Fixing Procedure

Lengths & Roof Pitch

When using Box Profile sheeting the recommended minimum pitch
for roof slopes in excess of 15m is 10º and for slopes less than 15m
is 7.5º. Box Profile sheeting is offered to the mass market in lower
gauges of 0.25 & 0.32m [30 & 28G] and corresponding standard
lengths of 2.0, 2.5 & 3.0. It can also be ordered in special lengths,
subject to transport limitations, up to 9 metres [min 0.4mm thickness) or lower thickness up to 6m (maximum lengths).

Purlin Spacings

Purlin Spacings are dependent on both downward loading and
negative suction loading caused by wind. Your engineer should
be consulted to calculate your load [kN/m²] for your particular
application.

Fastening

Box Profile is pierce-fixed to timber or steel supports. This
means that fastener screws pass through the sheeting. You
can place screws for Box Profile through the crests or in the valleys.
To maximize water tightness, always place roof screws through the
crest. For walling, you may use either crest or valley fixing. Always
drive the screws perpendicular to the sheeting, and in the centre of
the corrugation or rib.

Don’t place fasteners less than 25mm from the ends of sheets The edge of Box Profile with the anti-capillary groove is always the under-lap. it is generally considered good practice to use fasteners alongside lap however, when cladding is supported as indicated in purlin spacings, side-lap fasteners are not usually needed for strength.End-laps are not usually necessary because Maxcover is available in long lengths. When Box profile is laid on slopes of 7.5 degrees or more, cut back the corner of the under sheet, at the downhill end of the sheet to block capillary action
