45/900 Trapezoidal Sheet
| Type | : | Roof and Facede |
| Net Covering Width | : | 900 mm |
| Rib Height | : | 0.50 - 1.20 mm |
| Maximum Length | : | 16 m |
45/900 trapezoidal sheets with high strength, are used as cladding material in systems with higher spans and which are subject to heavy load forces. 45/900 is ideal for facades of heavy industrial buildings and for the inner layer in sandwich membrane roofs.
