The SZ-D Fender (Donut Fender) is a ring-shaped, foam filled fender system specifically engineered for installation on fixed piles or poles. Designed to rise and fall with changing water levels, it provides consistent and reliable protection for vessels during berthing operations, regardless of tidal variations.

At the core of the SZ-D Fender is a central steel monopole, which ensures structural strength and long-term stability. The fender is guided by a low-friction UHMW-PE pad, allowing smooth vertical movement along the pile while minimizing wear and maintenance requirements.

A key advantage of the SZ-D Fender is its free-rotating design. This feature significantly reduces friction between the fender and the vessel’s hull, enabling the vessel to slide smoothly along the donut fender rather than rubbing against it. As a result, both the fender system and the vessel experience reduced surface damage, enhanced safety, and improved operational efficiency.

With its robust construction, low-maintenance characteristics, and superior performance in tidal and fluctuating water conditions, the SZ-D Fender (Donut Fender) is an ideal solution for ports, terminals, dolphins, and berthing structures where reliable vessel protection is essential.
