sand40/250

The quintessential standard 5-corrugation sheet. Resistant, convenient, and adaptable.

SAND 40 250 REV GRANDE

SAND 40-250

SAND 40/250 corrugated metal sheet is one of the most popular standards for roofing profiles.

Its main features are:

  • Affordability: develops 1000 mm of useful width with an overlap percentage of 5%;
  • Safety: thanks to the SANDdry system, the drainage gutter, studied to reduce the inconveniences linked to possible water infiltration. In case of potential rising of the water for capillarity, it guarantees that the water is brought in the eaves without infiltration, even in case of low slopes;
  • Adaptability: it is compatible with the most common profiles of insulated panels and accessories;
  • Resistance: 40 mm high frets provide outstanding load-bearing performance.

SAND 40/250 is suitable for use on both civil and industrial coverings.

The possible bending processes are: fixed radius bending, variable radius bending.

The following applications are available on the inside: non-woven fabric SANDnodrip with anti-condensation function, or non-woven fabric SANDcontrol with anti-noise and 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:

Anti-noise and anti-condensation bitumen sheath

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
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.).
