Steel That Works as Hard as You Do.
Steel shapes form the structural backbone of modern industry. From heavy equipment frames to building skeletons, steel is unmatched for load-bearing strength, stability, and long-term economy.
At Aluminum Supply Company (ASCO), we carry and source a full range of carbon-steel profiles engineered for performance under pressure. Whether it’s a standard beam or a specialty section, every shape we supply meets rigorous dimensional and mechanical standards—because the foundation of any great project starts with solid steel.
Steel is where strength meets value. It’s machinable, weldable, recyclable, and able to endure decades of stress and environmental exposure.
Our inventory includes hot-rolled and cold-rolled grades selected for predictable forming, fabrication, and corrosion resistance.
ASCO stocks essential profiles and can source or fabricate any required geometry.
Corner reinforcement, bracing, and framing
Track systems, structural frames, and machinery bases
Versatile stock for bracing, plates, and supports
Round and square sections for railings, conveyors, and mechanical structures
The workhorses of construction and heavy fabrication
Finish Options: Mill, pickled & oiled, galvanized, or primed.

Note: Availability varies by shape—contact ASCO for current stock and lead times.
When the design calls for strength and reliability, steel delivers—and ASCO keeps it moving on schedule.



Steel is only as good as its cut, bend, and weld—and that’s where ASCO excels.
Our in-house fabrication floor turns raw stock into project-ready components with speed and precision.
From prototype parts to high-volume runs, we handle fabrication in-house or with vetted partners to keep your production streamlined and your tolerances tight.
ASCO’s steel supply network supports contractors, OEMs, and manufacturers across the Midwest.
Our reputation for responsiveness, quality, and on-time delivery makes us the go-to steel source when deadlines and standards matter.
Tough metal. Smart sourcing. Real results.
