Design FAQs

You should check with your local council for regulations on fences around pool areas. Particular care needs to be taken if COLORBOND® steel is to be installed within the 'splash zone'. Both salt and chlorine may have a corrosive effect on the COLORBON...

Yes, though for detailed availability you should refer to your local BlueScope Lysaght branch or distributor. Generally it is sold as stock lengths of 7500mm. Please contact us for more information....

Yes, it can. This means the support spacings can be increased. Please contact us for more information.

Yes. However, specific fixing requirements will need to be met. Please contact us for more information.

Steel is a superior product for long term investment, with the added advantages of being light, strong, non-combustible, is termite and borer proof and will not shrink or warp. Steel framing has the durability and structural integrity to easily outl...

Yes. Because of the unique assembly systems, additions are relatively simple to make. Furthermore, the original steel structure will be straight and true regardless of its age, making the job of matching up the addition easier.

COLORBOND® steel fences should not be installed within 1 kilometre of marine, severe industrial or other corrosive environments.

Yes, it can. Consideration should be given to minimise the sag and thus the support spacing should be limited to 900mm spacing and it may be necessary to have additional fasteners in the pans.

LYSAGHT BONDEK® can be used as formwork and as a reinforcement in composite slabs. It can be used in a wide range of building construction including steel, concrete and masonry framing system with a minimum ground clearance of 450mm. It is typic...

No.The flange dimensions and flange shape do not allow these profiles to lap with each other. Thus in projects where there is to be an extension from an existing building there will need to be some attention to detailing to allow the connection to b...

Yes. The new SupaPurlin profile has added features (web stiffeners) that will increase its performance in floor applications. The SupaPurlin profile can also be used in all other applications where the traditional purlins have been used.

The standard heights are 1200mm, 1500mm, 1800mm and 2100mm.

You will need 2 LYSAGHT® fence posts, 3 LYSAGHT MINISCREEN® universal rails, 1 LYSAGHT MINISCREEN® centre rail, 3 LYSAGHT MINISCREEN® infill sheets, 1 lattice, 27 self drilling hex. head screws #10-16x16, 7 Ripple Tek® or RippleZ...

The size of the cantilever is 10% of the adjacent internal span, or 350mm, whichever is the lesser. Please note that the LYSAGHT TOPSPAN® 61 must be one continuous length from internal span to the end of the cantilever.

The main reason for this is the specially engineered shape of the LYSAGHT TOPSPAN® section.

The size of the cantilever is 10% of the adjacent internal span or 500mm whichever is the lesser. Please note that the LYSAGHT TOPSPAN® 120 must be one continuous length from internal span to the end of the cantilever.

LYSAGHT SPANDEK® is a deeper cladding and therefore, has a greater spanning ability and higher water carrying capabilities. However, because it is a deeper cladding, it cannot be sprung curved to the same tight curves as LYSAGHT CUSTOM ORB®....

While steel framing may have higher sound transmission characteristics than that of timber frames there will be no shrinkage or cracking noises due to frame settlement, so steel frames will not be any noisier than any other framing material.

With steel in house frames, this movement is negligible due to minimal direct heat transfer to the frame, even in hot weather. Furthermore, steel possesses a compatible expansion coefficient with that of plasterboard, thereby minimising the incidenc...

No! The move to lighter gauge materials and boxed sections in the frames allows the use of new nailing techniques or cheaper needle point screws. Nailing, or a combination of nails and screws may also be used depending on the application.

Yes. We have fully tested and evaluated our fence systems both in our NATA registered laboratory and using the latest computer modelling software. We can certify that they meet all relevant Australian Standards, including AS1538-1988 (Cold Formed St...

Wall cladding profiles are not as robust as roofing profiles and thus need to be limited in length to minimise the possibility of damage due to handling. Thus the length available in LYSAGHT EASYCLAD® is limited to 9000mm.

No. LYSAGHT® fencing has not been designed or tested for use in this application. It is highly likely the soil will cause corrosion of the COLORBOND® steel.

No. LYSAGHT SHEERLINE® Gutters are usually used on straight runs.  If corners are required the plumber will need to fabricate them.

Yes, LYSAGHT® Gutters offer various fixing methods. You have the choice of fixing to our LYSAGHT NOVALINE® Fascia System using our secret fixed Spring Clip and Overstrap that require no drilling or screwing, or the General Purpose Bracket wh...

