What Great Lakes Dock & Door does
Great Lakes Dock & Door (GLDD) is a Detroit, Michigan-based industrial services company founded in 2003 that specializes in the manufacturing, sales, service, maintenance, and repair of loading dock equipment and overhead doors. The company serves commercial and warehouse facilities in the US Midwest/Great Lakes region, with a stated headcount of 11-50 employees. Its product and service scope covers loading dock levelers, dock doors, industrial doors (coiling, cold storage, high-speed, sectional, specialty), trailer restraints, dock seals and shelters, forklift dock plates, and related installation work, supplemented by preventive maintenance and facility-management services.
The company has been acquired by MINER Corporation, a private strategic operating company that describes its mission as building the industry's first national network of service professionals for critical facility services and material handling equipment. As an acquired brand within the MINER portfolio, GLDD operates alongside approximately 14 other regional dock-and-door companies (including Star Equipment, MHC Systems, Pace Material Handling, New Jersey Door Works, K&K, and others) and contributes to a service footprint that spans 30+ US states under the MINER master brand, while retaining its own GLDD identity. The business model is a traditional commercial/industrial service model: equipment sales plus installation, repair, and recurring maintenance contracts with commercial facility customers. The company does not publicly disclose pricing, revenue, customer concentration, or financial information, and there is no disclosed proprietary technology, software platform, or AI/ML capability — the offering is labor- and equipment-driven industrial services rather than a technology product.
