C Section Purlins
C purlins, as the name implies, are formed as in the C alphabet, which is primarily used to support walls and floors. C section purlins or cee section purlins are built to shape a building shell structure’s walls and floor joists, making them also suitable for supporting the beams required for flooring
The maximum distance between purlins is five (5) feet on center. If your building site is in a region that is prone to heavy snow loads or high winds, then we may place your purlins closer together for added strength
Z Purlins
Z purlins or zed purlins are horizontal beams that are designed to form the roof and wall joists of a building shell structure (also view our C section purlins page). They sit between the roofing sheets and the building, acting as a support for the sheet to ensure it is firmly attached and safely in place.
Z-sections are common structural components used for support. These steel struts are typically roll formed because they are used in construction, transportation and manufacturing industries where accurate dimensions are required.
Steeline Z Purlins are made from Colorbond steel and are roll formed to length with holes punched to your specification.
- Z profile sections allow for lapping
- Improved load capacity and rigidity with lapped Z sections
- Option to lap Z Sections in various combinations.
- Available in a range of steel grades
- Spans further
- Factory hole-punch options available
Difference between C and Z Purlins
Z and C purlins have different angles. The C purlin has an angle of 90 degrees, and the Z purlin has an angle that is less than 90 degrees. Due to this, Z purlins are more flexible than C purlins and can be used for a variety of purposes.
Full range of thicknesses available for both Z and C purlins are:
1.2mm 1.3mm
1.4mm 1.5mm
1.6mm 1.8mm
2.0mm 2.5mm
