What MPI does

MPI (Metal Products Inc.), operating as The MPI Group, LLC, is a custom hollow metal door and frame manufacturer founded in 1980 and headquartered in Corbin, Kentucky. The company designs, engineers, and fabricates steel doors and architectural frames to exact architectural specifications, using AutoCAD-based engineering systems and a documented quality assurance program covering order entry through delivery. Its product portfolio spans four core door constructions (polystyrene-core, polyurethane/polyiso, steel-stiffened, and temperature-rise) paired with standard frames and custom elevations, plus an extended specialty line covering UL 752 bullet resistance, FEMA 361/320 and ICC 500 safe-room assemblies, lead-lined radiation protection, STC 26-53 sound-rated assemblies, stainless steel, thermal-break frames, and Florida Building Code-approved windstorm products.

MPI sells exclusively on a project-specification basis to architects, contractors, and distributors, with end-customer concentration in education (universities, K-12), healthcare (hospitals, medical offices, treatment centers), government (police, fire, municipal), hospitality, commercial, and multi-family residential construction. The company is SDI Certified and UL Listed, complies with ANSI A250, ASTM, NFPA, and Florida Building Code standards, and supports LEED projects through published EPDs, HPDs, and recycled-content documentation. Its geographic footprint includes manufacturing in Kentucky plus regional operations in Michigan and South Dakota, with distribution extending nationally and internationally.

As a wholly-owned subsidiary of ASSA ABLOY (Nasdaq Stockholm), MPI operates within a global door opening solutions conglomerate and benefits from parent-company scale and procurement leverage, though revenue and detailed financials are not publicly disclosed. Pricing is quote-based reflecting the custom nature of each order, and the company does not sell through any public-facing API or software product.
