Steelbond Roof Installation

About Steelbond

Steelbond Roofing Installation

Steelbond roofing is an engineered designed roofing profile that is suitable where high deformation resistance is required. Steelbond ® is a high tensile steel roofing manufactured from 0.44mm BMT*. Steelbond ® roofing comes in the standard range of Steelbond® colors. Minimum roof pitch is 10°.


Location of Fasteners at Supports

Steelbond ® may be fastened to timber or steel supports by conventional crest fixing. Fixing Spacing’s  should be every 0.900mm and at end and end laps for normal conditions and 0.800mm fixings for severe exposure conditions. Higher wind pressures can be withstood by use of 0.600mm fixings in cyclonic conditions.

Fixing Fastener Location

Ensure all screws are in a perfect line for aesthetics and pride in the installation; this is achieved by running a simple chalk string at screwing points.

Steelbond roofing ® sheets shall be cut in a way so as to avoid damage to the sheets and other nearby finished building products.


Handling of Material

When handling Steelbond ®, extreme care needs to be taken to preserve the quality of the finish. Packs should be kept dry and stored above ground level whilst on site. If the sheets become wet, these need to be separated, wiped and placed in the open air to dry.


Steelbond roof sheeting comes in 5.84 meter long lengths. Steelbond is cut to the required length on site. Steelbond roof sheets need to be site measurements, not those taken off building plans.

The required sheet length is obtained by measuring the distance from the ridges to external edges, or fascia and adding 50mm for overhang into the gutter. Length tolerance on Steelbond ® is ±0-15mm.

Walking on Steelbond®

When walking on Steelbond ® roof sheeting, always wear flat rubber soled shoes and ensure that you walk only over areas where you have installed purl-in or batten supports.


Prior to leaving the work site at the end of the day, ensure that you remove all foreign debris, screws, rivets and especially any swarf from drilling or cutting from the roof surface or from inside the gutters. These systematic cleanups avoid the onset of premature corrosion of the roofing or guttering.

When the job is fully completed remove all the protective film from all tiles and all flashing’s/accessories.

Ensure sure the job site is left clean and tidy.



Never use lead flashing’s with Steelbond ® steel roofing as these products are inert materials. Drainage from copper roofs onto Steelbond ® roofing or rainwater products should not be allowed.

Harsh Environments

If you intend to use Steelbond ® roofing within 1km of industrial, chemical, marine or unusually corrosive environments please contact your nearest Steelbond distributor for advice on the right product.
