Figuring out the mesh number is simple. All you do is count the number of openings in one linear inch of screen. This count is the mesh number. A 4-mesh screen means there are four little square openings across one inch of screen.

Mesh (Mesh Count) — first, measure 1″ (from center to wire to center of wire), then count the number of openings in that 1″ span. This number is your mesh, or mesh count. If you require a space cloth, what is the clear opening (in inches) between parallel and adjacent wires?

1.1 This standard covers requirements for welded steel wire fabric for general use, such as fencing, window grill and crates. 1.2 This standard is not intended to cover welded wire fabric for concrete reinforcement (see IS 1566).

Sieving or screening is a method of categorizing a powder’s particle size by running the powder through a specific sized screen. A -6 mesh powder has particles that measure less than 3360 microns. A powder that is -325 mesh has particles that measure less than 44 micron.

The standard window screen mesh is 18-by-16 and made out of fiberglass or aluminum. Patio, porch or pool side screens have a mesh size of 18-by-14. The smallest sized mesh is 20-by-20; the tightly woven mesh allows for ventilation while still keeping out tiny insects.

A mesh size of 1.2mm X 1.2mm is large enough for air circulation, but small enough to keep mosquitoes out. For effective malaria protection, the recommended mesh size is 120-200 holes per square per inch. Nets made of polyester or polyamide are the most lightweight and longest lasting.

Mesh is a count of the number of evenly spaced openings in one square inch of a screen (i.e., screen size). Mesh is basically a specific size or dimension (see Mesh and Micron). Grit is generally defined as an angular media used to abrade or cut a work piece. Grit is a specified range of particles for a given product.

18×14 Mesh Pool, Patio and Porch Screen is stronger than standard window and door screen, making it the ideal screen for large openings such as screen porches, and patio and pool enclosures. Designed for applicataions where extra strength is desirable.

The Best Screen Material: Fiberglass vs. Aluminum. Fiberglass and aluminum are the two main choices for a screen material that helps protect against bugs. The holes in both types of screens are small enough to keep insects out, but for most projects, fiberglass is the best choice.

MESH, MESH COUNT To determine mesh or mesh count, start from the center of one wire and count the number of openings to a point exactly one linear inch away. 20 mesh (or 20 x 20 mesh) indicates that in one linear inch, there are twenty (20) openings.

Aluminum screen is more rigid than fiberglass and thus a little harder to install, but it’s also more durable, although it is prone to creasing during installation and to denting at any time. In coastal areas, aluminum will oxidize. Available in gray, black, and charcoal; black usually offers the best visibility.

A normal screen that is primarily in shade, remains relatively dry, gets cleaned semi-regularly and is not subject to lots of handling (except at window cleaning time) should last you 10 to 15 years before it begins to break down and need replacement.

Aluminum Wire Window Screen is a Strong and durable insect screening that resists rust and will not sag. A protective finish prevents corrosion and strengthens the weave. Charcoal and Black aluminum screen finish reduce glare for greater outward visibility.

Pet Screen is made from vinyl coated polyester. It is much stronger than traditional fiberglass or aluminum screening. Pet Screen is 7 times stronger than traditional screen mesh. Pet Screen is available in Black and Gray.

Pet screens are designed with the destructive potential of pets in mind. The materials used are strong and resistant to the claws of a cat or the brute strength of a dog. If you have a dog or cat, it’s vital to invest in pet screen for your pool or patio enclosure.

Aluminum – more durable than other materials, aluminum screens can unfortunately dent and crease easily. Stainless steel – stronger than aluminum, stainless steel fly screens are recommended for homes in bushfire areas.
