All steel wall and roof frames constructed by Central Avenue Homes are covered by a professional indemnity policy that exists for 25 years.
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 is backed by BHP’s 75 performance statement
Every roof is designed by specialists in their field and certified by a structural engineer.
Steel is a known quantity. So when a roof is designed and engineered, they know what variation 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 from a compressed air nail gun.
Utilising a steel roof allows far less tolerance or errors in the construction to plate high. The main part of the roof is constructed off site to engineered shop drawings and brickwork not 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 the ceiling, so, 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 built with a steel roof can offer open space designs and feature ceilings such as bulkheads and coffered ceiling recesses.
Steel roof frames are generally built in a factory and erected on site in following the structural engineers certified drawings.
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 fix the problem. You’ll never need to apply chemical treatments to a steel roof structure.
Steel roof frames keep their shape immediately when they are loaded, this means they will not shrink or warp as they dry out. This results in less maintenance to cornice cracking.
The lines on both the roof and the ceilings are generally straighter than with timber.
All ceilings are fixed with screws and are not prone to what is commonly known as ‘popping’ 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 because a steel frame roof is grounded.
Steel is one of the most recycled materials on earth, and 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 peace of mind knowing your house frame is 100% termite proof. That’s value for money in anyone’s language. TRUECORE® steel used in residential house frames comes with a 50 year warranty* backed by BlueScope .
Termites can still attack the rest of your home so steel frames don’t make that much difference.
There is nothing more catastrophic as the destruction of the frame of your house. 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.
There is no evidence that termite nests, excrement (waste), heat or moisture can damage a steel frame in any way.
Steel frames are noisy – popping, creaking and groaning as the temperature changes.
Steel frames are no more noisy than timber frames and there is some evidence to suggest the opposite. Studies conducted by the CSIRO found that “most occupants of homes with steel frames either
- reported no sound emitted from the frame
- 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.
Steel framing expands and contracts at rates similar to cornices and plasterboard.
This means it is highly unlikely there will be cornice cracking problems due to frame movement.
Steel frames perform worse in a fire.
Steel is non-combustible and does not add fuel to the fire. The elimination of combustible material, such as timber frames, helps prevent 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.
