all kinds of special truss designs. All our trusses are available in a range of

50x2, 48x3, 50x3 or 50 x 4.
A complete circle is always delivered in parts. You will find a list of
standard possibilities with regard to dimensions and the number of parts
in this brochure. For the number of parts we always advice our customers
a multiple of four, so the possibilities in use of the circle is increased .
We advise our customers to not make the bent parts longer than 3.5
The number of parts can be increased or decreased on request of the
customer as far as this is technically possible. It is also possible to buy a
part of a circle.
Interal T.C. circles are always manufactured with great accuracy. This
makes it possible to fit a part at any place of the whole. Parts of different
circles that have the same size can be interchanged. This enables problemfree
replacement of a defective part.
