Overview

Heritage Tray™ Performance



Heritage Tray™ markets itself as an elegant, economical and flexible roofing profile. Heritage Tray™ requires no additional plywood substrate thus reducing costs. Additionally, it can be roll formed on site, an attractive logistical option for larger construction projects.

Sheet lengths:
Heritage Tray is custom run to order.


Where long sheets are used, consideration must be given to:

  • Special transportation licences
  • Should be run on-site
  • Site access for special lifting equipment
  • Fixing techniques to accommodate thermal expansion

**NOTE
Photovoltaic laminates (PVL’s) can be installed on to this profile at an additional cost when the cladding is completed and other trade have finished or it can be installed at a later date.
Laminates are 348mm wide and available in 5.910mm and 2.585mm lengths. Lead time of 16 weeks
Laminates cannot be installed on raking sections of roofs

Notes
  1. Category 1 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. Loads given are based on 4 screw fasteners/sheet/purlin.
  2. Loads given are based on 1 clip per purlin, and alternative (second) purlin clipping, i.e. hit 1, miss 1. Clips are required to be fitted to all end and valley purlins, under any situation.
  3. Loads given are limited to a maximum of 4.7kPa. If design requirements exceed this limit, Contact Dimond Roofing for specific advice.N/R = not recommended.
  4. End span capacities given in this table are based on the end span being the same as the internal span.
  5. Design Criteria for Limit State Capacities
    1. Ultimate Limit State
      No pull through of fixings or fasteners withdrawal resulting in sheet detachment due to wind up-lift (outward) loads.
  6. System Design
    The span capacity of Heritage Tray is determined from the Heritage Tray 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 two categories below. It is recommended that to obtain a dependable design strength capacity for the ultimate limit state, a reduction factor of Ø = 0.8 is applied.
    The capacities given do not apply for cyclone wind conditions.

    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.

  7. Wind Pressure Guide
    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.
Fastener Design

Heritage Tray™ Fastener Design



Fasteners that are used to secure Heritage Tray clip 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 clip fasteners must be long enough to pass through the substrate, cavity batten and into the main frame by 30mm for timber and 6mm for steel.

Design


Clip fasteners must be fixed closer together on the periphery edges of all roofs in areas of High to Extra High Wind Zones.

Unlike profiled metal cladding, the point load imposed on a fully supported cladding is supported by the substrate underneath.

Minimum pitch for Eurotray® Double Standing Seam is 5 degrees.

Fastener Layout Options


Fix all clipping - 500mm purlin centres - Very high/Extra High


Alternate clipping - 500mm purlin centres - Low - High Zones
