Rubber DD fenders

Rubber DD fenders are D-profile rubber buffers designed to protect structures and vessels from impact. The profile typically features a flat rear face for mounting and a rounded outer face to absorb contact forces. In some cases, this D profile may include a hollow section, often referred to as a d hollow fender, which allows additional deformation under load.

They are manufactured from resilient rubber compounds and are used where continuous or point protection is required. Common descriptors include DD bumper, D rubber and d hollow fender; these terms refer to variations of the same D-shaped protective element used across marine and land-based applications.

DD bumper fenders are used to reduce impact and abrasion between moving objects and fixed structures. Typical applications include vessel berthing protection on quays, jetties and marinas, as well as protective edging for piers and pilings.

They are also applied in non-marine settings such as vehicle bays, car parks and industrial loading areas where a robust, compressible barrier is required. The design aims to minimise loads transmitted to the protected structure while providing a durable contact surface.

D rubber protection functions by deforming under load to absorb and dissipate kinetic energy from impacts. The rounded face and resilient rubber compound compress and rebound, reducing peak forces transferred to hulls or structures.

Where a hollow section is present, as in a d hollow fender, the internal cavity allows additional compression, which can further reduce reaction forces during contact. Performance depends on compound properties and installation; regular inspection and cleaning help maintain protective function.

Selection should consider the application type (marine or land), expected contact loads, mounting method, environmental exposure and maintenance requirements. Assess factors such as the size and manoeuvrability of contacting vessels or vehicles, the intended mounting surface, and any regulatory or project-specific constraints.

Material compatibility with saltwater, UV and chemicals may also influence choice. For a precise recommendation based on site conditions and performance needs, consult our technical team for tailored advice.
