SEHNLI can supply complete waling systems to suit a variety of wall configurations. Waling usually comprises of two rolled steel channel sections placed back to back and spaced to allow the tie rods to pass between the channels. This spacing must allow for the diameter of the tie rod and the thickness of any protective material applied to the rod and take into account any additional space required if the tie rods are inclined and need to pass between the walings at an angle.
