|National Bridge Co. has been conducting heat straightening
repairs for over 25 years, in many states from the Midwest to
the East Coast, both on highway bridges and columns and trusses
in auto plants and warehouses. We are a reputable, insured,
safety conscious company, never failing to complete a project
to the client's satisfaction or having an on-site accident.
We are able to work a flexible schedule, including nights and
weekends, in order to work around heavy traffic volumes.
Besides repairing damaged members, we are also able to add,
or remove, camber from beams both erected and those waiting
to be erected, whether it's on-site or in the shop. This applies
to curved girders as well, as they often lose either camber
or curvature during shipping.
Many heat straightening repairs also require some welding,
and often the welding is an integral part of the repair, best
done in stages during the heat straightening. Using different
companies for the straightening and the welding can unnecessarily
add time and cost to a repair. National Bridge has two AWS
D1.5 certified bridge welders, enabling us to conduct the
entire repair in the most timely, and cost efficient, manner.
Our crew is a self-contained unit, and requires no additional
manpower or equipment from the client. In most cases, it is
most cost effective for the client to provide the traffic
control. However, we are able to provide our own single lane
closure if this is not feasible. In an emergency situation,
our crew can usually be on-site to begin work in as little
as 48 hours, depending on the location.
In addition to conducting the repairs, we can also act as
a consultant, assisting the client in determining if heat
straightening is a viable repair option, and assisting in
the design of the repair. Generally, we can consult on-site
within 48 hours of the request, and in an emergency situation,
can be on-site within 24 hours. While on-site inspection is
required for an accurate repair scope, more general information
can be obtained from adequate pictures through e-mail. To
