Millwork manufacturers operate production facilities that cut, shape, plane, and finish wood into moldings, flooring, stair components, shutters, mantels, cornices, and similar architectural products. Operations typically involve industrial woodworking equipment — planers, shapers, routers, lathes, and saws — with significant wood dust generation, often alongside staining or finishing processes. Products are generally sold to distributors, building supply retailers, contractors, or directly to commercial construction projects.
