Mueller Industries manufactures and distributes copper, brass, aluminum, and steel products globally, serving construction, HVAC, refrigeration, plumbing, industrial, and transportation markets through three business segments: Piping Systems, which produces copper tube and fittings for plumbing and air-conditioning applications; Industrial Metals, which manufactures brass rod, forgings, extrusions, and specialty components for OEMs; and Climate, which makes refrigeration valves, heat exchangers, and HVAC ductwork. The company generates revenue by selling these products at prices that fluctuate with raw material commodity costs, primarily copper, and attempts to pass through cost changes to customers through flexible pricing. Demand is driven by housing construction activity, commercial construction, repair and remodeling projects, and industrial and transportation applications.
