Load Span Tables

The allowable spans have been determined from tests carried out in accordance with the following Australian Standards (wind load available by region): AS 1562.1 :1992, “Design and installation of sheet roof and wall cladding - Metal” and AS 4040:1992, “Methods of testing sheet roof and wall cladding”.

Wind Pressure Capacities

TL-5™ cladding offers the full benefits of the latest methods for modelling wind pressures. The wind pressure capacity table is determined by full scale tests conducted at Fielders' NATA-registered testing laboratory, using the direct pressure-testing rig.

Testing was conducted in accordance with AS 1562.1:1992 Design and installation of sheet roof and wall cladding— Metal, and AS 4040.2:2002 Resistance to Wind Pressure for Non-cyclonic Regions.

The pressure capacities for serviceability are based on a deflection limit of (span/120) + (maximum fastener pitch/30).

The pressure capacities for strength have been determined by testing the cladding to failure (ultimate capacity). These pressures are applicable when the cladding is fixed to a minimum of 1.0mm, G550 steel. For material less than 1.0mm thick, please contact your local Fielders representative.

 

Figure TL NC 002 End Spans, Internal Spans and Overhangs illustrates the terminology end spans, internal spans, and overhangs and their reference to the supporting substructure. This terminology has been used in the following Maximum Recommended Span and Wind Load Capacity tables. Long lengths and a special anti-capillary groove in the side-lap allows you to use TL-5 cladding on roof pitches as low as 2° (1 in 30).

Table TL FS NC 001

Note:
1. Do not use punches to form fastener holes. AQUABLOK™ System

The maximum recommended support spacings are based on testing in accordance with AS 1562.1:1992, AS 4040.1:1992 and AS 4040.2:1992. 

Roof spans consider both resistance to wind pressure and light roof traffic (traffic arising from incidental maintenance). Wall spans consider resistance to wind pressure only. 

The pressure considered is based on buildings up to 10m high in Region B, Terrain Category 3, Ms=0.85, Mi=1.0, Mt=1.0 with the following assumptions made: ROOFS: Cpi=+0.20, Cpe=-0.90, Kl=2.0 for single + end spans, Kl=1.5 for internal spans. WALLS: Cpi=+0.20, Cpe=-0.65, Kl=2.0 for single spans, Kl=1.5 for internal spans. These spacings may vary by serviceability and strength limit states for particular projects. 

Fastening Sheets to Supports

TL-5™ profile is pierce-fixed to timber or steel supports. This means that fastener screws pass through the sheeting. 

You can place screws for TL-5™ cladding through the crests or in the pans. To maximise watertightness, always place roof screws through the crests. 

For walling, you may use either crest or pan-fixing. 

Always drive the screws perpendicular to the sheeting, and in the centre of the corrugation or rib. Don’t place fasteners less than 25mm from the ends of sheets. 

Side Lap Fastening

The edge of TL-5TM cladding with the anti-capillary groove is always the underlap (see figures below). It is generally considered good practice to use fasteners along side-laps however, when cladding is supported as indicated in maximum support spacings, side-lap fasteners are not usually needed for strength. 

End Laps

End-laps are not usually necessary because TL-5TM cladding is available in long lengths. If you want end-laps, seek advice from your local Fielders representative on the sequence of laying and the amount of overlap. 

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

It is usual to allow roof sheets to overlap into gutters by about 50mm. If the roof pitch is less than 25° or extreme weather is expected, the pans of sheets should be turned-down at lower ends, and turned-up at upper ends by about 80°. Refer to section “Flashings, Cappings & Ends of sheets”.

Sheet-Ends on Low Slopes

When TL-5™ cladding is laid on slopes of 5° or less, cut back the corner of the under-sheet, at the downhill end of the sheet, to block capillary action. 

Curving

For details regarding spring fixing and crank curving of TL-5™ sheets, please see section “Curving of Steel Decks”.

Maximum Sheet Length

Sheets are supplied custom cut. See section “Thermal Expansion and Contraction of Steel Sheeting”.

Valley Fastener Location (Wall Only)

4 Fasteners per sheet – Internal and end supports

Table TL FS NC 001

Note:
1. Do not use punches to form fastener holes. AQUABLOK™ System

The maximum recommended support spacings are based on testing in accordance with AS 1562.1:1992, AS 4040.1:1992 and AS 4040.2:1992. 

Roof spans consider both resistance to wind pressure and light roof traffic (traffic arising from incidental maintenance). Wall spans consider resistance to wind pressure only. 

The pressure considered is based on buildings up to 10m high in Region B, Terrain Category 3, Ms=0.85, Mi=1.0, Mt=1.0 with the following assumptions made: ROOFS: Cpi=+0.20, Cpe=-0.90, Kl=2.0 for single + end spans, Kl=1.5 for internal spans. WALLS: Cpi=+0.20, Cpe=-0.65, Kl=2.0 for single spans, Kl=1.5 for internal spans. These spacings may vary by serviceability and strength limit states for particular projects. 

Fastening Sheets to Supports

TL-5™ profile is pierce-fixed to timber or steel supports. This means that fastener screws pass through the sheeting. 

You can place screws for TL-5™ cladding through the crests or in the pans. To maximise watertightness, always place roof screws through the crests. 

For walling, you may use either crest or pan-fixing. 

Always drive the screws perpendicular to the sheeting, and in the centre of the corrugation or rib. Don’t place fasteners less than 25mm from the ends of sheets. 

