Sheet lengths:
Solar-Rib® 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


OIL CANNING: Oil Canning is the visible waviness in the flat areas of metal roofing and walling. Oil canning produces an aesthetic effect inherent in standing seam tray profiles and profiles/flashings with wide flat elements. It does not cause detriment to product performance.
Oil canning can occur during the forming and installation processes and during thermal expansion of the roof sheeting during its life cycle. The effect can be more or less pronounced depending on differing light and sun angle conditions and the coating gloss levels.

For Solar-Rib, oil canning can be reduced by the use of vented roof underlay (e.g. Tyvek Metal) and/or the use of backer rods under the tray. There are several options to reduce the oil canning effect in tray type profiles and flashings, for example, a) increasing the thickness of the material, b) using stiffening swages in wide flat elements and c) limiting flat elements to less than 150mm width. For further information, please refer to the New Zealand Metal Roof and Wall Cladding Code of Practice, Section 12.3.

Notes
  1. In any category, spans above the maximum shown should not be used. Category 2 maximum spans are based on static point load testing as a guide, and further limited by practical experience of roof performance under dynamic foot traffic loads. Category 3 maximum spans are limited as a guide to achieving satisfactory appearance for wall cladding.
  2. Loads given are based on 2 screw fasteners/sheet/purlin (x) = one stitching screw between mid-span purlins, (y) = two stitching screws per mid-span purlin.
  3. Loads given are limited to a maximum of 2.5kPa. If design requirements exceed this limit, Contact Dimond Roofing for specific advice.
  4. N/R = not recommended
  5. End span capacities given in this table are based on the end span being 2/3 of the internal span.
  6. Design Criteria for Limit State Capacities
    1. Serviceability Limit State
      No Deflection or permanent distortion that would cause unacceptable appearance, side lap leakage or water ponding, due to foot traffic point loads, inward or outward wind loads or snow loads.
    2. Ultimate Limit State
      No pull through of fixings or fasteners withdrawal resulting in sheet detachment due to wind up-lift (outward) loads.
  7. System Design
    The span capacity of Solar-Rib® is determined from the Solar-Rib® Limit State Load/Capacity Chart using the section of the chart appropriate to grade and type of material, and to the category of serviceability selected from the three categories below. Serviceability loads have been derived by test to the NZMRM testing procedures. To obtain an ultimate limit state load we recommend factoring the serviceability load up by 1.4 in-line with NZMRM guidelines. The capacities given do not apply for cyclone wind conditions.

  8. Serviceability Requirements
    While these categories are given for design guidance to meet the serviceability limit state criteria, foot traffic point load damage may still occur if there is careless placement of these point loads.

    Unrestricted-access roof

    Expected regular foot traffic to access the roof for maintenance work and able to walk anywhere on the roof. No congregation of foot traffic expected.
    Restricted-access roof

    Expect occasional foot traffic educated to walk only on the purlin lines, in the profile pan. Walkways installed where regular traffic is expected, and “Restricted Access” signs placed at access point.
    Non-access roof or wall

    Walls or roofs where no foot traffic access is possible or permitted. If necessary, “No Roof Access” signs used.

  9. Wind Pressure Guide
    As a guide for no-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.
Fastener Design

Solar-Rib® Fastener Design



Fasteners that are used to secure Solar-Rib® down as a roof cladding must penetrate into the purlin a minimum of 30mm for timber and 6mm for steel purlins. For wall cladding the fasteners must be long enough to pass through the substrate, cavity batten and into the solid framing by 30mm for timber and 6mm for steel.

1. A 30mm bonded (BRA) washer may be used in low and medium wind zones and when the sheet length is less than 7m.

Periphery and valley lines must still have a load spreading washers used.

2. When using bonded washers remove the neo from the fastener prior to installing.

3. When using Load Spreading Washers a 12mm (clearance) hole is to be drilled for the 36mm diameter EPDM seal.

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


The Limited State Load/Span Capacity Chart is on 2 screw fasteners/sheet/purlin with the use of load spreading washer


Long spans may require specification and use of side lap stitching screws – Section 2.3.2 C Installation Information: Layout and Fastenings of Technical Manual.
