Advantages of Cold-Formed Steel Construction

Cold-formed steel (CFS) has been gaining popularity in recent years due to its many advantages over traditional materials. This method uses thin sheets of steel that are formed into specific shapes and sizes then assembled to create a structural system. In this article, we will discuss the advantages of cold-formed steel construction and why it is a preferred choice for many owners, occupants, contractors, structural engineers, and architects.

Lightweight and Strong

One of the main advantages of CFS construction is its lightweight yet strong nature. The thin steel sheets are lighter than traditional building materials such as concrete and steel, making it easier to transport and assemble on site. However, despite its lightweight nature, CFS is also incredibly strong and can withstand heavy loads and extreme weather conditions. This makes it a great choice for buildings in areas prone to earthquakes, hurricanes, tornados, and even locations requiring blast design.

Versatility and Flexibility in Design

CFS construction offers a high level of versatility in design, allowing for more creative and unique building designs. The steel sheets can be formed into different shapes and sizes, making it possible to create complex and intricate structures. This versatility allows for integration with other building materials, such as glass and wood, for an aesthetically pleasing design. From replacing traditional wood framing, to 12+ story mid-rise structures, to complex curved structures, CFS can be used to construct an extremely diverse range of structures. A CFS structure also often has more flexibility and redundancy in its design which makes it easier to accommodate changes during the construction process, reducing the risk of delays and additional costs.

Cost-Effective

Compared to traditional construction methods, CFS construction is more cost-effective. The lightweight nature of CFS means that less material is needed, resulting in lower material and labor costs. Additionally, the ease of assembly and shorter construction time also contribute to cost savings. This makes CFS construction a great option for those looking to build on a budget. Recent price increases in builders’ insurance have also pushed some contractors to prefer CFS, as its non-combustible nature results in a significant savings in insurance premiums. This alone can be the deciding factor when deciding between wood and CFS.

Sustainable and Recyclable and Low Carbon Footprint

CFS construction is also a more sustainable option compared to traditional building methods. The steel used in CFS can be made from recycled materials, making it an environmentally friendly choice. American made steel also has a low carbon footprint compared to other construction materials (especially concrete). In 2020, nearly 71% of US steel was produced using low emission electric arc furnaces. Lastly, though the high durability means CFS structures can last longer than wood, they can ultimately be recycled at the end of their lifespan, reducing waste and promoting sustainability.

Higher Building Height Limits

Another advantage of CFS construction is its ability to achieve higher building height limits. Due to its lightweight yet strong nature, CFS building height limits surpass those of other materials. Structures can be built taller than traditional buildings without compromising on safety or structural integrity. This makes it a great option for mid-rise buildings and other structures that require a taller design, while keeping the supporting foundation designs reasonable compared to heavier materials.

In conclusion, cold-formed steel construction offers significant advantages over traditional building methods, making it a preferred choice for many owners, occupants, contractors, structural engineers, and architects. Its lightweight and strong nature, versatility in design, cost-effectiveness, sustainability, structural design flexibility, and higher building height limits make it a great option for a wide range of construction projects.
