Since cold-formed steel (CFS) buildings are noncombustible, exceedingly robust, and relatively inexpensive to install, they have monopolized the market for internal partition walls in commercial structures that do not bear any load. Building professionals are increasingly turning to CFS for structural applications in a wide variety of residential, commercial, and industrial structures as a result of recent advances in technology, such as pre-fabricated systems.
In point of fact, cold-formed buildings have increasingly become the choice of material for construction from across the country, where sensible developers are concerned with maximizing their investment returns. This trend is expected to continue for the foreseeable future.
CFS doesn’t really contain any components that could contribute to the spread of fire, and as a result, it is not combustible. In comparison to the ignition point of wood, which is between 400 and 500 degrees Fahrenheit, its melting point is 2700 degrees Fahrenheit. It not only does not burn, but its melting point is also extremely high.
Particularly compared to the use of wood, the use of steel in construction projects results in significant savings for building owners on their annual property insurance premiums. These premium reductions can be in the hundreds of dollars. Why does it cost less to insure cold-formed buildings that are made of steel? One of the primary explanations for this is that wooden structures are far more prone to catching fire, particularly when they are still in the process of being constructed and before any components that provide fire protection have been installed.
CFS is approximately twenty percent more robust than hot-rolled steel, as stated on ScienceDirect.
The strain hardening which happens as a result of the rollers being compressed contributes significantly to the overall strength of CFS. The high pressure that is used during the process of cold rolling makes the steel immune to rot, mold, and mildew, as well as damage caused by insects, termites, as well as other vermin.
Because of its long-lasting qualities, CFS is an excellent choice for building materials. Steel that has been cold-formed buildings does not crack or shatter, and it also does not expand or contract in response to changes in the amount of moisture it contains. In addition, steel studs do not bend, twist, or bow under tension.
When you take into account the inherent sturdiness of the structure as well as the findings of research conducted by the NAHB that demonstrated that the zinc coating on steel framing components could guard against corrosion for thousands of years, you have one exceptionally solid building!
The use of cold-formed steel can result in cost savings in a variety of different areas. The utilization of cold-formed steel leads to decreased insurance costs for builders as well as owners because it helps to reduce the likelihood of fires occurring. In addition, the use of panelized cold-formed steel in construction processes results in quicker construction cycles, which enables constructors to finish projects that are framed with steel several months sooner than they might with some other framing materials. In conclusion, the traditional use of wood for framing results in a significantly higher amount of waste material than the use of cold-formed steel.
Long-term durability, as well as amazing service life, can be achieved with steel structures that are appropriately planned and constructed. Building codes and industry standards mandate that steel-framed structures either be designed to bear corrosion or be safeguarded against it in situations where corrosion may reduce the structure’s strength or capability to function properly. Depending on the extent of such exposure conditions, steel framing can be protected using barrier paints or even other coatings that are placed on site or during the manufacturing process, or it can be galvanized, which involves coating with zinc.
Steel with a coating of zinc
This is typical for cold-formed steel framing — it will last for a significant amount of time beyond the life of a structure when it is erected and insulated in the correct manner. The zinc coating “sacrifices” itself to corrosion in every region in which the underlying metal is made vulnerable in order to protect the steel that lies beneath it. CFS is particularly ideal for usage in the high-demand structural configurations of configurations that are featured in the mid-rise building as a result of its resistance to corrosion.
Easy on the Stomach
Because Cold-Formed Steel is significantly lighter than that of the majority of other types of cold-formed building components, it is feasible to considerably lower the amount of weight that the structure’s bearings have to support. When compared to the much bulkier 45psf concrete material that really was initially being used for the project, the bearing weight of such Hilton Garden Inn that was being designed in Durham, North Carolina, was able to be reduced by 80% because of the use of Sigma Stud. This decrease in weight made it possible to have a foundation with less strength, which ultimately resulted in significant cost savings.
Another advantage offered by CFS is that it speeds up the actual building process.
Because cold-formed steel is relatively lightweight, it is simple to ship and handle. In addition, CFS products are rolled-formed and into the precise shapes and sizes necessary, and comprehensive labeling of all of the pieces ensures that assembly will be both quick and error-free. Because it is lightweight and adheres to uniform manufacturing standards, CFS is perfect for trusses as well as panels that can be quickly fitted with a reduced number of framers.
The fact that CFS panels come with pre-punched holes makes steel framing even more efficient in terms of building time. This makes it possible for electrical lines, plumbing, and mechanical systems to be quickly installed.
