Many buildings have traditionally used wood or concrete for internal framing systems but steel is increasingly taking over. That’s because steel framing systems offer many benefits over other methods.
Steel framing systems have many applications in construction but they are especially suitable in prefabricated steel buildings, whether for commercial or domestic use. Common applications for steel framing include load-bearing walls, roof trusses and ceiling systems, curtain walls, facades, internal partitions and for internal cladding. Steel framing is now a common choice in many construction projects.
Features of Metal Building Framing Systems from a Steel Structure Company
Steel framing systems are engineered solutions that generally use cold-formed steel, otherwise known as light gauge steel. It is produced by a cold rolling process that forms the required components by passing coils of galvanized steel though rollers. This process ensures the frames are made to exact specifications with high quality and minimal waste.
Cold-formed steel is available in a variety of thicknesses and so is suitable for different applications:
- Thin gauges (0.0147 inches thick) that are used in non-structural applications such as for interior walls that are not load-bearing.
- Medium gauges that are suitable for partitions and curtain walls.
- Thicker gauges (up to ⅛ inch) that are used to support heavier loads and fulfill structural roles.
Benefits of Steel Framing Systems
Steel framing systems are increasingly replacing wood and concrete versions because of their many advantages. They provide the best internal walls for metal building use for several reasons:
- Steel frames give great structural integrity, largely due to the metal’s tremendous strength to weight ratio. This allows more metal building interior ideas with increased usable space and more flexible floor plans since there can be fewer support columns and internal walls due to longer spans being possible.
- Construction time is reduced, with a resulting saving in cost and increased accuracy because of off-site fabrication that avoids delays and other issues at the site. The ability to construct partly off-site in factory conditions helps to ensure high quality control is possible.
- Waste is reduced since frame components are pre-cut to meet precise specifications. The steel is often made partly from recycled materials and is itself recyclable at the end of the building’s life, so the process is better for the environment due to a lower use of resources. This emphasis on sustainability can help the building attain LEED certification as well as meeting other environmental requirements.
- Steel framing, although extremely strong, is much lighter than timber or concrete. This makes it cheaper to transport and easier to handle, so construction is simplified.
- In areas where high winds are common or there is seismic activity, steel framing is able to withstand the lateral forces they cause. Its strength and flexibility mean it is able to dissipate and absorb energy, providing great stability and safety even in extreme conditions. Buildings can be created with a weather-tight and durable envelope that maintains the property’s integrity.
- Compared to concrete and wood framing, steel is a much better long-term prospect. It is resistant to pest infestation and fire, and does not crack, warp or otherwise deteriorate. As a result, buildings may be easier to insure with lower premiums and they tend to have a higher resale value.
- Steel is able to support advanced insulation systems and so contributes to a reduction in heating and cooling costs, which also adds to the material’s sustainability properties.
- Steel framed structures require much less maintenance than those made from wood or concrete. This is due to steel’s resistance to problems faced by other materials and so, by selecting the best quality materials, a building’s life expectancy of 100 years is quite reasonable.
Although steel framing will initially cost more than wood, the long-term benefits of durability, energy efficiency and reduced maintenance ensure that the material is a cost-effective investment. After 7-10 years, the whole life cost of steel framing will fall below that of wood and concrete, and a positive return on investment will follow thereafter.
Effective and Compliant Use of Steel Framing
A steel framing system comprises a number of components:
- Studs to form wall assemblies.
- Members that support structural loads.
- Floor and roof joists and trusses.
- Connectors and fasteners.
Careful planning is needed for successful installation and then precise alignment is necessary to ensure structural integrity. This involves a number of steps:
- Building the frames for walls.
- Adding studs that support fixtures and drywall.
- Incorporating door and window framing.
- Securing the frames to the building’s columns.
- Adding beams and joists where needed.
- Installing plumbing, mechanical and electrical systems.
- Fixing wall finishes such as drywall to the studs.
Steel framing has to comply with industry standards, particularly the specifications set out by the American Iron and Steel Institute (AISI). Local building codes may also add further requirements, ensuring that all steel framing will provide the necessary support.
Once installed correctly, your steel framing is extremely durable but does require some maintenance to ensure its long life. In particular, excess moisture can cause corrosion so drainage systems and vapor barriers need to be inspected regularly to avoid a build up of condensation. Coastal areas and those with high humidity are particularly at risk and protective coatings, which typically last up to ten years before renewal is required, can help to avoid the corrosion of exposed steel. Regular inspections and cleaning will prevent any problems.
As timber prices continue to rise, steel framing becomes an ever more attractive proposition, especially given its many other benefits. As technology continues to make advances, these benefits will only increase so you need to take full advantage of the latest developments.
