SAFETY

Thanks to the system sanddry – the drainage gutter has been studied to reduce the inconveniences linked to avoid eventual infiltrations of the water roof – it also guarantees, in case of eventual rising of the water for capillarity, that water is brought in the eaves without infiltrations, also in low slopes.

PRACTICALITY

The slab is provided with a sandsupport foot to facilitate assembly and avoid crushing the overlapping fret during installation;

SAND 35 IS AVAILABLE IN THREE DIFFERENT USEFUL WIDTHS

800 mm, 1000 mm or 1200 mm (L1, L2, L3). Sheets are produced in precision lengths, according to specific customer requirements.

THE FOLLOWING APPLICATIONS ARE AVAILABLE ON THE INSIDE

SANDnodrip non-woven fabric with anti-condensation function, or SANDcontrol non-woven fabric with anti-noise and anti-condensation function.

TECHNICAL DROWING

APPLICATIONS

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

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

The TESTS performed on the products are:

↓ Fire resistance test
↓ Rain-induced noise test

SANDCONTROL - ANTI-NOISE AND ANTI-CONDENSATION CLOTH

-SANDcontrol is a special non-woven cloth with inc
ly 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

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

The TESTS performed on the products are:

↓ Fire resistance test
↓ Rain-induced noise test

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. The succession, the angular incidence and the pitch of the notches determine the value of the bending radius, which can be constant for the entire length of the sheet or with a variable value in the various sections of the same length.

-Notching can be concentrated on one or more parts of the length, giving rise to particular shapes mixed curved/straight or with irregular bending. -The curved slabs obtained in this way are mainly used in the creation of roofs with regular or irregular curved section, cusp section, with "Y beams", etc.

TECHNICAL SPECIFICATIONS

- Bending radius = min. 500 mm
- Footprint pitch = variable
- Length = min. 300 mm

CONSTANT/VARIABLE RADIUS

- On request from mm 300 on sand 20 and sand 28 profiles
- On request from mm 400 on sand 35, sand38, sand 40/200 - sand 40/250 profiles

PROCESSING AVAILABLE ON THE FOLLOWING PROFILES

- SAND 20
- SAND 28
- SAND 35
- SAND38
- SAND 40/200
- SAND 40/250
- SAND A55 P600

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.).
