Q: Why should I build in steel?
A: Steel is the product to use for the long term investment of your home. It is lightweight and strong, won't burn, is termite and borer proof and won't shrink, warp or twist - so your home is maintained for the future.

Q: Is steel framing expensive?
A: Innovative frame technology now means steel frames for standard house designs can be priced competitively with other quality framing systems.

Q: Can a house frame be erected by the customer?
A: Almost all systems on the market can be installed by the customer. Indeed Rainbow Building Solutions does supply frames in kit form specifically for the do-it-yourself owner builder. Panels are easily handled and are clearly labelled for assembly, with pre-punched electrical and plumbing service holes. Roof trusses are labelled and easily secured to support the walls. Ceiling and roof battens are easily fixed to the trusses.

Q: If I use a steel frame how much flexibility do I have with design?
A: Rainbow Building Solutions can produce almost any one or two storey home design seen in the Australian market today. Furthermore, it is possible to produce designs in steel that are difficult to replicate using other materials. By taking advantage of this feature a home owner can often build with less expense than by using more conventional materials.

Q: Can I build on piers or a concrete slab?
A: Either. Steel framing can be fixed directly to a concrete slab, or to steel flooring systems on brick, concrete, or steel piers.

Q: I have heard that steel frames are made of thin steel. How do I know they will be strong enough?
A: The properties of steel are known and consistent, and conform to Australian standards or their equivalent. Steel framing components are designed around those properties. Rainbow Building Solutions' systems use high tensile steel components and appropriate jointing methods, and are engineered to pass strict performance tests.

Q: Steel expands or contracts as the temperature changes. Is this a problem? Will the frame be noisy?
A: A steel frame in a properly constructed and insulated home, thermally induced movement and noise is no more likely than with other materials. Steel framing expands and contracts at rates not too dissimilar from other materials, which means it is unlikely that there will be noise or cornice cracking problems.

Q: Is a steel frame safe when exposed to a live electric wire? What about lightning?
A: Correctly installed steel frames are safe because they are earthed and it is a requirement that all new housing be fitted with circuit breaking safety devices. Lightning has less effect on a steel framed home as the steel creates a positive earth allowing the energy to conduct straight to the ground.
