High Quality Purlins
Stratco purlins are crisp, clean and square and by any assessment are a quality product. There is no need to tolerate rounded corners, inaccurate lengths, or out of square purlins any more. Insist on quality Stratco purlins for your project.
Fast Service
Stratco offers an exceptionally fast service. Installation of new state of the art machinery allows not only faster production times, but greater flexibility to meet your needs. A guide to standard lead times can be seen in the table below: For larger projects, some additional time may be required.
Installer Friendly Bridging System
'Rapidfix' bridging is a very fast and easy to install system developed with your installer in mind. The receiver end has a unique locator tag that allows both ends to be held in place. Installation is easier and faster for the rigger who is operating well off the ground, often in windy and difficult conditions. Rapidfix will save both time and money.
Engineering Support
Stratco Engineers have carried out extensive testing on both purlins and girts, and on the 'Rapidfix' bridging system. Capacity tables have been calculated in accordance with limit state design principles and comply with Australian / New Zealand Standard AS/NZ 4600 : 1996 Cold formed steel structures, using software developed by the Centre for Advanced Structural Engineering at the University of Sydney. They are your guarantee of strength and structural sufficiency.
