CLASSICORR CORRUGATED
The corrugated profile is sinusoidal and can be used as both roofing and cladding material. With its origins dating back to the Victorian era, it is probably the most commonly known sheeting profile used in the world today. The fact that the corrugated profiled sheeting has been around since before the turn of the century proves that this easy to use and effective profile for roofing and wall cladding is here to stay. Corrugated sheets can be factory cranked, curved and bullnosed to a wide range of radii. For further details contact our Technical Department.
SAMPLE SPECIFICATION
Safintra 0.50mm thick, AZ 150 Zincal® Classicorr® corrugated roof sheeting, crest-fixed to intermediate timber purlins at 1200mm centres and ridge and eave purlins at 900mm centres, with #12 x 65mm Fixtite™ timber fasteners or Safintra approved hex head self-drilling fasteners. Sheets to be fixed with three fasteners per sheet on intermediate purlins and five fasteners per sheet on ridge and eave purlins.
The sheeting shall be Classicorr® corrugated as manufactured by Safintra.
The profile shall be roll-formed with 10.5 sinusoidal crests at 76mm centres, with an effective cover width of 762mm. The crest height shall be 17.5mm and shall be fixed in accordance with the manufacturer’s recommendations.
MATERIAL OPTIONS
NOTE 1
When installing Classicorr® 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 2
During installation, clean the roof daily by removing all swarf, pop rivets and unused fasteners or any other debris.
NOTE 3
Safintra recommends the use of Fixtite™ fasteners. Refer to Corrosion Class table under Fixtite™ Fasteners.
PURLIN SPACING
LENGTHS AND ROOF PITCH
A length variation range of +10mm or -0mm, and a width tolerance of ±5mm is permissible. This applies to straight sheet lengths only.
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.
