LYSAGHT SPANRIB® (Queensland Only)
Product Description and Features
LYSAGHT SPANRIB® cladding provides the benefits of long spanning, pierced-fix cladding, with excellent rainwater carrying capacity. It is available in Queensland only.
It has been designed for commercial and industrial applications where long span and fast installation are major requirements.
- Long lengths and a special anti-capillary groove in the side lap allow use on roof pitches as low as 1 degree for 0.48 mm BMT
- 820mm wide
- Can be used for both roofing and walling applications
- Each sheet only requires three fasteners per support
- Long lengths allow one sheet from ridge to gutter without end laps
Common Uses of this product
Roofing and walling in industrial and commercial applications
Warnings
- Available in Queensland only
- Minimum recommended roof pitch is 1 degree
- Walk only in pans and close or over the supports
- Ensure selection of suitable material for environmental conditions for maximum durability
- Lead and copper are not compatible with ZINCALUME® steel or COLORBOND® steel
- Read full details on Guidelines for using COLORBOND® steel & ZINCALUME® steel.

Spanning Tables
The maximum recommended support spacings are based on testing in accordance with AS 1562.1 - 1992, AS 4040.0 - 1992 and AS 4040.1 - 1992.
Roof spans consider both resistance to wind pressure and light roof traffic (traffic arising from incidental maintenance).
Wall spans consider resistance to wind and pressure only.

- For roofs: the data are based on foot-traffic loading.
- For walls: the data are based on pressures (see wind pressures table).
- Table data are based on supports of 1mm BMT.
The pressure considered is based on buildings up to 10m high in Region B, Terrain Category 3, M2=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 and end spans, Kl=1.5 for internal spans.
Walls:
Cpi=+0.20, Cpe=-0.65, Kl=2.0 for single and end spans, Kl=1.5 for internal spans.
These spacings may vary by serviceability and strength limit states for particular projects.
Capacity & Load Tables
LYSAGHT SPANRIB® 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 BlueScope Lysaght's 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 and AS 4040.2 - 1992, Resistance to wind pressures 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, Contact Us for advice.
