Marine Tie Bars System

MARINE TIE BARS SYSTEM Tie Bars are used in port and harbour construction to anchor waterfront structures. Steel grades from 355 to 700 N/mm² in yield strength, and thread diameters from M48 to M162. Different standard designs of articulated joint are available, including swivel plates, captive nuts and ball cages, to ensure the project requirements are fully accommodated. Anchorages can be made compatible with all sheet pile profiles, combi walls and concrete diaphragm walls. For projects using sheet piles, Dextra can also design and prefabricate waling beam systems with waling bolts to provide a complete anchoring system which will ensure full compatibility and consistency with our tie bars systems.
