Screens and Netting

Screens and netting consists of a surface with openings of specific sizes. Screens, sieves or similar products are made by perforating a sheet, weaving metal wire or synthetic fibers or electroforming. Screens and netting are also used to provide open but secure barriers against flying objects or debris or insects.

Screens and netting can vary from extremely fine mesh to more industrial strength materials. Industrial screens and netting are used to provide a protective barrier, such as fences at construction sites or on sports fields. Industrial screen or industrial netting can also be used underneath bridges or around buildings to catch falling debris. Containment or cargo netting is used on trucks to protect and contain loads during transport.

Screens and netting made of wire mesh are commonly used in windows to allow for airflow while keeping insects and other pests out. Wire mesh screens are specified for particular uses based on the percentage of open or screened area. Wire mesh screens and netting come with different weaves and may use different gauges of wire. Heavy duty screens and netting can be used as a grate or grid, which may provide flooring on stairways or catwalks, or as security grates over open floor vents or drains.

Other screens and netting are used as a sieve or strainer in bulk goods processing, dewatering, water treatment, food processing, and other processes that require straining or sorting. A sieve or strainer is used to separate components or materials of different sizes. A series of strainers or sieves may be used in conjunction to offer refined filtering or separating. In applications such as dewatering, sieves and strainers are used to wash solids with water, and may also be connected to motors that vibrate or shake the screens.