LYSAGHT EMLINE® Gutter is the largest of our residential gutters. It is only produced in Queensland due to the heavy rainfall experienced in this state. The front measures 140mm, the base is 125mm and the back is 89mm. It is available with ...

There is a wide range of tapers that are available in LYSAGHT LONGLINE 305®. LYSAGHT LONGLINE 305® has a cover width of 305mm and it can be tapered to a narrow end as low as 145mm (over a minimum sheet length of 5m).

Yes! These materials should be isolated because in the presence of water these materials will develop galvanic cells which will result in rapid destruction of the protective metal coating of the steel frame. Copper pipes are easily isolated from the...

There will always be projects where this will be necessary. In these situations we can provide the traditional purlin profiles (subject to enquiry), however there may be an extended lead-time or some minimum order requirements.

Capping is available for both the LYSAGHT SHEERLINE® and LYSAGHT EMLINE® gutters. Used for barge capping, the profile matches the fascia gutter.

Yes! When installed correctly, steel frames are safe because the frames are earthed. When exposed to a live wire, the earthing will create a short and trip the residual current safety switch reducing the chance of electrocution. All new ho...

LYSAGHT TOPSPAN® 40 is suitable for use in cyconic regions when supplied in 0.75 BMT or greater.

LYSAGHT TRIMWALL® is available in a 0.35mm base metal thickness (BMT). For roofing products we recommended using 0.42mm or 0.48 BMT our roofing equivelent for TRIMWALL® is TRIMDEK®

No, we recommend LYSAGHT CUSTOM ORB®, in 0.42mm or 0.48mm base metal thickness (BMT) for roofing purposes. LYSAGHT CUSTOM BLUE ORB®, 0.6mm BMT can also be used for curved roofing. LYSAGHT WALLCLAD® is available in a 0.55mm base metal thi...

By span we take the distance between centres of supports. There are 3 major considerations when establishing span distance:1. What slab thickness is being used?2. What gauge of LYSAGHT BONDEK® is being used? 3. Is the underside of the slab going to be...

There are clips for both metal and timber fixing. The clips for metal fixing are called metal fix clips, and have the tail of the clip bent in a 'U' shape. These are made to slide over the back edge of standard metal fascia. A clip to suit a timber ...

Yes, these are called internal or external 'mitres'.

Standing and looking toward the house, with the front of the gutter facing you, the left hand side is the left hand stop end and the right hand side is the right hand stop end.

We recommend spacing the clips approximately 1000mm apart, along the gutter.

Yes. though for detailed availability you should refer to your local BlueScope Lysaght branch or distributor. Generally, it is sold as stock lengths of 7500mm.

Generally LYSAGHT TOPSPAN® 40 is sold in stock lengths of 7500mm. Custom cut lengths may be considered for large volume orders. Contact your local BlueScope Lysaght branch for further information.

Most fences feature galvanised steel posts and COLORBOND® steel infill sheets. Immersing the galvanised steel posts in concrete does not cause any corrosion problems but you should not allow the concrete to contact the rails or infill sheets of the...

"LYSAGHT CUSTOM ORB®" is the name given to the "corrugated iron" cladding shape made by BlueScope Lysaght. The name came from the customs stamp on the corrugated iron when it was first imported from England about 150 years ago. The stamp was of ...

Each product has benefits and uses in particular situations. As a cladding LYSAGHT CUSTOM ORB® in a 0.48mm BMT has about the same strength as LYSAGHT CUSTOM BLUE ORB® in 0.60mm. Therefore, if you don't need to curve the material and it ...

The high gloss provides greater light reflectance and this reduces the need for additional lighting or translucent roof sheets. The colours have also been chosen to assist in getting this "lighting" affect. The finish is also aesthetically pleasing ...

The number of downpipes required depends on the design and layout of the gutters. To calculate the capacity you need to refer to our information on how to Install LYSAGHT® Steel Roofing & Walling, "Chapter 6, Roof Drainage". This will give the for...

LYSAGHT SPANDEK® can be sprung curved. The sheets are delivered in straight lengths but curved as they are installed onto the supports, to form a curved roof. See our manual on how to Install LYSAGHT® Steel Roofing & Walling for more...

The LYSAGHT INTEGRITY® profile was made in two versions up until August 2001. These were the LYSAGHT INTEGRITY® 820 (with a cover width of 820mm and a rib height of 48mm) and LYSAGHT INTEGRITY® 890 (with a cover width of 890mm and a rib ...
