Description

Smartspan roofing and walling has a nine-rib design for maximum strength on domestic and industrial cladding projects.

Feature:

• Has a 700mm coverage and the minimum recommended roof pitch is two degrees (1 in 30).S
• Subject to thermal expansion. Darker colours are affected more than light, and spring curved sheeting needs additional consideration.

Spring Curving

• Smartspan may be spring curved using purlins at a maximum spacing of 1200mm for .42mm BMT and 1400mm for .48mm
  BMT. The curve must have a minimum radius of 20m for .42mm and .48mm BMT. The maximum radius is 60m to allow for sufficient drainage over a crest. The side laps must be sealed wherever the roof pitch is less than the recommended minimum.

Available in the standard range of COLORBOND® steel colours and in unpainted ZINCALUME® steel.
