Styleline has been specifically designed to produce contrasts of light and shade. Its stylish shape & the way it plays with light reflection means you only see the best from every angle, adding a contemporary look to your building.
All dimensions given are nominal
Sheet width: ±5mm
Sheet width for aluminium +0, -15. If sheet cover widths are critical, advise Dimond at time of order.
Sheet length: +10mm, –0mm. For horizontal wall cladding where notified at time of order of intended use, tighter tolerances can be achieved +3mm, –0mm.
*Please note: only Styleline is suitable for drape curving or crimp curving
**Hi Five only
(1) Recommended maximum purlin spacing at minimum radius
(2) Based on 1.1kN point load support, but not intended for roof access.
n/a – not available
Roll-forming facilities for Styleline at: Auckland, Hamilton, Christchurch, Wellington, Whangarei, Dunedin
Manufacturing location for Duraclad: Auckland
Sheet lengths: Styleline, Hi Five and VeedekTM are 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.
Styleline Limit State Load / Span Capacity
(span in mm, distributed serviceability loads in kPa)
- In any category, spans above the maximum shown should not be used. Category 1 and 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.
- Loads given are based on 4 screw fasteners/sheet/purlin.
- Loads given are limited to a maximum of 4.5 kPa. If design requirements exceed this limit, contact Dimond for specific advice.
– Serviceability Limit State loads are not applicable to the Duraclad material, as it does not experience permanent deformation.
– System must include Safety Mesh if intended for use as a Restricted-Access roof. Refer Section 126.96.36.199 of Technical Manual.
- N/R = not recommended.
- End span capacities given in this table are based on the end span being 2/3 of the internal span.
- Design Criteria for Limit State Capacities
- 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.
- Ultimate Limit State
No pull through of fixings or fastener withdrawal resulting in sheet detachment due to wind up-lift (outward) loads.
- Serviceability Limit State
- System Design
The span capacity of Styleline, Hi Five and VeedekTM are determined from the Styleline, Hi Five and VeedekTM Limit State Load/Span Capacity Chart using the section of the chart appropriate to the 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.
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.
1. Unrestricted-access roof
Expect regular foot traffic to access the roof for maintenance work and able to walk anywhere on the roof. No congregation of foot traffic expected.
2. Restricted-access roof
Expect occasional foot traffic educated to walk only on the purlin lines, in the profile pans, or carefully across two profile ribs.
Walkways installed where regular traffic is expected, and “Restricted Access” signs placed at access points.
3. Non-access roof or wall
Walls or roofs where no foot traffic access is possible or permitted. If necessary, “No Roof Access” signs used.
- 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.
Styleline Fastener Design
Styleline should be screw fixed to either timber or steel purlins. The use of the appropriate length of 12g screw will ensure failure by screw pull out will not occur under loads within the scope of the Limit State Load / Roofing Span Capacity Chart.
*If sarking or insulation is used over the purlins or for wall cladding fixing onto a cavity batten, into the stud, the screw length will need to be increased.
For screw size range and fastener/washer assembly refer Section 188.8.131.52 of Technical Manual.
The Limit State Load / Span Capacity Chart is based on 4 screw fasteners/sheet/purlin without the use of load spreading washers (except for Duraclad material, which must be fitted with profiled metal washers and 36mm EPDM seals).
Profiled metal washers are recommended for use:
- 1. On end spans, or large internal spans where the Ultimate Limit State distributed load is limiting. Contact Dimond for specific advice in these design cases.
- When required to enable the fixing system to accommodate the thermal movement of long sheets – see Section 184.108.40.206 Thermal Movement of Technical Manual.
- Wherever the designer wishes to ensure the risk of fastener over-tightening will not cause dishing of the crest of the
- profile rib.
Use in serviceability categories (1) or (2) can allow the reduction of fasteners to an average of 2 screw fasteners/sheet/purlin. If this is done, the distributed load capacities given in the chart should be reduced using a multiplying factor of 0.5.
Long spans may require the specification and use of side lap stitching screws – see Section 2.3.2C Installation Information: Layout and Fastening of Technical Manual.
Restricted access roof, 0.55mm G550 steel Styleline has a maximum end span of 1500mm and a maximum internal span of 2200mm. The following distributed load capacities apply.
