Allowable Roof Spans
The allowable roof spans for the TL-5TM roofing profile in Region C are shown in Table TL RS CY 001 and Table TL RS CY 002.
The allowable spans have been determined from tests carried out in accordance with AS4040.0-1992, AS 1170.2-2011 and the NCC (BCA) 2016 Specification B1.2 for the design of buildings in cyclonic areas.
Figure TL CY Local Pressure Factors 002
Note:
The local pressure factors (KL) are shown in Figure TL CY Local Pressure Factors 002 are not applicable at the ridge where the roof pitch is less than 10°. The value of ‘a’ is the minimum of 0.2 breadth, 0.2 width or the height.
Fixing of Cladding
Fasteners must be selected to match the life expectancy of the cladding material. Recommendations from fastener manufacturers should be sought. Only fasteners complying with AS 3566:2002 and those that are compatible with the roofing material should be used for its fastening.
All fasteners used externally should be fitted with an EPDM seal. Do not use punches to form fastener holes. Fasteners are to be fixed at each crest of the TL-5™ roof sheeting.
Insulation
Care needs to be taken when installing insulation with roof sheeting. When insulation thickness up to 50mm are installed the screws detailed in Table TL PF NC 001 may need to be increased depending on the thickness and density of the insulation. When the screw is properly tightened into metal there should be a minimum of three (3) threads protruding past the support being fixed in to. For timber the screw must penetrate the timber as much as the screws detailed in Table TL PF NC 001 do without insulation.
For insulation thicknesses greater than 50mm Fielders® recommend the use of a thermal spacer to help maintain Rw values as well as minimising any bulging in the profile caused by the insulation.
TL-5™ Installation Procedure
For installation procedures see section “Typical Pierce Fix Installation Guide”. For general handling instructions refer to section “Maintenance and Care”
Turning of Roof Sheeting Ends
Refer to section “Flashings, Cappings & Ends of sheets”.
Maximum Sheet Length
See section “Thermal Expansion and Contraction of Steel Sheeting”.
Curving
For details regarding spring fixing and crank curving of TL-5TM sheets, please see section “Curving of Steel Decks”.
