Structural Steel is the backbone of fabrication.

Structural Steel
Structural steel is the primary support for the overall structure. From structural project drawings, AIW's design team creates detailed shop drawings of the individual components and integrates the finished component design into the 3D BIM project model. The component drawings are revised further per the 3D BIM analysis and manufactured by AIW personnel at its manufacturing facilities. AIW's ability to provide the full suite of metals products and manage the design and execution of all the connection points continues to provide a significant and compelling value-added benefit for the project owners and general contractors.Manufacturing structural steel components requires a high degree of accuracy in design and execution. Each part is custom manufactured to precise specifications. As building architecture becomes more complicated, the structural steel framework takes on a greater amount of characteristics unique to the project.
