38/980 Trapezoidal Sheet
| Type | : | Roof and Facade |
| Net Covering Width | : | 980 mm |
| Rib Height | : | 0.50 - 1.20 mm |
| Maximum Length | : | 16 m |
38/980 trapezoidal sheets can achieve efficient results at the roof cladding with optimum price. Strength and aesthetics is combined by the tracks between the ribs.
