What we do

Three disciplines.
One company.

Most steel packages pass through three different companies before they are complete. Ours don't. Casadei Steel details, fabricates and erects with its own people — so nothing gets lost between the model, the shop and the field.

Detailing

One of the largest detailing departments in Michigan, with more than 160 years of combined experience. We model in SDS/2, deliver BIM models to other trades for coordination, and work fluently in Bluebeam Revu and AutoCAD.
