What purlin spacing does each roof tile need?
Purlins support the roof tiles, and the spacing of each row depends on the tile size and weight. Steel purlins carry load well and do not shrink, swell or warp like timber battens, giving straight, neat tile lines.
Tile type | Size (cm) | Weight (kg/tile) | Purlin spacing (cm) |
|---|---|---|---|
Double-profile 120 cm | 50x120, 6 mm thick | 7.2 | 100 |
Double-profile 150 cm | 50x150, 6 mm thick | 9.0 | 130 |
Concrete tile | 33x42 | 4.05-5.2 | 31-34 |
Prima tile | 55x65, 5 mm thick | 3.9 | 50 |
Clay tile | 29x45 | 3.8 | 38 |
Example weights for a 25x61x25 mm steel purlin, 6 m long: 0.55 mm thick weighs 2.4 kg, 0.65 mm weighs 2.9 kg, 0.70 mm weighs 3.4 kg, and 1.00-1.60 mm weighs 3.8-5.0 kg per piece.
