Our oak beam fireplace mantels are made to order. As these are created from a natural product, each piece will be different. The mantels are made from dried pieces of oak, so they will contain surface cracks, splits and knots. There may also be one or two waney edges. Following lengths below are available in section sizes - 100x75; 125x125; 150x150; 200x50; 125x100; 200x125; and 225x125. Can also be cut to custom size using our custom cutting calculator. Our mantels are available in a rough sawn finish, or a planed all round finish. These oak beam mantel pieces for fireplace surrounds are created from partially dried new untreated oak sleepers. They are left untreated so that you can finish with your own favourite colour - by using either an oil, stain, or wax. We do supply a range of Treatex Hard Wax Oils which are available in a selection of colour tones and sizes - you will also find these on our website.
