These fenders are called cylindrical and their geometry is the most classic of all.
This type of fender system allows deformations of up to 50% with low reaction at the beginning of the deformation.
The assembly of these fenders is more basic and simple than other types since they are usually fixed to the dock by only two chain anchors (when fender systems with frame require several anchors and usually also chains). Maintenance is also less difficult and cheaper not only because disassembly and installation are easier but also because there are fewer steel components that can develop faults or rust
These fenders are highly robust in performance. The wide range of sizes in which they can be manufactured (both in diameters and length) makes them suitable for a very wide range of applications and for different ranges of ships.
