Economical Estimation Tips
For Roofing
- Number of sheets (N) = (Slope Length - 0.2) / 2.8
- Maximum lap loss (M) = (N - 1) × 0.2
- Max Sheet Length (P) = L + M (rounded up to next multiple of 0.25)
For Wall Cladding
- Optimal Sheet Length = 1.75 m
- Purlin/Rail Spacing = 1.6 m
- Utility and Store Room Walls
