Applications:
Widespan is ideal for residential, commercial and industrial roofing applications. Its excellent strength in spanning and fast erection time makes Widespan economical from a structural and erection point of view.
The narrow pans of pierced fix profiles are resilient against oil canning and is thus recommended for any application where aesthetics is a consideration.
Roof Pitch:
The rib height of Widespan enables this roofing system to perform safely at a minimum roof pitch (or roof slope) of 10° for sheets longer than 30m. If the roof sheets are shorter than 30m the roof pitch can go down to 7.5°. 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 15° is 150 mm and for lower roof pitches a minimum of 250 mm is advisable. 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 water tightness.
