"Wide-span 'Curved
Rafter' truss series livestock shelters"

"The 10.65m (34'10") and 9.2m (30'2") Ultraspan
Ecoshelter provides the livestock farmers with further improved flexibility".
This model's cosecant curved rafter portal truss
design offers uncluttered "above head" workspace and allows relatively
large machinery to be operated inside the Ecoshelter with ease.
The truss concept also dramatically limits dust
collecting surfaces and perching points for insects and birds thus promoting
a more hygienic working environment.
Ultraspan Ecoshelter can optionally be supplied
with a continuous rack and pinion ridge roof vent system for greater year
round control. This may be manually operated or fully automated for
accurate 24 hour environmental control. Eziwinder roll up sidewall
ventilation may also be fitted as an option in both manual or automatic
form.
The Ecoshelter 10.65m (34'10") and 9.2m (30'2")
models are supplied standard with super-long life Duraflex heat reflecting
film or a reinforced roof cladding, which lasts for up to 10 years.
