4 Advantages of Cold Formed Sheet Piling
If you’re looking for sheet pile options, deciding between hot rolled and cold formed sheet piles may not yield an obvious decision. While hot rolled sheet pile has been a staple in the industry for well over a hundred years, cold rolled steel is relatively newer, having been in use since the 70s. While both are integral parts of the pile driving industry, today we’re here to discuss how cold formed steel can positively impact your projects.
What is the Difference Between Hot Rolled and Cold Formed Sheet Pile?
Hot rolled steel is formed when pre-rolled steel beam blanks are heated to a temperature that allows them to be formed into sheets. Cold formed starts in a similar way, with hot rolled steel coil being formed and then run through a mill, which then forms the coil into sheet pile sections. Ultimately, both hot rolled and cold formed sheet piles yield the same steel properties, but their differences come in the way they perform once they’re in use onsite.
It Makes Interlocking Easier
One major drawback of the hot rolled process is that sheet piles can vary from manufacturer to manufacturer, which can make it difficult for contractors to purchase materials from multiple places should the need arise. This requires the fabrication of a transition piece, which can become cost prohibitive or inefficient over time. On the other hand, with most cold formed interlocks functioning in essentially the same way, contractors are given the freedom to move between manufacturers with minimal interruption as the need arises. As the above-mentioned article notes, cold formed steel interlocks work on a “hook and grip” principle, which keeps the pile from being dislodged once it’s been driven.
It Yields Higher Strengths
If you’re designing a structure that requires significant load-bearing capabilities, cold rolling is also the best option for you. The cold rolling process has shown consistently higher payoffs in strength and load-bearing than their hot rolled counterparts, which can provide the ability for harder driving.
It Minimizes Waste and Maximizes Space
One of the greatest advantages of both hot rolled and cold formed sheet piling is its ability to minimize environmental waste. Because loads can be stress tested immediately and sheets can be easily extracted if need be, they reduce site waste. Additionally, because steel sheet piping is a more narrow form of construction, it maximizes the amount of usable space inside the site, making for satisfied occupants.
Whether hot rolled or cold formed steel is best for a given type of project is a debate that will continue to carry on between contractors. But if you’re interested in minimizing waste, easier interlocking, and higher load-bearing capacity, call your local steel supplier. We’ll be happy to discuss the benefits of cold rolled steel and help keep your project on track.
