Structural Steel Erection & Refurbishment

Structural steel in industrial plants carries more than just static loads — it supports operating equipment under dynamic loads, thermal cycling, vibration, and in many cases, corrosive atmospheres that cause progressive section loss. MAC Industrial Services provides structural steel erection for new construction and capital projects, as well as repair and refurbishment of existing steel in operating facilities where degradation or damage has compromised structural integrity.

In the power generation and heavy industrial environment, the most demanding structural work occurs in the boiler structure, stack structure, cooling tower structure, and the platforms and access systems that maintenance crews depend on. MAC has direct experience with all of these applications — including the combination of restricted access, elevated work, and concurrent plant operations that make industrial structural work more complex than commercial construction.

MAC structural crews work from engineered drawings with the necessary qualifications for structural steel welding (AWS D1.1) and bolted connections (AISC 360). Where repairs involve existing code-designed structures, we work with engineers of record or provide structural engineering coordination to ensure that repairs restore structural capacity to the original design basis and satisfy applicable building and boiler codes.
