About Alexandria Industries

Alexandria Industries manufactures custom aluminum extrusions and related components for OEM products. Headquartered in Alexandria, Minnesota, it lists U.S. operations for extrusion, precision machining and plastics in Minnesota and Indiana. Its approach connects extrusion design with the downstream work needed to turn a profile into a usable component or assembly. Engineers can discuss alloy and section geometry alongside machining, welding, finishing and plastic injection molding requirements. The company’s contact page links to its quotation workflow and provides sales contacts for routing a new design or recurring production program.

Services

AI illustration of aluminum extrusion.

Aluminum extrusion

Produces custom profiles using 6000-series aluminum alloys. Design-for-manufacturing support considers wall thickness, alloy choice and surface requirements before extrusion, with downstream processes available for the finished component.

AI illustration of cnc machining.

CNC machining

Machines extrusions and other components to add the precision features required by the final product. CNC equipment and process planning connect the extruded profile with finished holes, surfaces and other customer-defined geometry.

AI illustration of mig welding.

MIG welding

Joins component assemblies using TIG and MIG processes. Welding complements extrusion and machining for commercial and industrial products, with the method and production approach selected for the materials and assembly requirements.

AI illustration of injection molding.

Injection molding

Manufactures custom molded plastic components for OEM products. The service can be considered alongside the company’s metal processes when a product requires both plastic parts and extruded or machined components.

AI illustration of kitting.

Kitting

Assembles manufactured components and supports packaged kits. The scope can include hardware, labels and multiple parts, connecting individual manufacturing operations with the customer’s required delivery configuration.
