Stratified of reinforced plastic with fiber glass, in form of rectangular plates, characteristic color green-ocher, in different wide, long and thicknesses. Their reinforcements specially have been designed to grant extraordinary mechanical properties and one to them prolonged life utility. His calibrated elasticity and its enormous mechanical resistance they grant an efficient transmission of the vibration and an excellent performance to him. They are used to mount the screens in selecting grain machines and seeds, sort keys, calibradoras, densimétricas, descascarilladoras, etc. The main manufacturers and users of these machines use our crossbows.
