World first: 50 metres free span in cold-rolled steel.
As a pioneer
in steel constructions, Frisomat
develops a 50m free span in cold-rolled steel. So far, steel constructions like
this, could go to a maximum width of 35 metres, in exceptional cases, up to 40 metres.
Test set-up on a 1:1 scale
theory into practice, Frisomat has mounted
a truss beam framework of 50m wide on its factory premises in Belgium.
Why a full-scale
test model ?
- To measure the bending (positive
camber), which theoretically is very difficult to predict
- To verify the solidity of the structure,
by suspending a ballast of 1.700kg onto the steel construction. The weight is
equal to the load of the steel purlins and roof sheeting.
- To suggest clear and tested assembly instructions
for our technicians
100% success rate
results of the test configuration turned out to be very successful. Despite the
ballast, the steel structure showed almost no bending or distortion. The
results were so good in fact, the concept doesn’t require any modification
whatsoever. Thanks to in-depth engineering, a new standard is set for
constructions in cold rolled steel.
Industrial warehouse of 6,250 m²
experience with the test configuration, the project becomes reality in the
autumn of 2012.
industrial building will serve as a warehouse in a South-American port
terminal. The project (125m long, 50m wide and 9m high) is custom-made for the
client. For example:
- One 8m wide canopy on the 125m
long sidewall of the warehouse
- One 8m wide canopy on the front
- 5 industrial sliding doors
- A mezzanine inside serving as office
The close proximity to
the sea, a very aggressive environment, requires a special PVDF coating. This
to guarantee the colour retention and the life span of the roof and wall sheeting.
High wind load
will be able to resist a wind load of 168km/h, which is the toughest standard
for South America. Because of this heavy load,
double and asymmetric columns are required to counteract declension. The truss
beam framework columns are providing extra reinforcements.
