ABSTRACT:
A grid structure and screen device including the grid structure are provided for a vibrating shaker for filtering solids out of a moving fluid stream passing across this screen device. The grid structure has openings defined by intersecting lines of substantially continuous solid grid lines forming an angle. The angle formed at the intersection being from between less than 90.degree. and more than 0.degree., such that the grid structure fatigued resistance is enhanced while providing maximum open area therethrough.
