SAND28
SAND 28 is one of the most versatile profiles of the range, multi-corrugation, characterised by trapezoidal grooves with constant pitch. Suitable also for minimum slopes thanks to the lateral overlap of 1.5 grooves, it guarantees a high index of walkability and water flow rate as well as resistance to stress over time.
Its geometry makes it particularly suitable, in addition to traditional straight and curved roofing, for applications where aesthetic impact is crucial, such as building facade coverings or industrial false ceilings.
Our production facilities allow us to produce SAND 28 in three different useful widths: 680 mm, 900 mm or 1120 mm. In the 1120 mm version (L3), the incidence of overlapping is considerably reduced. The slabs are produced in precision lengths according to customer specifications.
The possible bending processes are: fixed radius bending, variable radius bending, shed bending.
The following applications are available on the inside: SANDnodrip non-woven fabric with anti-condensation function, or SANDcontrol non-woven fabric with anti-noise-anti-condensation function.
