The strength of steel
The mobile tunnel framework is made of
strong galvanized rectangular sections
joined by bolts with the aid of appropriate
ribbed steel plates. A tight trestle forms a
sturdy framework around which the cover
will be then securely attached.
Over 90% of the tunnel is bolt-assembled;
this method provides a number of advan-
tages compared to traditional welding,
including certainty of resistant sections,
modularity in transport, and interchange-
ability of damaged pieces.
Nearly all models and types in the
catalogue are equipped with heavy duty
wheels for manual or motorized move-
ment: this makes the tunnels mobile, and
therefore easier to add to already built
structures where construction expansions
are not possible.
The tunnels are manufactured and
calculated to withstand snow loads up
to 150 kg per square metre, and wind
loads up to approx. 60 kg per square
metre.
When requesting an estimate,
customers should specify the installation
area and indicative altitude of the location.
A special design/inspection may be
required.