Side Lap Fastening

The edge of TL-5TM cladding with the anti-capillary groove is always the underlap (see figures below). It is generally considered good practice to use fasteners along side-laps however, when cladding is supported as indicated in maximum support spacings, side-lap fasteners are not usually needed for strength. 

End Laps

End-laps are not usually necessary because TL-5TM cladding is available in long lengths. If you want end-laps, seek advice from your local Fielders representative on the sequence of laying and the amount of overlap. 

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

It is usual to allow roof sheets to overlap into gutters by about 50mm. If the roof pitch is less than 25° or extreme weather is expected, the pans of sheets should be turned-down at lower ends, and turned-up at upper ends by about 80°. Refer to section “Flashings, Cappings & Ends of sheets”.

Sheet-Ends on Low Slopes

When TL-5™ cladding is laid on slopes of 5° or less, cut back the corner of the under-sheet, at the downhill end of the sheet, to block capillary action. 

Curving

For details regarding spring fixing and crank curving of TL-5™ sheets, please see section “Curving of Steel Decks”.

Maximum Sheet Length

Sheets are supplied custom cut. See section “Thermal Expansion and Contraction of Steel Sheeting”.

Side Lap Fastening

It may be necessary to use side lap fasteners at mid spans when using TL-5TM at maximum spans. These will help to hold the sheet laps firmly in place and maintain a weatherproof joint.

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.

Load Span Tables

The allowable spans have been determined from tests carried out in accordance with the following Australian Standards (wind load available by region): AS 1562.1 :1992, “Design and installation of sheet roof and wall cladding - Metal” and AS 4040:1992, “Methods of testing sheet roof and wall cladding”.

Wind Pressure Capacities

TL-5™ cladding offers the full benefits of the latest methods for modelling wind pressures. The wind pressure capacity table is determined by full scale tests conducted at Fielders' NATA-registered testing laboratory, using the direct pressure-testing rig.

Testing was conducted in accordance with AS 1562.1:1992 Design and installation of sheet roof and wall cladding— Metal, and AS 4040.2:2002 Resistance to Wind Pressure for Non-cyclonic Regions.

The pressure capacities for serviceability are based on a deflection limit of (span/120) + (maximum fastener pitch/30).

The pressure capacities for strength have been determined by testing the cladding to failure (ultimate capacity). These pressures are applicable when the cladding is fixed to a minimum of 1.0mm, G550 steel. For material less than 1.0mm thick, please contact your local Fielders representative.

 

Figure TL NC 002 End Spans, Internal Spans and Overhangs illustrates the terminology end spans, internal spans, and overhangs and their reference to the supporting substructure. This terminology has been used in the following Maximum Recommended Span and Wind Load Capacity tables. Long lengths and a special anti-capillary groove in the side-lap allows you to use TL-5 cladding on roof pitches as low as 2° (1 in 30).

Pierce Fixing

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.

Notes:
All fasteners used externally should be fitted with an EPDM seal (washer). Do not use punches to form fastener holes.

Fastener Spacings - Non-Cyclonic

Table TL FS NC 001

Note:
1. Do not use punches to form fastener holes. AQUABLOK™ System

The maximum recommended support spacings are based on testing in accordance with AS 1562.1:1992, AS 4040.1:1992 and AS 4040.2:1992. 

Roof spans consider both resistance to wind pressure and light roof traffic (traffic arising from incidental maintenance). Wall spans consider resistance to wind pressure only. 

The pressure considered is based on buildings up to 10m high in Region B, Terrain Category 3, Ms=0.85, Mi=1.0, Mt=1.0 with the following assumptions made: ROOFS: Cpi=+0.20, Cpe=-0.90, Kl=2.0 for single + end spans, Kl=1.5 for internal spans. WALLS: Cpi=+0.20, Cpe=-0.65, Kl=2.0 for single spans, Kl=1.5 for internal spans. These spacings may vary by serviceability and strength limit states for particular projects. 

Fastening Sheets to Supports

TL-5™ profile is pierce-fixed to timber or steel supports. This means that fastener screws pass through the sheeting. 

You can place screws for TL-5™ cladding through the crests or in the pans. To maximise watertightness, always place roof screws through the crests. 

For walling, you may use either crest or pan-fixing. 

Always drive the screws perpendicular to the sheeting, and in the centre of the corrugation or rib. Don’t place fasteners less than 25mm from the ends of sheets. 

Side Lap Fastening

The edge of TL-5TM cladding with the anti-capillary groove is always the underlap (see figures below). It is generally considered good practice to use fasteners along side-laps however, when cladding is supported as indicated in maximum support spacings, side-lap fasteners are not usually needed for strength. 

End Laps

End-laps are not usually necessary because TL-5TM cladding is available in long lengths. If you want end-laps, seek advice from your local Fielders representative on the sequence of laying and the amount of overlap. 

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

It is usual to allow roof sheets to overlap into gutters by about 50mm. If the roof pitch is less than 25° or extreme weather is expected, the pans of sheets should be turned-down at lower ends, and turned-up at upper ends by about 80°. Refer to section “Flashings, Cappings & Ends of sheets”.

Sheet-Ends on Low Slopes

When TL-5™ cladding is laid on slopes of 5° or less, cut back the corner of the under-sheet, at the downhill end of the sheet, to block capillary action. 

Curving

For details regarding spring fixing and crank curving of TL-5™ sheets, please see section “Curving of Steel Decks”.

Maximum Sheet Length

Sheets are supplied custom cut. See section “Thermal Expansion and Contraction of Steel Sheeting”.
