Dimond Corrugate
Description

Corrugate’s wide sheet cover, rapid fixing and low material cost make it an economical choice of roof and wall cladding material.  It lends its graceful appearance and economy of fixing to almost any type of building structure. 

Key Features
  • Cover: 762mm 
  • Sheet width: 851mm
Scope of Use
  • Minimum Pitch: 8° (approx 1:7)

Dimond long run metal roofing and cladding is intended for use in constructing the building envelope for commercial buildings and residential buildings subject to the limitations listed below.

Attention to the following details is required to ensure the expected system performance is achieved:

  • The selection of the type and grade of sheeting material and fasteners must be based on the life expectancy required and the severity of the external and internal environments.
  • Correct choice of breather type or vapour barrier underlay to suit the building environment.
  • Site storage that keeps product dry and protected from damage.
  • Sheeting handling that prevents surface damage.
  • Avoidance of excessive spans or insufficient fasteners for the expected loads.
  • Correct placement and flashing of penetrations through the roof.
  • Correct layout and installation of the sheeting, underlay and netting.
  • Allowance for thermal expansion and contraction.
  • Sufficient roof pitch to permit complete surface water drainage.
  • Control of allowable contact with dissimilar materials.
  • Awareness and implementation of maintenance requirements, particularly for surfaces not washed by natural rainfall.
  • Correct choice of material for collection of drinking water from a Zincalume or colour finished roof is required.
Limitations on Use

If the need arises to use Dimond long run roofing & cladding outside the limitations and procedures given in the Performance Statements or other referenced literature, or if any doubt exists on product handling or use, written approval for use must be obtained from Dimond before the project commences.
