Frequently Asked Questions

Why SFS’ light gauge steel framing?

Very simply, a light gauge steel frame is a high quality product. It represents value for money and brings peace of mind. A light gauge steel frame is light and strong: it will not burn; it is termite, borer, and fungus-proof; and it will not shrink or warp. It is environmentally responsible, low on life cycle energy usage, recyclable and saves timber resources. A SFS’ frame is between 33% and 50% of the weight of a comparable timber frame, with a far higher strength to weight ratio. Steel features one of the highest strength to weight ratio of any conventional building product.

Steel is incredibly accurate with tolerances in the 10ths of a millimetre, not in 10s of millimetres. Your window and door openings will be precisely placed, perfectly square (or perfectly tapered depending on your design) meaning fitting will be faster and easier. Because steel doesn’t warp, twist, bow or settle you will experience less ‘nail pops’ requiring rectification. You will also experience drastically reduced instances of doors and windows sticking as the house settles, because a steel frame never ‘settles’, its engineered to maintain its dimensions for the lifespan of the building. ​

Steel is 100% recyclable (in its purest sense) and has a virtually infinite life span; it’s the most recycled product on the planet. Termite treated timber is un-recyclable (straight to landfill) and almost all other timbers are only down-cyclable.

Steel is 100% termite PROOF, requires $0 of termite treatment and $0 of ongoing termite maintenance.

Steel is 100% non-combustible, it will not burn or ‘char’ and it will not contribute to a fire, or the spread of fire. In a bush-fire, ember attack to a steel house frame and roof space will not ignite the frame.

What underlies the quality of a light gauge steel frame?

Light Gauge Steel is an engineered product, not an organic one. Being engineered means movement over time is eliminated, as a steel frame will not settle like other products.

BlueScope Steel, a quality-accredited producer to the appropriate National Standard Specifications, produces TRUECORE® steel in a Light Gauge Steel (LGS) Frame Solutions frame. The components are precision manufactured and assembled to very tight tolerances using advanced techniques. SFS uses the most advanced framing system available in the world today, combining design and engineering software and an automated roll former to produce frames, trusses and joists quickly and accurately. Strength and performance are engineered into the frame, allowing 3S Super Steel to provide the best possible product to its customers.

What’s the warranty on TRUECORE® steel?

TRUECORE® steel used in SFS’ wall frames and trusses come with a 50 year warranty* from BlueScope Steel. A great reassurance in anyone’s book! For more information on the 50 year warranty, including the terms and conditions, visit BlueScope Steel’s warranty website.

Will a light gauge steel frame rust?

SFS’ LGS frames are made of steel protected against corrosion by a hot-dipped metallic coating of a zinc-aluminium alloy. In external applications such as roofing, these products are exposed to the elements and have excellent durability, so in less exposed applications such as inside the building envelope they weather more slowly. Where there are cut edges, the galvanic action, or sacrificial protection, of the coatings protects the exposed steel edge against corrosion.

Is a steel frame noisier than other stud frame buildings?

No – this is one of the most ‘popular’ myths of light gauge steel framing. 3S Super Steel’s light gauge steel frames are no noisier than other stud frames and there is some evidence to suggest the contrary. Studies conducted by CSIRO found that “most occupants of homes with steel frames either reported no sound emitted from the frame or said that if it did, it was not a problem”. In fact, some volunteered that there was less noise than previous timber framed houses.

Steel expands and/or contracts as the temperature changes. Is this a problem?

In a properly constructed and insulated home by 3S Super Steel, thermally induced movement is not an issue. Steel is engineered, inorganic, will not rot, warp, twist, bow, shrink or settle. There will be far reduced instances of plaster or cornice cracking because steel doesn’t change state during its lifespan, which means it is highly unlikely that there will be noise, and in fact, because a steel frame doesn’t settle over time you enjoy LESS issues with movement such as sticking doors, windows and so on.

Termites can still attack the rest of a home so do steel frames make much difference?

The truth is there is nothing as catastrophic as the destruction of the primary structure of a house – the frame. Destruction of the frame by termites can be silent and invisible to the eye. Rectification of the frame can require complete replacement of other building components such as plumbing, electrical, plasterboard, skirting, architraves, kitchens, bathrooms, tiling and painting. However, SFS’ LGS frame is 100% termite-proof, ensuring no damage at all is done to the frame of the home through termites.

Can the customer erect a house frame?

Sure! The customer can install our system. Panels are easily handled and are clearly identified for assembly, with pre-punched electrical and plumbing service holes. Roof trusses are easily identified and easily secured to support the walls. Ceiling and roof battens are easily fixed to the trusses.

You don’t need to know how to be a carpenter to erect a steel frame for your house. You require far less carpentry skills to construct a LGS frame compared to constructing timber frame as you don’t need to deal with the issues of wood warping, twisting and shrinking.

Will I be able to renovate later down the track with a steel framed house?

Yes. SFS’ framing allows for larger spans, meaning a home can often be designed without interior load bearing walls. This makes alterations easier without affecting the structure in any way. Furthermore the existing steel structure will remain straight and true regardless of its age, making the job of lining up the extension easier than for conventional timber framing.

How much flexibility do I have with design?

