Steel Roof Batten

STEEL ROOF BATTENS are the versatile and easy-to-use batten choice that’s compatible with all roof cladding materials.

These strong, light steel sections can be fixed directly to rafters using screws or nails through the flanges. Roof cladding is fixed to STEEL ROOF BATTENS using self drilling screws.

PRINCIPLE

Layout and use STEEL ROOF BATTENS just as you would traditional timber battens. They can be fixed directly to rafters using screws or nails through the flanges. Roof cladding is fixed to STEEL ROOF BATTENS using self drilling screws.

ADVANTAGES

STEEL ROOF BATTENS are increasingly popular with builders, because of their consistent quality, dimensional stability and resistance to termite attack.

LABOUR AND COST SAVINGS

STEEL ROOF BATTENS are locally rollformed from coated steel to produce a low cost building material that allows fast fixing to frame members, to minimise labour costs.

DESIGN FLEXIBILITY

STEEL ROOF BATTENS give design freedom for new buildings and simplify alterations, additions and renovations. STEEL ROOF BATTENS are also suitable for other applications including framing for van bodies, floor stiffeners, bracing, awning support frames, furring channel and shelving.

HANDLING AND STORAGE

STEEL ROOF BATTENS should be kept dry and stored under cover and clear of the ground. To maximise life expectancy, components which become wet should be separated and air dried as soon as possible to remove any moisture.

COMPATIBILITY

STEEL ROOF BATTENS can be used with all roof cladding materials and in conjunction with other framing materials such as timber.

PERFORMANCE

ROOF BATTEN – MAXIMUM SPANS AND SPACING (NON-CYCLONIC)

Maximum Span – 1200mm
Maximum Spacing – Internal Spans – 1500mm
End Spans (Up to 900mm Span) – 1200mm
Note: The batten spacing must not exceed the manufacturer’s Maximum Recommended Support Spacing for the Roof Cladding material.

These values are for buildings located under the following conditions as specified by AS.1170 Part 2, SAA Wind Code.
Area – Non-Cyclonic Maximum Building Height – 5m
Wind Velocity – 50m/s
Internal Pressure Coefficient – +0.8
Terrain Category – 3

ALLOWABLE WIND PRESSURE

For roof s subject to different wind pressures and conditions, calculate the actual wind pressure from AS. 1170 and then determine the span required from the table below.

INSTALLATION

FIXING TO HOUSE FRAME:

Timber Truss 2x12x40 T17
Metal Truss 2x10x16 TEKS

FIXING OF ROOF SHEETING

Refer to Manufacturers Recommended Fasteners and Fixing Details for Roof Sheeting.

LAYING AND LAPPING OF STEEL ROOF BATTENS

To minimise cutting, lay all battens in one direction, starting from one end. (Hip Valley Roofs – lay Battens starting from Valley.)
