Innovative Solutions, Quality, and Performance Since 1936. We do the Impossible.

Our project managers give you peace of mind that steel will be on the job site to your schedule. We are accountable for providing oversight of the shop drawing process based on contract documents and specifications. We have strong ties to steel mills and an efficient production management operating system.

Production Execution: CU Case Steel Truss

CU CASE

For CU CASE, we executed a unique manufacturing capability that required boring a 2″ diameter cavity, 9″ deep at a compound angle to the girder, with our 250″ table vertical bridge mill.

Denver Botanic Gardens’ Tree Columns

The atrium portion of the project featured four “Tree” columns that utilized 60 total rolled and mitered beam members to create the intricate assemblies.  Vast and precise cutting & fitting of the members led to a clean but intensive erection process given the very tight tolerances required by the project details. The impressive finishes were achieved in our self performed AISC SPE-P1 Sophisticated Paint facility.
