FAQ
Q1: How do I pick the right cylindrical fender size?
A1: Provide vessel LOA, beam, displacement and typical berthing speed. We calculate berthing energy and recommend diameter/length and mounting type.
Q2: Can cylindrical fenders be used on floating docks?
A2: Yes — rope/chain lash or bracket-mounted cylindrical fenders are standard for floating pontoons and docks.
Q3: Are replacements and spare parts available from stock?
A3: Standard sizes are typically stocked; custom sizes can be produced with short lead times and shipped globally.
Q4: How do cylindrical fenders compare with other fender types?
A4: Cylindrical fenders offer simplicity, uniform contact and lower cost; for very high-energy berths, cone or cell fenders may be preferable.
Q5: Do you supply a full cylindrical fender catalogue?
A5: Yes — we provide a detailed catalogue with dimensions, performance tables and mounting recommendations to support procurement and installation.
