Tunnel for storage use

Our tensile structures could be used as stables for the breeding of cattle and sheep or goats, but originally they were designed to be used as deposits, in place of the classic concrete structures.

Our tunnels are certifiable and calculable, in line with current Italian and European regulations (DM 2008 / UNI EN 13782), and considered structures of the removable type, with a temporary nature.

We offer two types of structures, different from each other, and each with its own characteristics.

The first type is the ARC TUNNEL.

It is a self-supporting structure with a single arch, with columns anchored to the ground by single or double picket.

The load-bearing structure consists of a galvanized steel section (measures 70×70 – 80×80 – 100×100), with heads and arches connected to each other and braced.

The pitch between the columns can vary from 1.5 to 2 m, depending on the zone loads.

The second type is the TUNNEL VERTICAL.

This is also a self-supporting structure with arched roof and vertical columns, fixed to the ground by means of a six-hole plate and relative stakes in the case of soil or, in the case of concrete, a plate complete with mechanical and chemical fixings.

The reticular structure is composed of steel profiles (size 50×50) welded to each other and hot-dip galvanized after processing, 3 m step with heads and arches connected to each other and braced.

Both are covered with a canvas made of high strength polyester woven, PVC coated on both sides, with a weight of about 700 gr / sqm.

This is a self-extinguishing “Class 2” sheet which, placed in contact with the flame, carbonises without transmitting it and without releasing incandescent particles (does not burn); if the flame fails the carbonization stops by itself.

It is usable with temperatures from -30 to +70 ° C, and has a tensile strength of about 280 DaN / 5 cm, and tear resistance about 32DaN.

For each of the two structures, various accessories are available, which improve ventilation or insulation: ventilation screen, side mesh windows or on gable, fixed headers, sliding doors, nets or side openings.

Our technicians are always available to advise the best solution for each need.

Regulation of the microclimate in the stall barn and natural ventilation

The summer season is just around the corner, and with it, the needs of farm cattle become even more apparent. The observation and management of dairy cows is, from their very first moments of life, an increasingly delicate process that requires constant updating and maintenance to ensure that their environment is welcoming and conducive to … Continue reading “Regulation of the microclimate in the stall barn and natural ventilation”
