Materials of Construction & Wire Diameter

When selecting a screen, end users should pay special attention to the screen design and the size of the opening. Most manufacturers focus on the frame structure and shaker fastening applications. However, focusing on a multilayered, wire cloth formula and wire diameter is critical. One manufacturer’s bottom layer of screens is comprised of thicker, market-grade wire. This yields a stronger base, which allows the other layers to maximize performance during the most severe conditions. These screens are made of materials including 304 stainless steel, woven wire cloth, 12-gauge perforated punch plate and a one-inch steel tubing frame. These materials help increase the shaker screen’s durability. One manufacturer developed a line
of polyester-powder-coated screens.
This special powder coating is based on
a polyester resin for improved mechanical bonding and enhance mechanical properties when compared to polyester alone. This careful blend of additives allows for a higher level of cross-linking of the resin binder, which ultimately produces a harder and more durable coating.
