Perforated Sheets
As consumers, we are not given to wonder much about the work that holes do for us. But, for the
product designer, holes in sheet metal can provide the perfect solution to a multi-faceted design
problem. Being a hub for filtration solutions meshes and perforated sheets are abundantly used. We
can provide perforated sheets of varied patterns depending upon holes size and open area required.
Below mentioned patterns are readily available with us.

Meshes play a vital role in filtration.
Here are a few FAQ’s regarding meshes.
What does mesh size mean?
Figuring out mesh sizes is simple. All you do is count the number of openings in one inch of screen (in the United States, anyway.) The number of openings is the mesh size. So a 4-mesh screen means there are four little squares across one linear inch of screen. As the number describing the mesh size increases, the size of the particles decreases. Higher numbers equal finer material. Mesh size is not a precise measurement of particle size.
What is a micron?
A micron is another measurement of particle size. A micron is one-millionth of a meter or one twenty-five thousandth of an inch.
How fine do screens get?
That depends on the wire thickness. If you think about it, the finer the weave, the closer the wires get together, eventually leaving no space between them at all. For this reason, beyond 325-mesh particle size is usually described in “microns.”
What do the minus (-) and plus (+) plus signs mean when describing mesh sizes?
Here’s a simple example of how they work. –200-mesh would mean that all particles smaller than 200-mesh would pass through. +200 mesh means that all the particles 200-mesh or larger are retained.
