Cortek Light Gauge Steel Framing FAQ's

What are your frames made from?

Our framing systems are manufactured here in Australia using quality materials including high tensile and galvanised steels.

Do you install your frames?

No, Cortek is a supply only manufacturing company. Typically, carpenters are used to erect steel frame systems.

Our pre-fabricated framing systems are simple and easy to install with layout plans, fixing locations and details supplied to the builder and installer.

If required, we can suggest preferred and experienced installers. We have been working in with preferred installers for over 18 years – together we combine our expertise to provide a quality and superior system for our clients

What types of framing do you manufacture?

Our core products are pre-fabricated walls, roof trusses and floor joist framing solutions using light gauge steel.

We can pre-fabricate framing solutions for various other applications including bulkheads, balustrades and other custom architectural features.

Cortek is also the manufacturer and supplier of the Smart Hob system – a pre-fabricated permanent hob formwork alternative. Learn more about the Smart Hob system.

Are you Australian owned and operated?

Yes! Cortek is Australian owned and operated. Our factory and offices are located in Melbourne, Victoria.

Is light gauge steel framing faster to install?

This is project dependent, but the speed and ease of installation is one of the key benefits often highlighted by project managers who use steel frames.

LGS framing is engineered with precision and pre-fabricated to your exact specifications so it’s fast and easy to install. It is straight and true so less on site adjustments are needed. It also comes complete with pre-punched service holes which means follow-on trades can complete their individual stages faster. As a result of the above, many builders we have worked with have reported significant time savings compared with traditional timber construction.

Is steel framing more expensive than timber?

When comparing the overall price of a project, steel framing is the more cost-efficient option.

Lightweight steel can be easily managed and installed on site, which means the job can be completed faster. Depending on the size of the project, a reduction in construction times can add up to significant savings in labour. Unlike timber, steel is strong, straight and true, meaning it’s less likely to be damaged or to have discrepancies when installed, saving you on materials costs. Once installed, there is no need to straighten or plane walls made from steel.

Do you include roofing battens and yellow tongue flooring as part of your framing systems?

No, Cortek are experienced manufacturers of walls, trusses and joists systems. All floor linings and roofing battens are supplied and installed by your preferred and qualified contractors.

Do you provide cladding services?

No, we specialise in the pre-fabrication of light gauge steel framing alternatives. However, we work in partnership with multiple contractors to provide complete solutions for our clients. We are more than happy to recommend preferred contractors for this service.

How far can your steel trusses span?

All trusses are designed, engineered and fabricated to the relevant building design.

There are many design considerations that are evaluated, such as external wind pressures, trafficable loads, plant loadings, abseil/safety point loads, mechanical services, solar panels, skylights etc.

Do your framing systems provide structural steel where required?

Cortek can provide structural steel as supporting elements to a light gauge steel structure. Cortek is fully accredited to design and engineer such requirements.

Are your steel frame systems engineered and certified?

Yes, all our framing systems are signed off by registered engineers and are compliant with engineering certification to BCA code specifications.

What are the advantages of pre-fabricating or why should I pre-fabricate?

It will depend on the project, but the use of pre-fabrication substantially reduces the labour required on site whilst offering significant time and cost saving advantages. It can also eliminate the need for scaffolding and cranage. By utilising the power of pre-fabrication, it is our aim to help our clients deliver their projects faster and more efficiently by removing design and construction limitations.

How much does your framing cost or what is the square metre rate for your framing?

As all of our framing is highly customised to suit your project requirements, we don’t have a one size fits all pricing approach. Each project is individually reviewed on their own merits to meet specific site and design requirements.

Please contact us on 1300 782 950 or email sales@cortekframing.com.au to discuss your project – we will put together a detailed quotation explaining the scope of the project, engineering details as required and mark-up plans.

Is light gauge steel framing strong enough for structural walls and multi-level buildings?

Yes, steel is strong by nature and we use steel that is manufactured to meet Australian Standards. Our framing systems are engineered to meet the relevant structural requirements of the National Construction Code and are regularly used for wall and roof framing across a vast array of single-storey and multi-level developments as applicable.

Can light gauge steel framing be used in areas with a high bushfire risk?

Steel framing can help you achieve compliance when building in high-BAL areas or even flame zone areas. And importantly, a steel frame is non-combustible, which means if a fire does occur in the building it will not contribute to the spread of the flames or smoke.

Is steel framing termite resistant?

Fabricated steel frames are by nature termite, borer and fungus proof and do not need to be treated with insecticides. Steel frames satisfy the requirements of the National Construction Code for termite resistant materials.

As per the building code and applicable areas, other additional termite barriers may need to be installed to protect other building materials on the project.

How can I be sure of the quality of pre-fabricated light gauge steel framing?

Our pre-fabricated frames are detailed and engineered precisely to the relevant AS codes and accurately utilising the latest design software. Framing is manufactured by our experienced team to ensure quality control.

We only use steel that complies with the applicable construction codes and with all Australian Standards. Steel is straight and true and will not shrink or warp in the future.

Will a building experience much movement when steel framing is used?

Steel frames will not shrink or swell when installed as they do not go through a process of absorbing moisture and drying out. In the longer term, buildings constructed with steel framing are less likely to experience windows and doors that stick and jam as the light gauge steel will not twist, shrink or warp. Steel framing does contract and expand in response to temperature changes, but it does so at a rate like other materials commonly used in buildings and is unlikely to cause any cornice cracking or noise.

How do I fix off to steel frame walls? (e.g. hanging items, architraves etc.)

Steel framing is widely used in commercial fit-outs for partition wall framing. There are no typical practices used for fixing and mounting items to a steel framed wall. The use of a harden fixing nail, screw or construction adhesive is most common.

We recommend speaking with relevant fastening manufacturers for suitable fixing applications and specific design consideration.

Project Questions

How much design flexibility will I have if I choose to work with steel frames?

A lot! Pre-fabricated LGS frames can be manufactured to the exact design specifications of almost any residential and commercial building project you can think of. The high strength-to-weight ratio and flexibility also allows for wide spans, open spaces and architectural rooflines which may not be otherwise possible when traditional timber or structural steel is used.

What services do you provide as part of my project?

We work with our clients from start to finish, developing smarter pre-fabricated alternatives. Our services include in house design, shop detailing, engineering, fabrication and delivery.

What type of projects do you work on?

The majority of our projects are multi-residential developments, expanding into commercial, educational and community aged care sectors. The sizes of our projects also vary although we typically provide framing solutions for mid-rise projects.
