Sheets are cut to your specified lengths, subject to the following allowable range:
| Standard sheet length range | 1.0 m to 10.0 m |
| Minimum sheet length* | 0.8 m |
| Maximum sheet length* | 12.0 m** |
| Maximum unsupported length of sheet | 0.5 m |
*Any non-standard sheet lengths may incur additional manufacturing, packaging and handling/delivery charges.
** Sheet lengths up to 14.0 m may be possible, depending on full order details. Please discuss with our sales office prior to order placement.
D38 profile can be used to form a fully curved roof. Curving data as follows:
| Minimum convex self-curve radius | 45.0 m* |
| Minimum crimp curve radius | 0.3 m |
| Maximum length of crimp curved sheet | 6.0 m** |
*The self-curve radius is meant as a guide only as this figure is dependent on material thickness, sheet length and purlin spacings.
** The maximum length of crimp-curved sheets is dependent on the type of curve.
The D38 profile will be manufactured with a minimum straight leg of 150 mm at each end of the sheet. Please contact our sales office to discuss all curved sheet properties prior to order placement.
