About MPI - West Central Manufacturing

Based in Rapid City, South Dakota, MPI has been producing custom steel doors and frames for over 38 years. The company operates as a global manufacturer serving architects and designers with few constraints beyond imagination. MPI fabricates doors and frames in thicknesses from 0.042 to 0.093 inches using commercial-grade cold-rolled, A60 galvanneal, G90 galvanneal, and stainless steel. Products achieve fire ratings up to three hours positive pressure and carry Underwriters Laboratories labels. The facility employs AutoCAD engineering systems and databases alongside an experienced engineering staff to integrate complex hardware and support architectural firms on intricate door and frame systems. Every unit is handcrafted to exact specifications rather than assembled from modified stock components. Its product lines include bullet-resistant, FEMA-compliant, lead-lined, sound-rated (STC), thermal-rated, windstorm-rated, and temperature-rise doors, as well as polystyrene and polyurethane insulated cores. Architectural firms regularly engage MPI’s engineering team for design assistance on complex installations. MPI emphasizes that “custom” means fully custom manufactured—each door and frame is handcrafted to exact specifications without pulling components from a shelf. The company’s mission stresses professional, ethical, and dependable operations, with a commitment to continuous improvement and partnerships that exceed customer expectations.
