Gangways and Security

Kropf Marine has extensive experience in fabricating and installing ramps and security gates to enhance your marina environment. These engineered structures are available in custom sizes and designs in order to meet your needs and complement the aesthetic appeal of your marina. Ramps and gates are designed to comply with building code regulations and can be tailored to satisfy accessibility standards for marinas.


Kropf Marine manufactures and installs quality aluminum gangways, bridges, and ramps as access to floating dock systems or other structures. These gangways are typically supplied with a wood or aluminum deck surface, and are availaible with or without handrails.

When used as access to a floating dock system, these gangways are designed with nylon rollers which rest on the dock, allowing for limited independent movement between the ramp and the floating dock.

For locations where the gangway needs to be removed seasonally for winterizing, the deck can be constructed with removable panels to facilitate winterizing without heavy lifting equipment.

Kropf is C.W.B certified for aluminum welding to ensure proper procedures are used in the fabrication of these bridge and gangway structures.

Security Gates

Security is important, both to the marina operator and to the boaters themselves. In many situations limiting access to the docks is essential to providing a secure marina environment where boaters can relax knowing that their valuable investments are protected.  

Our aluminum security gates can help provide that secure environment. Gates can be mounted on the main dock itself, on the access ramp, or on shore. Custom designs and patterns are available, and can be based on your marina’s existing logo. Patterns are plasma cut on a CNC table, allowing for a wide variety of intricate and unique designs that are aesthetically appealing while still providing security.

We can customize each gate to accept a variety of locksets – send us your preferred system and we will design the gate to accommodate it.
