Zee and Cee Purlins
Mild Steel Purlins
Metaroof Cee sections may be used in single spans, and unlapped continuous spans in multi-bay building and are ideal as eave purlins or where compact sections are required for detailing. Metaroof Zed sections may be used over single spans, unlapped and lapped continuous spans in multi-bay buildings. Lapped continuous spans result in considerable capacity increase in the system.
Zee and Cee purlins are the modern alternatives for conventional MS channels/angles, used as secondary members in industrial sheds for fixing Roofing and cladding sheets. They bear high strength to weight ratio. They are cold rolled from steel sheet of 550mpa tensile strength. The advantage of using these purlins is a variety of depth and thickness option which gives the designer the required freedom to design the most economical purlin. They are available in customised length and thickness with pre-punched holes. With the use of C/Z purlin, one can save up to 40% of steel to be used in construction as compared to the conventional system of using Hot rolled purlin or Hot rolled channels, angles or tubes which have low strength to weight ratio. Purlins section weight is 30-40% less as compared to hot rolled structures.
