Cable-stayed
bridges are more and more
gaining in favour firstly because they make
possible the building of fairly large spans in
an economical manner and secondly on
account of the way in which they harmonize
with the environment and the impression
they create.
The economics of these bridges
has in recent years improved appreciably
due to the technical advances which have
been achieved, especially in cable-stayed
bridges of concrete.
Road and rail bridges and also footbridges
can be constructed as cable-stayed
bridges. In many cases the bridge deck ie of
concrete, while in other cases, especially
where the spans are very great It Is of steel.
Composite girders ere also built.
Siak
Cable-stayed Bridge, Indonesia
An important element of a cable-stayed
bridge represented by the stay cables
themselves that can be constructed in
various ways. The success of cable-stayed
bridges is, however, to no smell measure
due to the use of high-strength steels for
the stays, especially in the form of strands
which offer particular advantages.
Some bridges already constructed
or at present under construction with VSL
Stay Cables.

Our Single
Strand Installation System is renowned for its high degree
of corrosion resistance, its ease of installation (strand-by-strand),
but most importantly, each strand can be individually stressed,
inspected and replaced.

Our service in stay cables projects include detailed
design of cable-stayed structures, construction
engineering assistance, manufacturing
and testing of systems, installation
and on-site supervision.
Stressbar
Stay Cables
VSL stressbars are particularly suited to small or lightly loaded stay
cable bridges. They can be provided with a simple but effective
corrosion protection system using an inorganic zinc silicate primer
system together with a polyurethane final coat.
Typically stressbar stays will require couplers as the bars are
manufactured in lengths up to a maximum of 12 metres. The coupler has
tapered ends and in place blends with the remainder of the stay.
The coupler can also be supplied as a turnbuckle, in order to tighten
the bars. In this configuration the bars are manufactured with a left
and right hand thread.
