options include; anodized handrails, painted finishes, Lexan wind screens, golf cart or 4-wheeler traffic and oversize utilities capacity.

Residential and Private use Aluminum Gangway Ramps and Piers are engineered and designed per current U.B.C. criteria for their use. Consider using an all aluminum bridge as a fixed pier. By spanning 40, 50 or 60 feet you can save on pilings and supports.
Because they’re all aluminum there is no maintenance!
We’ve built clear span all aluminum gangways for Private/Residential use up to a 120′ span but the most common sizes are 40′ to 60′.
Fixed piers are typically 1′ to 2′ wider than the gangway and because they are usually level, can use a less aggressive decking than a gangway ramp. Residential use gangway ramps are quoted including our exclusive swing shackle shore bracket which has a variety of tabs and thru-holes enabling it to bolt to almost any type of shore structure. Gangway ramps also include solid machine grooved UHMW rollers and guide tracks and solid stainless steel axles. The clear span aluminum trusses typically use a round pipe top handrail that’s comfortable to use and very strong.
All trusses have one intermediate safety rail 1/2 way between the deck and the handrail, full-length on both sides. As an option we can quote on providing side spacing to suit your requirements or to satisfy project specifications.
