Square Fenders – Reliable Marine Fender Solutions
SME produces square fenders for boats by combining resilient rubber with low-friction UHMW-PE. This innovative design provides excellent wear resistance and high energy absorption, making it ideal for protecting vessels during berthing operations. These marine fenders offer long-term durability, ensuring safe and effective impact protection.
The materials are bonded using a special vulcanizing process, creating a bond that is stronger and more reliable than conventional mechanical joints. This process guarantees long-term performance even under repeated impacts, making SME’s fender systems a top choice for reliable boat fender protection.
These rubber fenders deliver a simple and effective solution for berths with low shear forces. The resilient rubber body provides flexible impact absorption, while the UHMW-PE face reduces friction and minimizes wear during berthing. Customers can select from a variety of standard sizes to match different marine fender applications and berth requirements, making these fenders versatile and easy to install.

FAQs on Marine Fenders
Q1: What is a fender for boats?
A fender for boats is a cushion attached to a vessel’s side. It absorbs impact when docking, preventing damage to the boat. Common materials include rubber, foam, and inflatable rubber.
Q2: What is a fender for docks?
A dock fender is an energy-absorbing system that protects both the dock and the vessel during berthing. It absorbs heavy impacts to prevent structural damage. Examples include cylindrical, cone, and square fenders.
Q3: How are boat fenders different from dock fenders?
Installation: Boat fenders mount on vessels; dock fenders attach to quays.
Energy Capacity: Boat fenders handle light impacts, while dock fenders absorb more significant forces.
Structure: Boat fenders are portable; dock fenders are fixed and built for long-term use.
Q4: Can I use a boat fender on a dock?
No, it’s not recommended. Boat fenders are designed for smaller impacts and mobility, while dock fenders are fixed and built for heavy berthing forces. Using them interchangeably can cause damage.
Q5: How do I choose the right fender system?
For small vessels or yachts: Choose flexible boat fenders (like inflatable or foam).
For ports and larger docks: Use dock fenders designed to meet PIANC or ISO standards.
