Our Legacy of Metal Expertise Since 1970
Larry Markwart founded Markwart Metals 50 years ago with a clear purpose: to provide personalized consulting services tailored to reviewing and resolving complex material supply challenges. Specializing in Brass, Bronze, Aluminum Bronze, Copper, Tool Steel, and Aluminum, Larry’s approach focused on going the extra mile to find and supply hard-to-source metals, building the business one customer at a time.
Today, as a second-generation family business, we remain committed to those foundational values and services. Our motto, “We solve sourcing issues and put your mind at ease,” reflects our dedication to customer-centric solutions.
Markwart Metals has grown into a leading supplier, boasting extensive inventories and the capacity for quick turnarounds. Our extrusion mills produce copper, brass, and bronze products in a wide array of shapes and sizes, including bar, tube, rod, rectangle, hollow bar, and wire, ensuring we meet diverse industry demands efficiently and reliably.
