All steel wall and roof frames constructed by Central Avenue Homes are covered by a professional indemnity policy that exists for 25 years, regardless of whether the engineer certifying the job is practicing or solvent
Timber is only warranted for the time offered by the builder, usually 6 years. Some offer lifetime warranty, however that is only valid if the builder is trading and solvent.
Material backed by BHP’s 75 performance statement
Each roof is specifically designed by specialists in that field and certified by a practising structural engineer.
Steel is a known quantity and, as such, when the engineering principles are applied we know what deviation will occur when the roof is placed under load
All connections in a roof are positive (i.e. generally tek screws or welds) a timber framed roof is generally nailed together with mild steel nails driven from a compressed air nail gun.
Utilising a steel roof allows far less tolerance in the construction to plate high. The main part of the roof is constructed off site to shop drawings and brickwork out of square or out of level will not accept the trusses.
Strong, durable and non-combustible.
A steel framed roof will not burn or transfer fire through ceiling, by using a steel framed roof, you considerably reduce the flammable material in your home.
Easy and fast to erect
A steel framed roof is strong and lightweight, and can offer excellent spanning capability. House designs using a steel framed roof can offer open space designs and feature ceilings such as bulkheads and coffered ceiling recesses.
Cannot be eaten by termites
If your home has ever been under attack from termites or borers, you’ll know the emotional and financial costs to rectify the problem. You will never need to apply chemical treatments to a steel roof structure.
Steel roof frames attain their shape immediately when they are loaded, this means they will not continue to shrink or warp as they dry out. This results in less maintenance in relation to cornice cracking and the like.
The lines on both the roof and the ceilings are generally straighter than with timber and those lines are for the reasons mentioned above.
All ceilings are fixed with screws and are not prone to what is commonly known as ‘popping’ which is caused by movement of the ceiling frame.
If a steel roof structure is struck by lightning, it effectively acts as a lightning rod, transferring the current into the earth (a steel frame roof is grounded).
Steel is one of the most recycled materials on earth, all steel made by BlueScope Steel includes recycled steel in it’s manufacture. 100% of your steel roof can be recycled. – Courtesy BlueScope Steel
Some Myths Busted about steel framed houses – Courtesy Truecore® Steel
Steel frames don’t provide value for money.
The truth is, there is nothing as valuable as securing your family’s biggest asset. A house frame made from TRUECORE® steel provides the ongoing peace of mind you receive from knowing your house frame is 100% termite proof. That’s value for money in anyone’s language. The fact that only TRUECORE® steel used in residential house frames comes with a 50 year warranty* backed by BlueScope just about says it all.
Termites can still attack the rest of your home so steel frames don’t make that much difference.
The truth is, there is nothing as catastrophic as the destruction of the primary structure of your house – the frame. Destruction of the frame by termites can be silent and invisible to the eye. Rectification of the damaged frame can require complete replacement of other building components such as plumbing, electrical, plasterboard, skirting, architraves, kitchens, bathrooms, tiling and painting.
Termites can damage steel frames in ways other than eating them.
The truth is, that there is no evidence that termite nests, excrement, heat or moisture can damage a steel frame in any way.
Steel frames are noisy – popping, creaking and groaning as the temperature changes.
The truth is, that steel frames are no more noisy than timber frames and there is some evidence to suggest the contrary. Studies conducted by the 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 no problem”. In fact, some subjects volunteered that there was less noise than previous timber framed houses.
Steel frames expand more when they heat up, causing cornices to crack.
The truth is, steel framing expands and contracts at rates reasonably similar to those of other building materials, such as cornices and plasterboard.
Which means it is highly unlikely there will be cornice cracking problems due to frame movement.
Steel frames perform worse in a fire.
The truth is, steel is non-combustible and does not add fuel to the fire. The elimination of combustible material, such as timber in frames and roofing, can have a tremendous influence on preventing the ignition of a fire. It can also slow the speed of a fire, reduce the intensity and potentially reduce damage and cost caused by fire.
