Sombrero 1 is a round metal hearth. It was made of 4mm thick corten steel. The hearth made of Corten steel is very durable and requires no maintenance. The only thing we have to do is to clean the firewood from fuel residues. Corten hearth combines attractive design and practical application. Works great as a light and heat source on cooler days. The corten hearth will work in the garden or in the backyard terrace.
