Tie Rods – Connection Rods

Tie rods can be placed between sheet piles or concrete walls for port extensions and manufactured from round steel bar with forged or threaded ends that allow a variety of connections to be made to sheet piles, tubes, H-piles, combi-walls and diaphragm walls.

* As per BSEN-10025, yield and tensile vary depending on nominal bar size.

The choice of steel grade depends on a number of factors, whilst the higher strength steel will always produce the lightest weight anchor this may not be suitable for stiffness requirements, onsite welding or lead-times. Other grades of steel are available please contact us to discuss further.

Depending on diameter and length required, our tie bars are manufactured using selected fine-grained steel, high strength low alloy steel or quench and tempered steel. The choice of steel is dependent upon your specific project requirements but the above minimum properties will be met.

All tie bars and components are manufactured to a quality system audited and accredited to ISO 9001 and meet the requirements of EN1090 and are CE marked.

Corrosion Protection / Surface Finish

Marine structures inherently operate in aggressive environments and selection of robust protection systems for tie bars is key to the longevity of a structure. It is very important to consider the corrosion protection of the anchors at design stage and of particular importance is the connection to the front wall as the anchor is typically subjected to the most aggressive environment at this point and this is the most common area of failure for an anchorage.

Our tie rods can be delivered without any specific surface finish when considering sacrificial thickness as specified in EN 1993 Part 5. In this case, rod shaft and thread size are increased in diameter to allow for corrosion steel loss during the life of the structure. Therefore, no additional coating is required. However, other alternatives are available to enhance corrosion protection, such as bituminous tape, paint or hot dip galvanization, depending on the project design and requirements.
