Ribbed Pneumatic Fenders
Hongruntong Marine specializes in manufacturing high-performance Ribbed Pneumatic Fenders designed for extreme marine operations. Our ribbed-type pneumatic marine fenders feature an innovative surface design that significantly enhances grip stability and prevents slipping during vessel-to-dock or ship-to-ship operations. Engineered with reinforced synthetic rubber and advanced textile cord layers, these fenders deliver exceptional energy absorption, outstanding abrasion resistance, and extended service life even in the most challenging marine environments.
As an ISO 17357-1 certified manufacturer, Hongruntong Marine guarantees that every ribbed pneumatic rubber fender meets international quality standards and performance requirements. Our products are specifically designed to handle harsh conditions including saltwater corrosion, UV exposure, and high-impact berthing scenarios.
