Dimondclad Rib 50 Performance

If versatility is what you are after then Dimondclad is the perfect cladding solution. Dimondclad's clean, efficient lines and well concealed laps are excellent for both exterior and interior cladding. Dimondclad Rib 50 features wide ribs with narrow pans for the opposite look to Dimondclad Rib 20.

Sheet lengths: Dimondclad Rib 50 is custom run to order.


Where long sheets are used consideration must be given to:

  • Special transportation licences for sheet lengths over 25m
  • Site access for special lifting equipment
  • Fixing techniques to accommodate thermal expansion.

Refer Section 2.1.3.4 of the Technical Manual.

Load Spans

Dimondclad Rib 50 Detailed Design



Design Criteria for Limit State Capacities.

  1. Serviceability Limit State
    No deflection or permanent distortion that would cause unacceptable appearance or side lap leakage due to inward or outward wind loads.
  2. Ultimate Limit State
    No pull through of fixings or fastener withdrawal resulting in sheet detachment due to wind up-lift (outward) loads.

System Design


The span capacity of Dimondclad Rib 50 is determined by the serviceability requirement for acceptable appearance and should not exceed 1400mm.

The ultimate wind load should not exceed 3 kPa.

The Dimondclad Rib 50 profile is not intended for use as roofing products, and must not be used in situations where foot traffic point loads can be applied.

Fastener Design

Dimondclad Rib 50 Fastener Design



Dimondclad Rib 50 should be screw fixed over cavity battens to either timber or steel framing where a high level of appearance is required. Nail fixing to timber may be used in an interior situation not exposed to the weather. The use of the appropriate length of 12g screw will ensure failure by fastener pull out will not occur under the load limitation given.

*If sarking or insulation is used over the framing, screw length will need to be increased.

For screw size range and fastener / washer assembly refer Section 2.2.3.1 of Technical Manual.

The Span Capability and Sheet Appearance is based on fasteners at 260mm maximum spacing across the sheet without the use of load spreading washers.

Spans greater than 800mm will require the specification and use of side lap stitching fasteners – see Section 2.3.2C Installation Information: Layout and Fastening of Technical Manual, for fastener type.

As a guide for non-specific design the following S.L.S. design loads in accordance with the MRM Roofing Code of Practice can be used for buildings less than 10m high, otherwise AS/NZS 1170.2 should be used

Low wind zone = 0.68kPa, Medium wind zone = 0.93kPa, High wind zone = 1.32kPa, Very high wind zone = 1.72kPa and Extra high wind zone = 2.09kPa.
