Fully Equipped, Unmatched Capacity...
Our 1500 ton hydraulic press brake is among the largest in the Midwest. It's 28' bed gives us a forming capability that only a handful in the country have.

Many customers depend on our stress relieving, blasting and priming capabilities. Our stress relieving ovens provide what no other fabricator in the region can, complete control over one of the most critical aspects of the fabrication process. Our ovens are digitally controlled for precise stress relieving of our customers' fabrications.
