PURLINS, both C and Z, are available in various sizes rolled to any length. They can be ordered plain or with Holes prepunched, as per standard end punchings (shown below) or punched to any layout required. The standard maximum length for delivery of purlins is 12 metres. Lengths that are greater than 12 metres long are obtainable. However they then require special delivery vehicles, prearranged delivery times and onsite handling capabilities. Pricing Table below.
C PURLINS: C sections have flanges which are equal in size and are commonly used for simple supported spans. C sections are not lapped together, for continuous spans they are end butted.
Z PURLINS: Z sections are made with one flange broader than the other. When one purlin is rotated 1800 two sections can be bolted together enabling them to be lapped. Lapping the purlins over interior supports improves the load capacity and rigidity of the purlins. Z sections purlins can also be used, like C sections, in the application of simple spans.
