- It has a special anti-capillary groove in the side lap allow use on roof pitches as low as 2° (1 in 30)
- Can be used for both roofing and walling applications
- Long, straight lengths can be lowered into place and easily aligned
- Strength, spanning ability, lightness and rigidity permits wide support spacings to be used with safety
- Long lengths allow one sheet from ridge to gutter without end laps.
Common Uses of this product
Roofing and walling in industrial, commercial and domestic applications

- Minimum recommended roof pitch is 2 degrees
- 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.

Maximum Support Spacings
The maximum recommended support spacings are based on testing in accordance with AS1562.1-1992, AS4040.1-1992 and AS4040.2-1992.
Roof spans consider both resistance to wind pressure and light roof traffic (traffic arising from incidental maintenance).
Wall spans consider resistance to wind and 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 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.

- 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.
