A woven screen can include at least one first fiber oriented in a main direction of the woven screen and having a polymer coating and a first stiffness value, and at least one second fiber oriented in a direction of the woven screen different from the main direction, configured to intersect with the at least one first fiber, and having a modified polymer coating and a second stiffness value about 20% to about 70% greater than the first stiffness value. The modified polymer coating can include a polymer, a crosslinking agent, a catalyst, and a free radical initiator. The at least one first fiber can include the warp and the at least one second fiber can include the weft, respectively, of the woven screen. The second stiffness value can be about 40% greater than the first stiffness value over a temperature range of about −40° Celsius to about +40° Celsius.
