Packing, Storage and Handling
: Keep the product dry and clear
off the ground on wooden blocks. Do not
slide the sheet over rough surface. If sheets
are wet, wipe with clean cloth. Roofing
& Cladding sheets should be erected
as soon as possible on arrival at the job
site. In case of temporary storage, the
same should be stored in-doors. In case
of outdoor storage, the sheets have to be
covered with tarpaulin.
Walking on roof
: Walk on the valley of the roof thus
keeping your weight evenly distributed.
For cutting the sheets,
the usage of knibbler is recommended. The
cut materials and metal particles are required
to be swept from the ground. Failure to
do so will lead to rusting or surface staining.
Fixing of SDS screws
recommended with Torque adjustable guns.
For roof work, fix screws on the crest.
For wall cladding, fix on the crest or on
the valley. Fasteners to confirm to AS 3566
Class 3 - 4 for external application.
