The Challenge

A customer is a large structural steel and ductwork specialty contractor in the construction industry. They manufacture I-Beams and H-Beams made from structural steel using a Peddinghaus with soluble oil mist coolant. The customer’s annual production is over 100,000 tons (90,718.5 metric tons) of steel beams, bars, and ductwork.

The customer wanted to increase productivity while decreasing the overall cost of production.

The Original T-A structural steel solution reduced the machine’s cycle time and also lowered the cost of production while increasing the overall productivity.
