Billet/Log Furnace

Granco Clark delivers the industries most efficient flame-impingement Aluminum Log/Billet Furnace. After all, we invented the flame-impingement furnace, the tunnel furnace, and the jet preheat furnace. well over 50 years ago. We set a new standard in the extrusion industry. That design has continued to evolve, most notably by the addition of an energy-saving “hot-jet” preheat section. It is still the fastest, most energy-efficient way to heat billets and logs. 

Hundreds of manufacturing plants around the world have GRANCO CLARK furnaces; some more than 30 years old and still on the job.
