The SAND 153 profile belongs to the family of "large span" profiles, which are particularly suitable for the construction of buildings characterised by medium and large structural steps.

Easy transport and handling, rapidity and simplicity of installation are the peculiar characteristics that distinguish them: the installation is completely dry, with variable fixing systems depending on the structure.

Compared to a traditional prefabricated solution in pre-stressed reinforced concrete, "large span" structural slabs have the following advantages:

TECHNICAL ADVANTAGES

High load-bearing capacity: a wide range of profiles with different parameters (height and pitch) are available, which can be produced in different thicknesses according to specific design requirements;

Greater safety: thanks to their low weight, they give the structure better anti-seismic behaviour;

Versatility: they adapt perfectly to any type of flat, curved or inclined structure.  Versatility: they adapt perfectly to any type of flat, curved or sloping structure. In the Perforated version they give the roofing package a high capacity for sound absorption.

ECONOMIC ADVANTAGES

Cost of construction: The structural system for large spans, thanks to its much lower weight, allows for the construction of buildings with smaller load-bearing elements, thus saving money.

Transport costs: the packaging and reduced dimensions of the corrugated sheets allow for the transport of a much larger quantity of material per vehicle, on average around 2000/2500 m2.

Labour costs: savings on labour costs due to the speed of laying and immediate static efficiency. The rapidity of laying and ease of handling allow considerable savings in labour costs and execution times.

All large span profiles are available in Positive, Negative and Perforated versions and can be supplied with the following applications on the inside: SANDnodrip non-woven fabric with anti-condensation function or SANDcontrol non-woven fabric with anti-noise and anti-condensation function.
