Our core portfolio covers all extruded fender needs, directly aligning with target keywords: single-unit Extruded Rubber Fender (for small-scale use), bulk-ready Extruded Fenders (and lowercase extruded fenders, for search matching), industrial-grade Extruded Rubber Fenders (for heavy-duty impact), and precision Extruded Fender Bumper (for edge protection).
Characteristics
Precision Extrusion Technology
The extruded rubber fender products are manufactured using advanced extrusion processes that ensure consistent profile accuracy, uniform material density, and optimal performance characteristics throughout the entire fender length.
Enhanced Impact Absorption
Our extruded fenders feature optimized geometric profiles that provide excellent energy dissipation and low reaction forces during vessel berthing operations, significantly reducing impact on marine structures.
Superior Durability
All extruded rubber fenders are manufactured from premium marine-grade rubber compounds that offer exceptional resistance to abrasion, UV radiation, ozone exposure, and harsh environmental conditions.
Versatile Bumper Applications
The extruded fender bumper systems are designed with flexible mounting options, providing adaptable protection solutions for various marine structures and vessel types.

FAQ
Q1: What types of extruded fenders are available?
A1: We supply D-type, square, cylindrical and custom extruded profiles to meet diverse applications.
Q2: Can the fender length be customized?
A2: Yes, continuous extrusion allows us to supply different lengths, typically up to 3 meters or longer on request.
Q3: What is the difference between extruded rubber fenders and molded fenders?
A3: Extruded fenders are produced in continuous lengths with uniform cross-sections, suitable for smaller to medium-scale applications. Molded fenders allow larger shapes and higher energy absorption.
Q4: How are extruded fender bumpers installed?
A4: They can be cut, drilled and bolted directly to the structure or mounted with brackets and chains.
Q5: What is the typical delivery time?
A5: Standard profiles are usually available for quick shipment, while custom designs may take longer depending on order volume.
