This material is pultruded product and has uniform composition (unidirectional reinforcement) throughout.
It is suggested that care is exercised when cutting this hollow material.
Use only very fine tooth hand saws of thin fine files for cutting and shaping this material to length.
Do not use excessive clamping pressure when holding in a vice. Although the material is exceptionally strong longitudinally, crushing pressure exerted by a vice can cause deformation. Additionally to maintain surface integrity use only soft jaws when holding in any vice or clamp.
