What is Woven Wire Mesh?
| |
| Woven wire mesh is cloth made from wire strands. The wires that make up wire mesh run parallel to the width of the roll (cross wires) and parallel to the length (line wires). The cross and line wires are interwoven. That is, the wires cross over and under each other. Wire Mesh can be woven in a number of different styles depending on the material type, wire diameter, and opening size (see weave styles). Woven wire mesh is available in rolls, sheets or panels, and cut-to-size |

Weave Styles
| |
Weave style describes the way the wires cross over and under each other.
· Arch Crimp
· Sta-Smooth
Other types of weave are available by special order. |

Crimping
| |
Wires can be crimped to hold them in place or to add strength to the wire. A crimp is an indentation in the wire. Typically, both cross and line wires are crimped. Then, the crimped wires are woven into a cloth.
Weave and crimp are sometimes confused. Keep in mind that the way the wire is woven (i.e., the weave style) is independent of the crimp style. All woven wire mesh has a weave style. If a wire mesh is also crimped, it will have both a weave style and a crimp style. |

Wire Diameter
| |
| Wire diameter is a measure of the thickness of the wires in the wire mesh. Cross and line wires may be the same diameter, or cross or line wires may have a different diameter (typical in wire mesh used for filtration). When possible, please specify wire diameter in decimal inches rather than in wire gauge. |

Wire Spacing
| |
Wire spacing is a measure from the center of one wire to the center of the next. If the opening is rectangular, wire spacing will have two dimensions: one for the long side (length) and one for the short side (width) of the opening. For example, wire spacing = 1 inch (length) by 0.4 inch (width) opening.
Wire spacing, when expressed as the number of openings per lineal inch, is called mesh. |

Mesh
| |
Mesh is the number of openings per lineal inch. Mesh is always measured from the centers of the wires.
When mesh is greater than one (that is, the openings are greater than 1 inch), mesh is measured in inches. For example, a two-inch (2") mesh is two inches from center to center. Mesh is not the same as opening size.
The difference between 2 mesh and 2-inch mesh is illustrated in the examples in the right column. |

Open Area
| |
| Wire Mesh contains open spaces (holes) and material. Open area is the total area of the holes divided by the total area of the cloth and is expressed as a percent. In other words, open area describes how much of the wire mesh is open space. If the wire mesh has 60 percent open area, then 60 percent of the cloth is open space and 40 percent is material. |

Opening Size
| |
The opening size is measured from the inside edge of one wire to the inside edge of the next wire. For rectangular openings, both an opening length and width is required to define opening size.
Differences between opening size and mesh The difference between mesh and opening size is how they are measured. Mesh is measured from the centers of the wires while opening size is the clear opening between the wires. A two mesh cloth and a cloth with 1/2 inch (1/2") openings are similar. However, because mesh includes the wires in its measurement, two mesh cloth has smaller openings than a cloth with an opening size of a 1/2 inch. |

Rectangular Openings
| |
When specifying rectangular openings, you must specify the opening length, width, and the direction of the long way of the opening.
Opening Width
The opening width is the smallest side of the rectangular opening. In the example to the right, the opening width is 1/2 inch.
Opening Length
The opening length is the longest side of the rectangular opening. In the example to the right, the opening length is 3/4 inch.
Direction of Opening Length
Specify whether the opening length (the longest side of the opening) is parallel to the length or width of the sheet or roll. In the example shown to the right, the opening length is parallel to the length of the sheet. If direction is not important, indicate “None Specified.” |

Roll, Sheet, or Cut-to-Size
| |
| Wire Mesh comes in rolls, sheets, or the material may be cut to your specifications. The most common roll sizes are 36 or 48 inches x 100 feet: the most common sheet sizes are 36 or 48 inches x 120 inches. You can select from a variety of roll and sheet sizes from the stock list. |

|
Edge Type
| |
Stock rolls may have selvage edges. Sheets and cut-to-size pieces will be untrimmed. Any of the edge types defined below can be specified:
Untrimmed, Random Stubs - All stubs along one side of a piece are of equal length. However, the length of stubs on one side may be different than those on another side with the possibility that all four sides may have different length stubs.
Untrimmed, Balanced Stubs - The stubs along the length are of equal length and the stubs along the width are of equal length.
Channel Frame - (Special Order) Frames are “U” or “box-shaped” channels in which the ends of the wire are placed. Channel frames are used to frame the wire mesh enabling it to be mounted in an open space, such as an infill for a stairway. |

Length and Width
| |
| Length is the measure of the longest side of the roll, sheet, or cut piece. Width is the measure of the shortest side of the roll, sheet, or cut piece. All cut pieces are subject to shear tolerances. |

Quantity
| |
| Quantity is the number of rolls, sheets or panels, or cut-to-size pieces requested. Unless otherwise specified, the tolerance on quantity is “Exact Quantity". In other words, McNICHOLS will deliver the exact quantity you specify. |
