The square metal table tops are for the Halo Firepit. They are constructed out of noncorrosive aluminium and stainless steel. It is safe to leave the table top outdoors in the elements. The aluminium is hard anodised to create a scratch resistant surface that is integral to the aluminium itself. This surface is hard, but may be susceptible to scratching from fine grit particles drawn across the surface.
Please use a clean damp cloth to wipe down. For more information on product characteristics please see care instructions included with product.
