SAND 28 REV GRANDE

SAND 28 PROFILO REV 1

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.

Anti-condensationTNT

SANDnodrip - Anti-condensation cloth

SANDnodrip is a special non-woven fabric cloth chemically bonding specific elements that create a highly porous surface with excellent moisture absorption properties.

These characteristics prevent the roof from dripping, thanks to polyester fibres and microbeads in the felt that absorb and collect the forming condensation.

SANDnodrip corrugated metal sheets are characterised by a fire resistance class A2-s1, d0.


TECHNICAL INFORMATION about SANDnodrip:

  • Material = TNT 100% polyester fibre
  • Nominal thickness = < 1 mm
  • Colour = grey
  • Fire resistance class = A2 - s1, d0


The TESTS performed on the products are:

SANDcontrol - Anti-noise and anti-condensation cloth

SANDcontrol is a special non-woven cloth with increased density, which makes it possible to significantly reduce the noise caused by outdoor weathering.

In addition, it is specially designed to offer excellent performance in absorbing any condensation that may form.

The reduced thickness allows you to carry out interventions, even in case of recovery or renovation, without raising the roof package.

The corrugated sheets with SANDcontrol application are characterised by fire resistance class C-s1, d0.


TECHNICAL INFORMATION of SANDcontrol:

  • Material: TNT 100% polyester fiber
  • Nominal thickness = 2-3mm
  • Nominal thickness= 200 g/m2
  • Color = Grey
  • Fire resistance class = C - s1, d0

Processing
Maxi-fold

For a shed-type structure

This process, performed on a bending machine with a special shaped die, produces a single transversal fold on the trapezoidal sheet with an angle greater than or equal to 87°.

All the deformations generated are contained and controlled by the special conformation of the mold, so as to make the finished products perfectly suitable, equal an...

Notching

For variable bendings

Bending takes place by means of a series of transversal impressions to the trapezoidal sheet (notches) that produce a series of bends with constant/variable pitch.

The notches are designed and executed to allow a correct absorption of the material stresses due to deformation, without loss of rigidity of the trapezoidal element...

Calendering

For fixed radius bending

Micro impression calendering is a bending process that allows a controlled deformation of trapezoidal sheet metal until the desired radius of bending is obtained. Constant radius curved sheets are mainly used in the creation of curved roofing (on metal structures, prefabricated Y-shaped tiles, etc.).
