Tunnel and Tarpaulin covers
Due
A team is in continuous training in way to propose and supply innovative and
up-to-date articles.
The
flagship product of our range are “Tunnels” which are structures quick to
produce and install, economical and lasting over time.
The
main structure is made of square and galvanized steel tubes that are connected
to each other by means of special bolted joints, forming an arch. This arch is
anchored to the ground by means of tubular galvanized steel fixed in the ground
for a depth that ensures stability based on the geotechnical characteristics of
the soil. The arches are positioned parallel to a variable distance, depending
on the type of tunnel, connected to each other by means of C-profiles placed
horizontally along the entire length of the structure. Every 3/4 arches is
placed a braced field made of galvanized steel plates. The cover is made of a
self-extinguishing 700 g / m2 PVC sheet, tensioned with ratchets anchored to
the base of each arch.
For
the installation of such structures it is necessary only a level ground, no
foundation works in concrete are necessary, and no excavations or land
recoveries.
Moreover,
if necessary, the structure can be dismantled and reassembled on another site
without altering the morphological characteristics of the ground.
The
first tunnels were intended to be simple deposits for raw materials and
equipment or machinery. Than they were used more and more even for the shelter
of animals, up to replace very well the classic buildings in concrete and being
used as stables in all respects.
Due A offers different types of Tunnel and tarpaulin covers:
“ARC
TUNNEL” ideal as fodder storage and raw materials
“VERTICAL
TUNNEL” for the storage of hay and storage of agricultural machinery
“SHEEPFOLD
TUNNEL” designed for the shelter of animals, both temporary and for long
periods
Widths
proposed are standard, while the length is modular and varies according to the customer’s
needs.
A
lot of additional elements can be applied such as side windows or on the gable,
dome and side nets that improve the internal ventilation and limit the
formation of condensation.
Furthermore,
each structure can be completed with fixed closures and sliding or rigid
sliding doors.
Given
the intended use, the characteristics of flexibility, lightness and materials
used, the structure is considered of a removable type with a temporary nature
in accordance with the UNI EN 13782 standard.
Finally,
our tensile structures guarantee snow and wind loads, as required by current
regulations.
