A screen assembly features a support structure 602 and at least one layer of screening material 601 thereon, wherein the support structure 602 features structural members 605,606 having a thermal expansion coefficient and the at least one layer of screening material 601 has a thermal expansion coefficient. The thermal expansion coefficient of the structural members 605,606 is substantially equal to the thermal expansion coefficient of the at least one layer of screening material 601.The invention also provides a method for making a support structure for a screen assembly, the method comprising the steps of placing at least one support member 605,606 in a mould 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 617. |
