A D-type rubber fender is a cylindrical fender that has a cross-sectional shape resembling the letter "D." The profile consists of a rounded face and a flat back, making it suitable for installation on the sides of docks, piers, or other marine structures. The fender is typically made of durable, high-quality rubber or elastomeric materials, which provide excellent energy absorption properties when subjected to impact.
The "D" shape is designed to distribute the force of impact evenly across its surface, offering superior cushioning and reducing the chances of damage to both the vessel and the docking infrastructure. D-type rubber fenders are available in a variety of sizes and configurations, making them adaptable to different types of ships, docking systems, and environmental conditions.
D-type rubber fenders are engineered with a simple yet effective design that maximizes their ability to absorb impact forces. The key design elements of a D-type rubber fender include:
Energy Absorption: The rubber material used in the fender is chosen for its capacity to absorb and dissipate the kinetic energy generated during the impact of a vessel against the dock. This helps to prevent damage to the ship's hull and the dock structure, which can be costly to repair.
Durability: D-type rubber fenders are manufactured to withstand the harsh marine environment. They are resistant to water, UV rays, ozone, and various chemicals, ensuring long-lasting performance even in demanding conditions.
Shape and Flexibility: The rounded front of the "D" shape allows the fender to compress and expand under pressure, effectively absorbing shock and reducing the likelihood of direct contact between the ship and the dock. The flat back of the fender allows for easy mounting and attachment to docks or piers.

D-type rubber fenders are the most commonly used dock bumpers. The D fender has a flat back, which makes it easy to install on various surfaces. This can be done by means of bolts and/or strips in various manners: horizontally, vertically, or diagonally. Mounting holes are made through the top and bottom of the fender, or through the sides.
