Steel frame screens are mostly applied to the shale shakers with wedge fastening equipment. The screen frames adopt that high-strength square steel tube welded to multi-ribbed construction. They are sturdy and reliable. These screens are constructed with two or three stainless steel layers bonded to a steel support plank. Accessory rubber plugs may be used to repair rips or tears. By doing this, we can cut down time and reduce the production costs. We can supply steel frame screens with mesh sizes ranging from 20 to 250.
