Mesh (or mesh count) is the number of openings per linear inch, measured from the center of one wire to the center of the next. To determine mesh size, count the number of openings between the center of one wire and the center of a parallel wire one inch away. For coarse mesh, this can usually be done with a ruler. For finer meshes, a mesh counter or optical comparator may be required for accuracy. Mesh count does not account for wire diameter, which also affects opening size and... Read more

It is produced on automatic welding looms by accurately positioning the short (weft) wires over the long (warp) wires and spot welding their intersections (not over and under, as in ordinary...

A lift-gate is a device used to raise and lower items from ground level to the level of a tractor trailer. Freight companies deliver items on a tractor trailer which is approx 56 inches above the ground. These trailers are designed to load and unload at a loading dock or with a fork-lift. If your delivery location does not have a loading dock or fork-lift then you need a lift-gate. *Orders that are incorrectly processed with commercial address delivery to a location that does not meet the criteria for a commercial address as determined by the freight carrier will be subject to additional delivery...

It is a unit of length in the metric system. One micron is equivalent to 0.00003937 of one inch.

A square foot is a unit of measurement of area. A piece of material measuring 12 inches by 12 inches is one square foot. To compute the number of square feet in a piece of wire mesh you multiple its width in feet times its length in feet. For example, a piece of wire mesh 4 feet wide and 3 feet long would be 12 square feet. A linear foot is a unit of measurement of length. A piece of material measuring, for example 3 feet wide by 15 feet long would be 15 linear feet. The same piece of material could be described as 45 square feet; 3 feet wide x 15 linear feet which equals 45 square feet. Note: Sometimes the term "running foot is used to mean linear... Read more
