CLASSICORR is sinusoidal profile that can be used both as roofing as well as cladding material. With its origin dating back to the Victorian era, it is probably the most commonly used sheeting profile in the world today.
The fact that the corrugated sheeting has been around since the turn of the 20th century, proves the ease with which this S-Rib profile can be effectively used as a roofing and wall cladding option.
|Base Material||Pre-Painted Aluminium Zinc coated steel|
|Overall cover width – mm||864|
|Effective cover width – mm||800|
|No. of troughs||10.5|
|Pitch – mm||76|
|Available Thickness||30G (0.25 mm), & 28G (0.30 mm)|
Recommended minimum timber cross-sectional size are :
Purlins - 75 X 50mm, Trusses - 100 X 50mm.
Maximum Purlin Spacing
0.25mm thickness material :- 600mm.
0.30mm thickness and above :- 800mm to 1mtr.
Note :-It is recommended to use single lengths to cover each run of roof from crest to eave and avoid end lapping for better aesthetics and economy.
When using Classicorr sheeting, the recommended minimum pitch for roofing sheets longer than 15 meters is 15 Degrees; while it is 10 degrees for sheets shorter than 15 meters.
70mm self-drilling timber screws or twisted shank roofing nails are to be fixed through the crest of the profile ribs using an electric screw guns (drill) or by hammering through pre-drilled holes. 65mm self-drilling screws to be used on steel purlins. Either fastener must be used in conjunction with appropriate uPVC washers.
Note:- Classicorr are fixed by drilling fasteners through its crest, its recommended to use minimum 3 fasteners across each width of the profile (both ends at the overlap and center).
