Description:
Widespan is a roofing and cladding profile designed to provide an economic alternative to deeper Box
Rib profiles without losing the aesthetic appeal of a square fluted profile. The trapezoidal Widespan
profile offers greater covering. Widespan roof sheets are available in a wide range of materials
displaying various structural properties. It should be noted that the load span characteristics are only
to be used as a broad guideline as purlin spacing is also dependent on other factors such as the
prevailing winds in a certain area, snow during winter periods, the presence of dust and other
particles in industrial areas, the type of structure that is being erected etc. We therefore recommend
that an engineer is consulted to determine the purlin spacing for a specific application. Widespan can
be factory cranked, curved and bullnosed to various radii depending on customer's requirements.
Available dimensions:
Sheets outside these parameters are available on request and might be subject to special pricing
arrangements. The maximum height which can be transported is 4.3 metres. This factor should be
taken into account when bullnoses and curves are designed.
Roof pitch:
When using Widespan, the recommended minimum pitch for roof slopes in excess of 30 m is 10.0º and
for slopes less than 30 m is 7.5º. When Widespan roof sheets are end lapped the roof pitch should be
taken into account. The minimum end laps for roofs pitches in excess of 15º is 150 mm and for other
roofs a minimum of 250 mm is recommended. End laps for side sheeting should be at least 100 mm.
It is recommended that end and side laps on low pitched roofs are sealed to ensure watertightness.
Installation procedure:
The required number of Widespan sheets can be calculated as follows:
Number of sheets = Length of building + gable end overhangs - 50 mm / 0.762 m (Cover width of sheet)
Roof sheets must be laid with one corrugation side lap with the narrow flute uppermost and shall be
fixed through the crests of alternate flutes to purlins using 57 mm Top Speed or Tex screws into steel
purlins and 90 mm Tex or Top speed screws in the case of timber roofs, all fasteners shall incorporate
19 mm dia bonded washers.
For vertical wall cladding (side cladding) it is recommended that the broad fluted are fixed externally
with the main and side lap fasteners in the web of the flutes. Side cladding can be fixed using 25 mm
Tex or Top speed screws, all fasteners shall incorporate 19 mm dia bonded washers.
