Screw piles are a durable and versatile foundation solution. Suitable for use in a variety of projects and condition types, they are screwed into the ground to support the load of a structure. The steel shaft with helical flights bite into the ground, enabling installation without excavation or the use of additional materials to hold them in place. But to ensure the strength, durability, and overall performance of the screw piles used in any project, they have to be made from the best quality materials.
Why Quality Materials are so Important in Screw Pile Production
Structural integrity
The role of screw piles in construction is to transfer the load of a structure into the stable soil deep below. If poor quality materials are used in the production process, they may not have the strength and structural integrity to perform that task. Whether in the immediate or longer term. This can mean structural tilting, foundation settlement, or in the worst case, the complete collapse of the building above.
Corrosion resistance
Most screw piles have a life expectancy in the region of 80 years. This is partly due to high levels of corrosion resistance derived from quality manufacturing. Where sub-par materials are used, however, corrosion can take place, particularly in damp conditions or acidic soils. When that happens, expensive remedial work will usually be required.
Durability and longevity
Obviously, both of the above points indicate that the use of substandard materials within screw piles will impact the overall durability and longevity of the product. And consequently, the build.
Safety
Equally, if using poor quality materials in the formation of screw piles can risk structural integrity and later corrosion, that presents a serious safety concern. If you are constructing any kind of build, you have a duty of care. Firstly, for the people working on your site. Secondly, for the people who will use the structure. By using screw piles made from poor quality materials, you are potentially risking the safety of both.
Compliance
Depending on where you are and what project you’re working on, your build may need to comply with various building codes and standards. Frequently, this means the use of specified materials in the foundation system. Non-compliance can risk structural integrity as well as a whole range of legal issues, and some costly fines.
Sustainability
As a general rule, screw piles made from durable, high-quality materials are more sustainable than their cheaper counterparts. This is because they last longer and require less maintenance. But also, because in most cases, the higher-quality materials equal more responsible manufacturing processes.
Economic efficiency
In the short-term, purchasing lower quality screw piles will almost always be cheaper. However, because they’re not as durable and often require remedial work, it’s a false economy. By investing in higher quality screw piles, you can avoid that later expense.The materials used in screw pile production seriously impact their performance. That’s why at UK Helix we always make sure that the highest quality steel is used in the production of all our screw piles. That way, we can ensure that whatever your project – a garden shed or a large-scale commercial structure, your screw pile foundations will stand the test of time.
