China Heavy Duty PE Polyethylene UHMW HDPE Marine Dock Bumper

Heavy Duty PE Polyethylene UHMW HDPE Marine Dock Bumper

Fender panels distribute reaction forces to provide low hull pressures and cope with large tidal variations. They can also be designed to resist line loads from belted ships, or even point loads in special cases. Optional lead-in bevels reduce the snagging risk, whilst brackets (where required) provide highly secure connection points for chains. Closed box designs are used almost exclusively - all fully sealed, and pressure checked. Corrosion protection is provided by high durability C5M class paint systems to ISO9001, and additional corrosion allowances can be designed where required.
