United Aluminum's Tradition of Quality

Ship on time; ship the quality of goods agreed upon; make every transaction merit a repeat order. This is the spirit that pervades our organization. Whether you order a pound or a carload, you are entitled to service, the quickest possible shipment and above all – United Quality.

We wrote these words in 1919 and remain true to this philosophy. Our passion for customer satisfaction led us to become the first general purpose aluminum rolling mill in North America to receive ISO 9002 registration.

United Aluminum’s rolling mills in 1919. United Aluminum began as a scrap and smelting company in 1891 and started rolling aluminum in 1915, making it the second oldest aluminum roller in America today.

Today… United Aluminum’s state-of-the art Sendzimir rolling mills deliver the closest, most uniform gauge control to ensure that your production runs are smooth and profitable.

United Aluminum Mill

Custom Rolled® Aluminum Coil

United Aluminum's Sendzimir Mills (Z-Mills) are a marvel of technology, innovation, and engineering experience. They produce the most consistent rolled aluminum gauge possible to the most exacting tolerances. United never stops improving our mills, finding ways to make even the best rolled aluminum coils in the industry even better. Our typical Z-Mill finish is brighter than a conventional 4-hi mill without extra cost. The Z-Mill is also capable of matching your mill finish. Ask us about rolled aluminum coil finish options.
Gauge Diagrams

Consistent Gauge Control

Here we can see a typical gauge distribution between aluminum coils rolled on a typical 4-hi mill versus the uniform gauge produced from United Aluminum's Sendzimir rolling mill. More consistent gauge end-to-end, coil-to-coil, and order to order means that you need fewer adjustments to run your equipment at high speed, and less setup between aluminum coils and orders.
Aluminum Slitter

Custom Slitting

United Aluminum has industry leading slitting, and some of the most talented aluminum coil slitting experts in the business. We can offer very tight width tolerances, specific coil OD ranges, large OD's up to 76”, and a variety of coil ID sizes and fiber or aluminum core types, as well as strippable plastic coating.
Custom Annealing

Custom Annealing
