Corrugated Sheeting
Corrugated sheeting is the traditional and familiar S-Rib profile for roofing and cladding applications. It is the oldest and most commonly used roofing profile because of its easy handling and fixing properties and related strength. The S-rib is derived from sinus curve and offers very strong and structural properties.
Available dimensions Corrugated sheeting is available in standard lengths of 1.8m to 14m. The permissible length tolerance for the standard length range will be -0 +5 mm. Sheets outside these parameters are available on request and may be subject to special pricing arrangements. The maximum height which can be transported is 4.3m. This factor should be considered when bullnoses and curves are designed.
Installation procedure The required number of corrugated sheets can be calculated as follow: Number of sheets for 8.5 Corrugated = Length of building ÷ 0.610 m (Cover width of sheet) Number of sheets for 10.5 Corrugated = Length of building ÷ 0.762 m (Cover width of sheet) Roof sheets and vertical wall cladding (side cladding) must be laid with one and a half corrugation side lap and must be fixed through the crests of alternate flutes to purlins using 50 mm Top Speed or Tex screws into steel purlins and 65 mm Tex or Top Speed screws in the case of timber supports. All fasteners must incorporate 19 mm dia bonded washers. In order to qualify for a guarantee on Zincalume®, Colorbond®, ColorPlus® and ZincAL® sheets the following fasteners supplied by Buildex Industries should be used: Metaltex Climaseal 3 for steel purlins and Timbertex Zacs 4 for timber purlins. The use of these fasteners will dramatically increase the life span of the roof sheeting as corrosion caused by fasteners is avoided. When Corrugated sheeting is double overlapped the covering width for 8.5 Corrugated changes to 535 mm and for 10.5 Corrugated changes to 686 mm.
