TOPCOR Services, Inc. is suited for Structural steel restoration in industrial and public applications. Structural steel restoration is required when the steel structural members are damaged or attacked by chemicals. Structural steel restoration is the rebuilding of the steel members using equivalent strength steel plates seal welded or stitch welded to the exposed and damaged flanges and webs.

Structural steel restoration will involve a design engineer. TOPCOR works with a number of design engineers and can contact them for your project. A design engineer is required to design the plates and determine the final load capacity of the restored member. The new steel plates can be undersized (thinner then the flange) or oversized (wider then the flange) to position the weld on the flange or on the edge of the flange on the existing steel member. The web plates are positioned in the center and have to have clearance for a properly sized weld to be effective. Structural steel restoration can be done during outages, turnarounds, and during the replacement of vessels or other members.

Structural steel restoration is done first by blasting or cleaning the steel mechanically. This initial step is done to remove as much contaminants on the surface as possible. It also serves to expose the extent of the damage. After cleaning the steel, an inspection documenting the damage and corrosion is completed (see our survey matrix). The results of the inspection are given to an engineer for analysis. The engineer will design the plating required. The plates are then welded into final position by TOPCOR.
