Hiland Tray

Overview

Roll formed onsite with a mobile roll forming facility, Hiland Tray is an innovative product that is available in long, single lengths. Hiland Tray is snap-locked to concealed fixings via a simple clip system that is attached to the roof and wall purlins.

Versatile and Innovative Cladding

Roll formed onsite and snap-locked to concealed fixings

Mobile roll forming allows Hiland Tray to be manufactured onsite in both urban areas and remote alpine regions. It delivers a clean, high quality product with reduced handling time.

Featuring an attractive design that is available with swages (ribs) within the pan, or no swages for a clean, flat profile. Regardless of the options chosen, the flat nature of the tray means that some panning/rippling can be evident which adds to the crafted and characteristic appearance of the product.

The completed finish is smooth and uncluttered due to Hiland Tray’s innovative concealed fixing system. Hiland Tray snap-locks to a simple clip that is fixed to the roof and wall purlins.

Available Colours:

  • Bluff
  • Castle
  • Knight
  • Loch

Brochure Selection Use & Maintenance

High Performance Cladding

The Hiland Tray profile has a high rib height of 44mm that enhances its smooth bold lines and provides greater water carrying capacity and strength for snow loading applications in alpine regions. Hiland Tray is available in 0.55mm BMT zinc/al and in a range of contemporary pre-painted colour steel options to suit any colour pallet.

Maintenance

The performance of Hiland Tray roofing and walling over time depends on its correct application and maintenance. Maintenance should be performed as often as is required to remove any dirt, salt and pollutants.

Where Hiland Tray cladding is used in severly corrosive environments, cleaning should be performed more often. It is important that screws have the same life expectancy as the Hiland Tray cladding you have specified. Packs of Hiland sheeting should always be kept dry and stored above ground level on site. If the sheets have become wet, they should be separated, wiped and placed in the open to dry.

Refer to the Stratco 'Selection, Use and Maintenance' brochure for more detailed information about the correct use and maintenance of this product.

Engineering

Testing Systems

Stratco have developed purpose built testing equipment for the testing of cladding systems sufficient to ensure the structural adequacy of the product it produces.

Compliance

Wind Capacity Tables are based on testing for compliance with the New Zealand Metal Roof and Wall Cladding Code of Practice. Span tables have been developed by determining relevent wind pressures in accordance with AS/NZS 1170.2. Capacity tables are in limit state format.

Spans

Span tables are based on a maximum overall building height of ten metres and a 500 year design return period for strength limit state wind load assessment. Roofing spans specified are suitable for snow loading up to 2kPa in accordance with the New Zealand Metal Roof and Wall Cladding Code of Practice.

Roofing calculations are based on Cpe=-0.9 and Cpi=0.2, walling is based on Cpe=-0.65 and Cpi=0.2. Local pressures are as specified and have been considered for both strength and serviceability limit states. Roof spans take into consideration loads incidental to maintenance noting ends spans allow for foot traffic over supports only.

All pressures have been determined assuming wind loading in any direction without shielding but which is not affected by topography (i.e. Mt=1.0). Allocated spans do not allow for Lee Zones, for areas within these zones, utilise the wind capacity tables to calculate spans based on the relevant allowance for Lee Multipliers.

Additional engineering advice can be obtained from Stratco if any design parameters vary from those indicated above.

Design Considerations

Hiland Roofing and Walling has a 455mm cover with a 0.55mm BMT material thickness. The minimum allowable roof pitch is 3°.

Fixing Recommendations

Hiland Tray sheets should be laid into the prevailing wind and clip neatly onto the preceding roof sheet. The Hiland Tray clips should be fixed within the recommended support spacings.

Due to the seam height, flashing turn downs into the pan of Hiland Tray sheeting should always be notched around the rib to provide maximum weather tightness.

Fixing to Timber

Two 10 x 30mm wafer-head timber fixing screws (square drive recommended) per clip. Clips located at every sheet overlap and sheet edges at each timber support. Timber supports to be 100 x 50mm planer gauged and minimum MGP10 or F5 grade.

Walking on Hiland Tray

When walking on Hiland Tray roofing, walk over the purlins to avoid damage to the sheeting. Wear flat rubber soled shoes and walk flat footed in the pans only. Walking on end spans is restricted explicitly to over the end span purlins with no access allowed directly on end spans due to potential sheet damage.
