Grating is used to allow water and air to flow through sometimes but to stop large objects from passing through it. Grating is used in many places including drain covers, storm sewer covers, and swimming pools. Grating is made by grating manufacturers and grating manufacturing firms. Most grating companies make different kinds of grating that are used for different purposes and made out of different materials. Many grating companies make wire cloth grating, bar grating, in line grilles and grate struts. Many grating companies make steel grating, aluminum grating, fiberglass grating and plastic grating. Some grating companies make bridge decking and swimming pool grating while most make trench grating, sewer grating and drain grates. Some grating companies specialize in making grating out of one material, grating used for one purpose or one kind of grating.
