Secondary framing is an important component of many pre-engineered metal buildings. Purlins are also referred to as ‘secondary structures’. Most commonly known to be lightweight construction elements manufactured from sheet metal strips. These sheets are available in galvanized C & Z sections.

Supplied plain or punched, galvanized purlins are manufactured from high tensile steel for increased strength, reduced weight, and a long serviceable life. QSIF can manufacture a complete range of structural C and Z purlins and girts for industrial buildings, garages, verandahs, and carports, in fact anywhere that strong, reliable steel framing is required. C Purlins: C Purlins are used as Purlins over walls, rafters, floor joists and studs for walls. Z Purlins: This shape helps the Purlins to overlap joint and is stronger and studier than the C purlins. As a result, they tend to be used for large-scale The features are as follows:

  •     Strong structure
  •     Seamless and straight
  •     Choices of customized lengths
  •     Lightweight makes it easy to handle and transport and also reduces the cost up to 40%
  •     The automatic controlled manufacturing ensures close tolerances
  •     Fast and quick to install
  •     Excellent resistance to corrosion
  •     Long-lasting and durable
