MST Steel is a leading supplier and processor of high-strength, specialty, and automotive-grade flat-rolled steel, serving manufacturers across North America since 1977. As an experienced Tier 1 and Tier 2 partner, MST Steel supports the automotive, construction, HVAC, furniture, communications, and industrial sectors with dependable material supply, precision processing, technical expertise, and responsive service.

Across three strategic facilities in Michigan and Kentucky, MST Steel maintains an 85,000-ton on-site inventory of galvanized and non-coated steel, including hard-to-find grades and advanced materials such as High Strength Low Alloy (HSLA), Dual Phase (DP), and TRIP steels. Three 72-inch slitting lines provide precise dimensional control and superior edge quality, while cold-reducing capabilities address tight-gauge and camber-critical requirements.

Quality is supported by an on-site metallurgical laboratory performing chemical analysis, hardness, ductility, yield strength, and tensile strength testing. Continuous X-ray gauge measurement, IATF 16949-certified processes, and detailed material certifications provide confidence and traceability with every shipment.

With strong relationships across major domestic steel mills, rapid response capabilities, and company-controlled Michigan deliveries, MST Steel helps manufacturers reduce supply risk, meet demanding specifications, and keep production moving throughout the USA, Canada, and Mexico.
