Steel Products — 355 Specifications Across 10 Categories
Quality steel materials and comprehensive inventory management for all industries
Michigan's Trusted Steel Supply Partner
Ameristeel is a family-owned, ISO 9001:2015 certified steel service center headquartered in Metro Detroit, serving automotive OEMs, Tier 1 suppliers, and metal fabricators across the United States. Our comprehensive steel product catalog covers 355 individual specifications across 10 major standards organizations — including AISI, ASTM, SAE, and OEM-specific specs from Ford, GM, Tesla, Rivian, Lucid, and Fiat/Chrysler.
Whether you need cold rolled, hot rolled, galvanized, galvanneal, electrogalvanized, or aluminized steel, Ameristeel stocks a deep inventory of flat-rolled steel products in a wide range of thicknesses, widths, and grades. Our dedicated purchasing team works directly with domestic mills to source material quickly — including hard-to-find automotive grades that other distributors struggle to locate.
Every coil and sheet that enters our facility is immediately tested through third-party accredited laboratories. We triple-test (ID, OD, and Coil Center) to verify that material properties remain consistent from beginning to end. This rigorous testing protocol, combined with full material traceability, ensures that every pound of steel we sell meets your exact specification requirements.
Our Inventory Excellence
With 150,000+ tons of steel sold and 10,000+ completed jobs, Ameristeel has built the reputation of having a "best-in-class" inventory. We have been able to trend material needs and stock based on current demand. This allows us to offer hard-to-find material with very quick turnaround times.
With a dedicated purchasing agent and direct relationships with all of the domestic mills, we are able to locate and purchase material that we don't have very quickly.
Every pound of steel that enters our facility is immediately tested, utilizing 3rd party accredited laboratories.
