Corrugated 0.42BMT Zincalume Sheet

1. Measure the width of your roof or wall to find the amount of sheets you need to cover the building (i.e. the building is 7m wide)
2. Divide the length by 0.762 which is the sheet coverage (i.e. 7m ? .762 = 9.786 sheets) so round up to 10 sheets for this building.
3. Round up the result to the nearest whole number.
4. Measure the required sheet length up the gable or building for walls the height to find the required sheet length.
5. For roofs allow approximately 40mm into gutters and for wall sheeting allow approximately 30mm overlap at the base past the slab
6. Then choose your colour and quantity and your good to order.

Please note that this calculation is based on a standard sheet size, but the actual number of sheets required may vary depending on the specific dimensions, profile, and thickness of the sheets you are using. Factors such as overlaps, cutting allowances, and the shape or slope of your roof or wall can significantly impact the final quantity needed. For accurate results, carefully measure your area, account for any necessary overlaps, and consider the specific installation requirements. If you are unsure about your measurements or how many sheets you need, it is always best to consult a qualified roofing professional.
