Design Issues


In the absence of specific product standards, designers have a number of options when specifying purlins.

  • Nominate the purlins by size and specific manufacturer, to the exclusion of all others
  • Specify by size and manufacturer and allow equivalent manufacturers; or
  • Specify the major dimensions and properties such as: depth, flange width, base metal thickness, yield strength, protective coating mass of section and leave the choice of manufacturer to the contractor.

Selection of the correct coating weight, Z350 or Z450, is critical to the long-term corrosion performance of the purlin.

The choice is dependant on the environment in which the purlin is to be used. For example, Z350 will suit most applications that are not subject to high corrosive environments. For high corrosive environments you need to specify Z450.

Please refer to our technical specifications for more details.
