FLUTELINE
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.
The general shape and appearance of the trapezoidal flutes ensures that Fluteline® is totally acceptable for use as roof and as wall cladding. The deep and broad flutes of the Fluteline® sheeting ensure excellent drainage characteristics, which makes it an ideal sheet for roofing applications. Fluteline® offers optimum strength-to-weight performance and is designed to provide the most advantageous load/span characteristics of our trapezoidal profiles. Fluteline® can be factory cranked, curved and bullnosed to a wide range of radii. For further details contact our Technical Department.
SAMPLE SPECIFICATION
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.
MATERIAL OPTIONS
NOTE 1
When ordering Fluteline ensure you advise Safintra as to whether the end use is as roofing or cladding.
NOTE 2
When installing Fluteline® as side cladding, it is advisable to orientate sheets in a single direction, as this may have a visual impact when reflected in direct sunlight. The direction of the “dot matrix” branding that appears at regular intervals on the backing coat, can be used as a practical guide on site for roofing crews.
NOTE 3
Fluteline® is not rolled with stiffener ribs.
NOTE 4
During installation, clean the roof daily by removing all swarf, pop rivets and unused fasteners or any other debris.
NOTE 5
Safintra recommends the use of Fixtite™ fasteners. Refer to Corrosion Class table under Fixtite™ Fasteners.
NOTE 6
All sheets are to be tanked or turned up at the ridge side of the sheet and are to be lipped or turned down at the eave end.
PURLIN SPACING
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.
LENGTH AND ROOF PITCH
*Refer to the Safintra Technical Department for more information or raise any enquiries in writing to info.safintrasa@safalgroup.com
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 ±5mm is permissible. This applies to straight sheet lengths only.
Note 7
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.
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 centre of the rib. It is recommended that side laps be stitched at 500mm centres.
It’s further recommended that every rib is fixed at the eaves, ridges and the apex of the roof. Side and end laps are to be sealed (in accordance with SANS10400-L:2020) using a suitable butyl product or neutral cure Silicone. Refer to the Fixtite™ fastener webpage for fixing guidelines.
