Superior formability and a great showroom finish start with clean, consistent steel with precise chemistry

To produce sheet products with superior internal properties, surface quality and formability, it is essential to begin with world-class steelmaking. The three Basic Oxygen Furnaces (BOFs) at Burns Harbor rely on sophisticated computerization to produce liquid steel designed for specific automotive applications. Continuous testing, specialized ladle treatments and continuous casting assure precise control of steel composition, temperature, cleanliness and soundness.

Vacuum degassing improves steel properties
Vacuum degassing enables Burns Harbor to produce ultra-low carbon steels such as interstitial-free (I-F) steels which provide optimum formability.

Continuous casters produce internally clean slabs with excellent surface quality
Burns Harbor's two continuous casters produce slabs for rolling into automotive sheet steel. The outstanding showroom finish of auto body panels begins with automatic mold-level control in the casting process.

A continuously updated hot strip mill makes quality bands
Advanced computer controls, a scanning X-ray gauge, and special heating practices aid manufacture of hot bands for production of cold-rolled and coated sheet steel.

A blemish-free surface with long-lasting good looks comes from high technology rolling, annealing and state-of-the-art coating processes.

Burns Harbor cold-rolled sheet offers superior dimensional accuracy, flatness and surface quality
The 80-inch tandem mill at Burns Harbor maintains precise control of thickness using a closed-loop system to automatically adjust the tension and speed of the strip passing through the mill, while also controlling the gap and force of the mill rolls.

Our Continuous Heat Treating Line (CHTL) produces steel with highly uniform mechanical properties - edge to edge, end to end, and coil to coil - and superior surface cleanliness. The CHTL can produce high-strength steel in yield strengths of 37 to 100 ksi.
