As an expert in the field of construction, I am often asked about the differences between structural steel and formed steel. Both are commonly used in building construction, but they have distinct characteristics that set them apart. In this article, I will explain the advantages and differences of these two types of steel and how they are used in construction projects.
What is Structural Steel?
Structural steel is a type of steel that is hot-rolled, making it thicker, stronger, and heavier than cold-formed steel (CFS). It is commonly used as the main structural element in buildings due to its robustness, durability, recyclability, and cost-effectiveness.Structural steel is made from iron that is converted into beams with a cross-sectional profile to give it additional rigidity.
What is Formed Steel?
Cold-formed steel, on the other hand, is also made from iron but is converted into thin strips and cooled. The cold-rolled steel is then formed to the desired thickness and a protective coating is applied. This process results in a thinner and lighter material compared to structural steel.Advantages of Structural Steel
One of the main advantages of structural steel is its strength. Due to its hot-rolled process, it can withstand heavy loads and has a high resistance to bending and twisting.This makes it an ideal choice for high-rise buildings or structures that require extra support. In addition to its strength, structural steel also offers excellent durability, affordability, ease of maintenance, and sustainability. It can withstand harsh weather conditions and does not require frequent repairs or replacements. It is also recyclable, making it an environmentally friendly option for building owners and designers.
Advantages of Formed Steel
While not as strong as structural steel, formed steel has its own set of advantages. One of the main benefits is its lightweight nature, which makes it easier to transport and install.It also requires fewer studs due to its strength, allowing for more flexibility in design. Formed steel is also known for its durability, as it does not shrink or split, absorb moisture, or deform. It is also resistant to termites and fire, making it a safe and reliable choice for building construction.
Differences in Cost
The cost of structural steel and formed steel can vary depending on the project. In general, structural steel is more expensive due to its thicker and heavier nature. However, it offers more strength and durability compared to formed steel. A study conducted on a 5-story, 49,900 square foot mixed-use apartment building showed that framing with structural steel only cost 0.92% more than using light wood.This shows that while structural steel may have a higher upfront cost, it can provide long-term cost savings due to its durability and sustainability.
Choosing the Right Steel for Your Project
When deciding between structural steel and formed steel for your construction project, there are several factors to consider. These include the type of building, budget, design flexibility, and desired strength and durability. In general, structural steel is a better choice for high-rise buildings or structures that require extra support. Formed steel, on the other hand, is suitable for smaller buildings or structures that do not require as much strength.In Conclusion
In summary, both structural steel and formed steel offer excellent structural options for building construction. While they have their own distinct characteristics and advantages, they both share common performance characteristics such as durability, strength, affordability, ease of maintenance, and sustainability. As an expert in the field, I highly recommend considering the use of steel in building construction.Its many benefits make it a top choice for building owners and designers looking for a reliable and cost-effective material. Whether you choose structural steel or formed steel, you can be confident that your building will have a strong and durable foundation.
