A screen assembly for a shale shaker, the screen assembly including a support structure and at least one layer of screening material thereon. The support structure includes structural members having a thermal expansion coefficient and the at least one layer of screening material has a thermal expansion coefficient. The thermal expansion coefficient of the structural members is substantially equal to the thermal expansion coefficient of the at least one layer of screening material. A method for making a support structure for a screen assembly is also provided. The method includes placing at least one support member in a mold whereupon a flowable plastics material is injected into the mould, whereupon the flowable plastics material hardens, at least a portion of the flowable plastics material forming a brace. |
