Gravity IBR Roofing & Building Supplies Manufacturers and Supplies Corrugated Metal Roofing Sheets combine high-quality steel with a corrugated design to provide incredible strength.
This makes them ideal for both Commercial and Agricultural Buildings, such as Warehouses, Barns, and Stables. They are also lightweight when compared to many other roofing systems, making them suitable for many residential projects. These include garage roof replacements, shed roofs and more.
Gravity Building Supplies & Hardware manufactures and stocks IBR and Qtile Corrugated steel Roofing Sheets in a variety of thicknesses and lengths. This allows you to find the perfect size for your project, maximising coverage whilst minimising wastage.

These materials are made from thin steel sheets (typically less than 1 mm thick) and are coated in either Zinc (Galvanised Iron), Aluminium, Zinc, Magnesium Alloy (Zincalume) or paint over zinc alloy (Colorbond) coating.
There is also a stainless steel-based version of Colorbond for extreme coastal environments.
Steel sheet materials come in a wide range of profiles (the shape, corrugated or otherwise, when viewed end-on), including the common Corrugated Iron, the Mini version (such as Lysaght Mini Orb, which is usually used on walls but can be used as a roofing material), as well as profiles more commonly used for commercial roofing although also suitable for some domestic projects, such as Trimdek, Klip-Lok and numerous others.
Sheet steel products are all used in a similar manner: They are either screwed (or sometimes nailed) to wood or steel battens, or they are clipped onto concealed brackets that are screwed to the battens.

Both methods have the edges of the sheets overlapping to prevent water ingress but concealed fixing systems eliminate piercing of the sheets associated with screw or nail fastening and provide a more reliable weather seal. Ridges are finished with purpose-made capping and, typically, various designs of gutter complete the eaves’ detailing to provide a neat and clean finish to the roof.
Another technique that uses sheet roofing is the ‘standing seam’ method. Sheet metal ‘trays’ are formed from flat sheets with folded vertical edge seams that interlock and are then crimped down to complete the seam. This allows for very long tray panels to be used (up to 10 metres long) and is suitable for larger roofs and roofs with concave or convex curves. The disadvantage of the system is that once panels are locked together, they are harder to separate compared to sheets that are simply screwed down.
The advantages of sheet steel products are considerable. They are light and relatively easy to handle, easy to fasten and quick to install (for professionals, at least), are very strong and, if installed correctly, will last for decades with minimal maintenance.

They are also extremely fire resistant, although heat and sound travel through sheet steel products with ease.
Sheet products have very few disadvantages, but poorly installed sheeting can become a sharp hazard when cleaning gutters if the sheets extend too far into the gutter.
Many sheet steel products contain recycled steel (check datasheets for recycled content and other sustainability features, as it varies between products and manufacturers), and all sheet steel is easily recycled through well-established recycling systems, so there is no reason for these products to end up in landfill at the end of their useful life.
