Fluteline® is an angular trapezoidal fluted profile sheet with similar characteristics to IBR but having an effective cover of 889mm, which is wider than IBR.
Safintra 0.5mm thick, 889mm cover Fluteline® profiled Zincal® AZ150 Roof Sheeting, fixed to intermediate steel purlins at 2500mm centres and eaves and ridge purlins at 2200mm centres, using 12 x 65mm Metalfix self-tapping fasteners with a bonded washer. Side laps to be secured using #14 x 22mm Metalfix stitching fasteners with a bonded washer over purlins and at centres not exceeding 500mm with #14 x 22mm Metalfix stitching fasteners between purlins. All in accordance with the manufacturer’s recommendations.
The sheeting shall be Fluteline® profile as manufactured by Safintra Roofing. The profile shall be roll-formed with 8 trapezoidal ribs at 127mm centres with a nett cover of 889mm. The rib height shall be 38mm and shall be fixed in accordance with the manufacturer’s recommendations.
Fluteline® is not rolled with stiffener ribs.
Note that when using Aluminium material on galvanized steel purlins, the use of an isolation tape or similar to prevent the bridging of the two dissimilar materials is recommended. Should the two metals have direct contact it will ultimately result in the manifestation of bimetallic corrosion, and the service life of the aluminium will be compromised.
Material and coating thickness can vary regionally. Consult your local Safintra branch for availability.
Purlin Spacings are dependent on both downward loading and negative suction loading caused by wind. An engineer should be consulted to calculate the load (kN/m2) for your particular application.
*0.80 Aluminium-Zinc Material is rolled in G275.
LENGTH AND ROOF PITCH
A length variation range of +10mm or -0mm, and a width tolerance of ±7.5mm is permissible. This applies to straight sheet lengths only.

Cover Width for Fluteline® 7 is 889mm (March 2021 Updates)
During installation, clean the roof daily by removing all swarf, pop rivets and unused fasteners or any other debris.
