It used to be that extensive, basic facilities like garages and warehouses were the primary uses for steel-framed construction. However, this is no longer the case. Although this is how most people still think of steel frame construction, it is now employed in various sectors such as offices, factories, schools, other public structures, and certain private homes.
Cold-formed steel profiles are made from galvanised sheet steel produced by steel mills. The final profiles for framing are created by rolling sheet steel into the desired shapes. To avoid oxidation and corrosion, the sheets are zinc-coated.
For a wide range of structures, steel framing construction is a viable alternative.
Off-site fabrication of structural steel components, which may subsequently be moved to the building site when needed, reduces on-site labour and lessens the impact of factors that can delay a project, such as bad weather.
Aside from that, there are several benefits and drawbacks to using a steel frame for building manufacturing. Below, you’ll find a list of them:
Steel-Framed Buildings: The Advantages
Compared to brick, concrete, and timber structures, steel frame buildings have the following benefits.
Stability & Longevity
Structural steel components are more lightweight and durable than their wood or concrete counterparts. Weight-bearing steel structures are typically 30-50% lighter than their wooden counterparts. Compared to traditional wood framing, the steel frame construction is more substantial and long-lasting.
There is a wide range of steel studs to choose from, and they may be made to order. Depending on the style and scale of the structure, this means they may be customised to carry specified weights.
Buildings with steel frame structures are less likely to catch fire and are better able to contain a fire should one break out. Structural steel’s ability to resist flame is improved by using flame retardant coatings.
Resistant to Pests and Insects
Wooden frameworks can be a concern if burrowing insects and animals haven’t adequately treated them, but structural steel components aren’t affected.
Skeleton, wall-bearing and long-span framing systems are all structural steel frames.
Framing with a skeleton of steel
Framing the body Multistory structures are typically constructed using a skeleton frame, a framed structure. Incorporating a system of columns and connecting beams supports the structure’s inner floors and outer walls while also transporting loads to the basement. Masonry walls are supported by spandrel beams erected around the structure’s perimeter. The required distance between each column must be determined to arrive at the correct length.
It is possible to join skeleton frame constructions using various steel components and connectors.
Steel Framing for a Wall’s Support
Structural steel members are attached to masonry walls using bearing plates and anchor bolts in a wall bearing steel frame, which includes the installation of perimeter and interior masonry walls. The design and construction of wall-bearing framing depend on the load intensity and span between consecutive supports. To maximise headroom in a structure, lower-depth beams necessitate tighter spacing of the columns and decrease clear floor space area, which is a disadvantage.
Structural steelwork with a long clear span
In situations when traditional beams and columns are not acceptable, Long Span Steel Framing is employed. A lengthy span is at least 12 metres in length. It helps to give flexible floor space, column-free interior spaces, reduced construction time, numerous service installations, and mixed-use of areas. Large industrial structures, auditoriums, theatres, and exhibition halls are familiar places to find it. It is commonly used in larger construction projects requiring higher arches and more weight.
