Steel Sections

Ortech Steel Sections

Keeping pace with the demands of an ever expanding building industry, Ortech Industries has available a wide range of high quality galvanised steel sections used extensively to support the many Ortech Roof and Ceiling systems.

Versatile in application, Durra Steel Sections are available according to span and general project requirements and are suited to level, curved or raking roof designs. In addition to the complete roof and ceiling systems, the sections are suited for use in suspended ceiling systems, and for particular applications as purlins or girts. Durra Steel Sections have been incorporated by leading architects, engineers and designers into all types of building projects — large and small in all States of Australia and around the world.





All Durra steel sections are manufactured from high quality galvanised steel strip with a zinc coating of Z275 gm/m2. This coating ensures adequate protection from normal atmospheric conditions.


Durra steel sections are designed to support Durra ceiling and roof-ceiling systems in accordance with the relevant Australian Standards. (Refer Span Design Data).


Dimensions and sectional properties of individual sections are shown on the relevant reference sheets in this section.




 On-site cutting of sections, if required, is easily achieved using a power saw with cutting disc attachment, or with a hack saw on smaller sections.


 Durra steel sections, because they are galvanised, may be left on site exposed to weather providing normal precautions for galvanised materials are observed.


 Durra steel sections are custom cut to suit project requirements. Orders should state clearly — the section size, length, hole punching for cleated connections, tee unit location, wedge slot height, the number required of each length, together with clear pick-up/delivery instructions.


 Durra Steel Sections can be supplied with a high-quality powder-coat finish to the exposed are of the bottom tee flange. Contact Ortech Industries for lead time and colour availability. The zinc coated surface of the steel section can be easily and satisfactorily painted providing the technique used is compatible with the zinc surface. Recommended steps are as follows:

– Clean and remove all oil and grease

– Apply one coat of etch primer and undercoat

– Use proprietary brand paint for the final coat
