| 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.
