Concealed Fix Profiles
We manufacture the following concealed fix profiles: Diamondek, Snap Lock, Nail Strip and Soffit Panel.
In concealed fix systems, the clips and fixings are covered by the roof panels. Therefore, the clips are not exposed to weather. This reduces incidence of rust and reduces the probability of leaks which occur around external fixing points, such nails or screws.
These profiles are available in Clean COLORBOND, Clean COLORBOND ULTRA, Zincalume, Zincal, ColorPlus and ColorPlus Ultima.
DIAMONDEK
DIAMONDEK is the established brand leader in the secret fix market. The profile has been in the market for over 20 years and has been tried and tested on a multitude of designs and application.
DIAMONDEK is a modern, high-tech, aesthetically pleasing profile, suitable for residential homes as well as industrial or commercial buildings.
DIAMONDEK roofing will perform at very low pitches. A minimum of 1.5 degrees is recommended to achieve maximum performance.
Example: Roof width = 6.00m and run-off = 6.30m: 6 + 0.407 = 6.407.
This means 6 sheets of length 6.30m are required.

Snaplock 38.1 mm
Suitable for roof pitches of 1.5 degrees or greater and purlin spacings of up to 1 metre. This profile is very popular in residential applications owing to its aesthetically pleasing finish, as well as the speed and simplicity of fixing.
Seamlock 38 mm
Suitable for the same applications as Snaplock. The side lap of the roof sheet is seamed over together with the fixing clip and the adjacent sheet forming an extremely stable and wind resistant roof covering, which cannot be unclipped. This is also the only concealed fix roofing system that can be smooth-curved, without deforming the sheet through cranking, thereby providing a smooth curved sheet (minimum 0.8 metre radius)
Seamlock 50 mm
Suited to commercial and industrial applications with purlin spacings of up to 1.5 metres.
Nail Strip
Suitable for roof pitches greater than 12 degrees. This is a clipless concealed-fix system and is well suited to the DIY market due to the ease of fixing.
Soffit Panels 22.2 mm
Soffit Panels are well suited to vertical (wall) cladding and for decorative purposes or internal applications, especially in commercial buildings and to a lesser degree in industrial applications.
