All
PWS profile sheets are manufactured from pre-coated steel. Throughout
the manufacturing process great care is taken in the production,
handling and storage prior to despatch.
To
ensure that you get the best possible results from your PWS profiles,
equal care and attention must be provided on-site in handling and
storage.
This
page is intended as a guide to main problem areas, which can result
in damage or deterioration.
Illustrated
you will find a variety of the most common on-site problems associated
with steel roof and wall cladding.
Inevitably the finished structure is a reflection of how effective
the on-site care and handling has been. Scratched or scuffed profiles,
damaged corners, distorted panels and corrosion can all be avoided.
All it takes is to follow basic good housekeeping principals, several
of which are illustrated. We recommend that, as with all roof profiles,
mastic sealant or tape be applied to all side laps and in particularly
exposed environments that side laps be stitched or riveted
1.
HANDLNG Always remove the top sheet from the pile by turning sideways.
Never drag the top sheet off the stack
2.
LIFTING Panels should, where possible be lifted into position by
hand avoiding damage to edges or corners If it is necessary to use
a hoist, ensure that the rope (rather than chain) does not distort
the panel
3.
DRILLING Fixing holes should be drilled and all swarf removed, swarf
can seriously damage the roof coating
4.
STORAGE Never leave profile stacks uncovered and exposed to the
elements Always ensure that stacks are under cc~er but with adequate
ventilation, and if possible on a raised sloping platform, to allow
water to drain off
5.
DAMAGE PREVENTION Avoid storing panels where they will receive accidental
damage to corners etc, or where people will walk across them
6.
CUTTING Never cut the sheet panels without adequate support, this
may distort the panel. All longitudinal cuts should be made with
snips, a reciprocating power saw or nibbler should be used for other
site cutting. Cut or exposed edges should be kept to a minimum and
covered by laps or flashings
