A filter plate subframe for a filter plate frame assembly having a filter plate frame and a filter plate subframe slidably receivable therein. The subframe comprises separate periphery segments attached to each other so as to form a continuous, generally rectangular periphery region with flank sides and end sides. The flank sides have a linear density lower than that of the end sides, and the end sides have a bending stiffness higher than that of the end flank, while either or both of the first end side and the second end side are provided with a reinforcement bar for increasing the bending stiffness said end sides. A supporting surface is provided on a first planar side of periphery segments forming the flank sides the supporting surface.
