Depending on the structure, rubber fenders are generally divided into two broad categories: solid rubber fenders (non-floating) and floating rubber fenders.

Solid rubber fender (non-floating) is an anti-collision device for dock ships with a long history of application and a wide range of applications. According to the force of the rubber fender, it can be divided into shear type, rotary type and compression type; according to the structure of the fender, the solid rubber fender can be further divided into D type, cone type, drum type, sector shape, rectangular shape, cylindrical shape. Fenders, etc.

Floating rubber fenders are free to float on the water and can be divided into: inflatable rubber fenders and filled rubber fenders, depending on the internal cushioning medium.

Inflatable rubber fenders use compressed air as a medium to work with compressed air to consume collision energy.

Foam-filled fenders, also known as solid polyurethane fenders, contain buffer media primarily as closed-cell foaming materials such as foamed EVA, expanded polyurethane and foamed rubber.

The solid rubber fender has high energy absorption and reaction force, and has the advantages of low cost, long service life, simple installation and maintenance, etc. It is a protective device installed in the dock and the dock.

The floating rubber fender is a new type of fender equipment. Compared with the solid rubber fender, its main features are: large compression deformation, large energy absorption, small reaction force, self-floating, easy installation. It is usually used in ship to ship, ship to wharf bargaining, docking, etc. Because of its self-floating characteristics, it is also particularly suitable for installation at terminals with large tidal level changes. Among them, the filled rubber fender is especially suitable for applications in harsh environments due to its maintenance-free and long life, such as offshore drilling platforms.
