All the firebowls are made from 4mm steel plate which results in a firebowl which will last many years and will not rust through after one summer of use. There are two sizes as standard, small which is 660mm diameter corner to corner, and a larger one which is 880mm diameter corner to corner. They are hexagonal in shape as standard, but it is possible to make other sizes and shapes to order. All firebowls are painted with several coats of high temperature paint in matt black finish. There are also cooking tripods available to go with the firebowls which are ideal for hanging a dutch oven or any other cooking pot to complete the outdoor cooking experience.
