Architectural Specification

The roofing/walling shall be 0.50mm TCT in IMETAL I-DECKTM decking in continuous lengths with trapezoidal ribs 25mm high. Sheeting material shall be protected steel sheet to AZ150 aluminium/zinc alloy coating with infrared baked paint film of selected colour from COLOURCOIL® range.

Colours

The colour and materials specification is available from COLOURCOIL® brochures.

Spans

The spans at minimum 1200mm take account of 'normal' foot traffic and wind resistance including local pressure zone effects. The rib height is 25mm while the effective cover width is 760mm.

Fasteners

All fastening screws must conform to AS3566 - Class 3. They are to be hexagon headed and for roofing must be used with sealing washers. For connecting to purlins or top hats use:

Compatibility

All building products need to be checked for compatibility with adjacent materials. These checks need to be for both direct contact between materials, and where water runs from one material to another. The following guidelines generally avoid material incompatibility:

  • For zinc-aluminium alloy coated steel, avoid copper, lead, green or treated timber, stainless steel and mortar or concrete.

Installation

IMETAL I-DECKTM decking is readily installed with or without fiberglass/rockwool insulation blanket. If practical, lay sheets in the opposite direction to prevailing weather. Installation of IMETAL I-DECKTM decking is a straightforward procedure using the following fixing sequence:

  1. Ensure all purlins are in line and correctly installed and the mesh and blanket (if specified) are in place.
  2. Position and fix the first sheet ensuring the correct sheet overhangs (minimum 50mm). Ensure that screws are not overtightened.
  3. Continue to fix subsequent sheets checking the sheet ends at the lower edge are exactly aligned.

It is important that the underlap of one sheet does not protrude beyond the overlap of the next - if this is unavoidable, the underlap must be trimmed locally or water 'drawback' may occur.

  1. Measure the overall cover width at top and bottom of the sheets from time to time to avoid 'fanning'.
  2. For roof spans exceeding 900mm and wall spans exceeding 1200mm, stitch the sidelaps at midspan.
  3. Turn up the pans at upper roof edge and turn down the pans at the lower edge and install flashings.
  4. Clean up the roof after each days work, removing all screws, cuttings, swarf etc, and leave roof clean and watertight.
