A grating is composed of a regularly spaced array of similar, parallel elongated elements. While most gratings are made from a single set of these elements, they can also incorporate two sets, with one set oriented perpendicular to the other. Gratings used over drains and air vents act as filters, blocking larger particles while permitting liquids to pass through. Abhyudaya Marketing Solutions is a top manufacturer of gratings in Hyderabad, and they also produce high-quality cable trays in Hyderabad.
