Steel Tiebacks

A tieback is a structural element, also known as a ground anchor, installed in soil or rock to transfer applied tensile loads into the ground.  Nucor Skyline manufactures several types of high strength steel threaded bars used for excavation support. With multiple manufacturing locations across the United States, Nucor Skyline can supply your North American geotechnical needs easily and quickly.

Cold rolled and hot rolled steel threaded bars are continuously threaded for easy cutting and coupling at any point on the bar. These are both manufactured in the United States, along with many different types of hardware that are used with the threaded bars.

Threaded bars from Nucor Skyline are ideal as tie rods for steel retaining walls. In addition to being the North American market leader in steel sheet piling, Nucor Skyline also manufactures and supplies several types of tie rods. Continuously threaded cold rolled bar is made at our internal facilities. Skyline works with Nucor to supply hot rolled threaded bar. The tie rods supplied by Skyline gives our customers the widest range of choices and best value in the industry.

Tie Rod Bar Systems

When seawalls and retaining walls experience extreme stresses, it is the tie rod bar system that helps keep them steady. Although they remain hidden from sight, steel tie rods keep these structures upright and able to withstand the forces of groundwater, expansive soil pressure, and other destructive forces.

The team at Nucor Skyline understands the critical importance of helping loaded structures stand tall. Our steel systems make it possible for builders to rapidly install, test, and maintain walls that can’t afford to lean, or even collapse. We supply a variety of thread profiles, anchors, and bars which will allow your projects to survive harsh conditions in any environment.

Tiebacks: An efficient and safe solution

Tieback rods are physically sound solutions for increasing the structural stability of walls that would otherwise overturn. In most cases, they are installed horizontally, or at an angle, to link outer structural elements to more solid deadman walls, walers, and deep foundation elements embedded within the ground.

Whereas a standard wall might only be anchored to the ground by its bottom foundations, tiebacks permit the entire structural face to remain rooted using proven principles. Without tiebacks, walls that meet the soil could shift and lean every time groundwater builds up following an extra-heavy rainfall. Seawalls that provide critical environmental protection could fail to prevent erosion and could even allow it.

From keeping the earth firm around skyscrapers to ensuring people can enjoy pristine coastlines for generations to come, sound tieback systems are essential to structural longevity.

How Nucor Skyline Tie Rod Technology Offers Systems that are Permanent

Nucor Skyline manufactures several types of steel tieback rods and anchors that meet the specifications of the Post Tensioning Institute (PTI). Thanks to a tightly managed distribution network and our fabrication facilities, we can supply your geotechnical project needs efficiently to your jobsite.

Impeccable Fabrication Expertise

We specialize in a range of bar types tailored to distinct situations. Our US made cold- and hot-rolled steel threaded bars make cutting, coupling, and other on-site alterations far less time consuming with our continuously threaded design.

A Comprehensive System of Tieback Products 

Our production lines offer a vast hardware selection to complement our threaded bar systems. With a decade of smart engineering and fabrication practice, we can create bars, nut caps, couplers, and washers in a range of styles to accommodate any project. What’s more, our quality controlled manufacturing standards let us satisfy any custom request, including applying hot-dip galvanization, epoxy coating, specialty corrosion protection, and cost-saving modifications.

All Nucor Skyline tie rod and threaded bar systems are designed and tested for consistent performance – even when you can’t see them in action. Why not build using components that meet and often exceed minimum tensile strength requirements so that your project stakeholders, occupants, and users can put their faith in the quality of your work.

Contact your Nucor Skyline representative to find out available grades for the ideal yield strength or discuss how to customize your preferred right-or left-handed threading for seamless anchor installation and error-free construction. With Nucor Skyline, it’s never been simpler to keep walls in place, regardless of how the situations demands you build them.

Build a More Secure Future with Nucor Skyline

High-quality steel tiebacks are just one part of long-lasting construction projects, but they are among the most mission-critical. Working with Nucor Skyline makes it simple to integrate sound engineering principles into your methodology. From helping you select the ideal rod geometry for a particular application, to ensuring you have the knowledge to pre-load and test with confidence, we enable you to create stronger, more reliable structures in the face of constraining requirements.
