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.

SAMPLE SPECIFICATION

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.

NOTE 1
Fluteline® is not rolled with stiffener ribs.

MATERIAL OPTIONS

NOTE 4
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 SPACING

Purlin Spacing’s 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
Fluteline® 7 sheeting can be ordered in any length, subject to transport limitations, up to 13,2m. Longer lengths require special transport arrangements. When using Fluteline® 7 sheeting the recommended minimum pitch for roof slopes in excess of 15m is 7.5° and for slopes less than 15m is 5°.

Dimensional tolerances

A length variation range of +10mm or -0mm, and a width tolerance of ±7.5mm is permissible. This applies to straight sheet lengths only.

FIXING GUIDE
Fluteline® is pierce fixed to timber or steel supports. This means that fastener screws pass through the sheeting. Always drive the fasteners perpendicular to the sheeting, and in the center of the rib.
It is recommended that side laps be stitched at 500mm centers. Its further recommended that every rib is fixed at the eaves, ridges and the apex of the roof.
Side laps to be sealed using a suitable butyl product or neutral cure silicone.
Refer to the Fixtite™ Fastener section for fixing guidelines.