Freedom of floor plan and architectural style is practically unlimited. SFS can produce almost any 1 to 3-storey home design seen in the Australian market today, as well as being the first (and so far only!) company in Australia to construct a LGS 4-storey apartment building frame. Furthermore, it is possible to produce designs in steel that are difficult with other materials. By taking advantage of this feature, the owner can often build with less expense than by using more conventional materials.

Have steel framed buildings been proven over time?

Yes. In Australia, steel structure has been used successfully in housing since the early 1950s. The Australian steel framing industry has a well-earned reputation for being highly innovative. SFS’ LGS framing represents the results of years of research, testing and product improvement. It is a thoroughly engineered product. In responding to the needs of the Australian customer, the steel framing industry in Australia leads the world with its technology. Don’t forget that steel frames have been used in commercial buildings for many years because of their superior attributes.

How does a steel frame perform in a fire?

Steel is completely non-combustible, doesn’t burn or “char” and confirms to any and all non-combustibility requirements. Being non-combustible means the frame will not contribute to the fire or its spreading, and will not release smoke and carbon dioxide such as will happen with a timber frame. We’ve never seen steel used in a bonfire or BBQ! ​

Smoke and heated air and/or asphyxiating gases are responsible for about 75% of fatalities in house fires. Steel frames will not burn. It will therefore not contribute. Steel releases no gasses or VOCs during its life. This has been recognized by The Healthy Home Institute as a desirable feature for steel frames. Electrical faults cause many fires in wall cavities. An electrical fault cannot ignite a steel frame. If fire gets into the ceiling and ignites timber trusses it can spread very rapidly to the rest of the house. In a bushfire the point of ignition is often the roof cavity when burning embers are blown in under the eaves or tiles. House fires have been known to break through ceilings into the roof cavity. A steel wall frame or roof truss made by SFS cannot be ignited in either of these ways.

Will a light gauge steel frame perform in any climate?

Yes. Not surprisingly steel is the preferred framing material in the extreme climate of North West Western Australia, for example, where temperatures can vary more than 40 degrees Celsius in a single day.

Will my builder charge more for building a steel frame?

Competitive pricing is generally available from progressive builders for standard house designs. Progressive builders are aware that steel frames are the way of the future, and are generally prepared to quote competitively: a premium product at a competitive price.

Do homes with steel look different?

Yes, they look better. Walls, ceilings and roofs do not have ripples or bumps in them and there are no “nail pops” in the plasterboard linings. Roofs of steel-framed homes do not sag over time, even under concrete tiles, so the finished job continues to look good. Steel house frames will not change or move over time, so gaps will not open up letting air in. Insulating products work by creating a barrier between temperatures. Over time, a frame which can settle and move will create openings, which will allow air to travel through, thus rendering insulating products far less affective. Steel will not settle over time allowing other complementing products to continue performing how they were designed and specified. In fact because of 3S Super Steel’s steel’s strength, you can design your home with larger open spaces whilst the exterior looks like any normal home, only better!

Does lightning strike affect a 3S super steel home?

No. Because steel is a positive conductor to the earth. The energy is conducted straight to the ground and is not released destructively within the frame as in conventional framing or cladding.

Is a light gauge steel frame safe when exposed to a live electric wire?

Yes. LGS frames are safe because they are earthed. It is a requirement that all new housing be fitted with circuit breaking safety devices, so there is little chance of you touching anything live. A broken or pierced wire in a timber frame can remain live and leaking current can cause troublesome faults and fire risk.

I am a builder. Why should I build in steel?

Steel frames represent the future of house framing. Continual product improvements and consumer awareness means that demand for steel-framed homes will keep increasing. People are more conscious than ever of the ever-increasing threat from termites. You can build the major termite management into the building, rather than add it on with zero maintenance required, ever. A SFS house is a quality product that delivers to the customer long-term peace of mind and cost savings. Call backs are reduced and your reputation can be enhanced. ​

Although steel frames require slightly different techniques, they are quick and easy to erect. A 3S Super Steel steel wall is straight and true and has continuous nogs and flush connections, meaning cladding materials attach faster and easier. Because steel has consistent strength and complies with strict standards and tight tolerances, every stud is a good stud. LGS frames are lightweight and easy to handle, time is not lost sorting to select suitable pieces, there is no need to straighten framework on-site, and wastage of material is reduced and there is very little scrap on site. Builders will appreciate the lightweight frames being faster and easier to erect. A 7.5-metre wall frame can easily be carried and installed by two men; trusses can be lifted into place by hand.

Does a steel frame interfere with radio or television reception?

No. Electro-magnetic waves can diffract around steel as easily as timber. Waves pass through the spaces between the studs, allowing the use of all household appliances without any interference. Performance is no different to any other building.

Will light gauge steel framing affect the air quality inside my home?

Since steel frames do not need to be treated for termites, this makes your home a resin and chemical free environment. As a steel frame doesn’t sag over time, gaps in the frames aren’t opened up, therefore letting in less dust.

Does a steel frame interfere with wi-fi reception?

Steel framing is used widely all over the world. Australia is now catching up. There have never been any reports of interference and there is no reason why this should occur.

Can I hang pictures on my walls?

A heavy weighted picture, which will require a bolt or hanger to be used, can be screwed straight into a stud. Studs are easily located with magnets.
