The beam is made using cross grain laminated wood construction. This gives the beam its strength and prevents warping or twisting. No center support is needed. The core is planed and sanded to the competition oval beam shape. Our beams are built as close as possible to competition beams for a realistic training experience. This includes the padding, covering and shape. The padding is closed cell polyethylene foam. The same padding that is used on competition beams. It is covered with a heavy grade synthetic suede material. The material is durable and easy to clean. The work surface is 4 in. wide and the beam is 7 in high. The support braces are 12 in. wide and made of steel. The beam core is pre-drilled for our metal beam legs which can be added at a later date. This will make a great practice beam.
