About Granco Clark

Founded in 1947, Granco Clark is the leading North American supplier of equipment to the aluminum extrusion industry.

In 1954, we introduced the first direct-flame impingement furnace to the industry. Though our design has evolved considerably, a Granco Clark furnace is still the fastest, most efficient way to heat billets.

We've followed up that first key innovation with many others that have enhanced productivity, reduced labor needs, and boosted profile quality—from the first computer-controlled system to synchronize the entire extrusion process to our triple-patented Taper Quench, an economical way to achieve isothermal extrusion.

We back our technological innovations with a strong commitment to quality. Granco Clark is currently the only ISO-9001 certified manufacturer of extrusion equipment.

Granco Clark is a member of the Aluminum Extruders Council.
