Grates are flat, open structures made of metal or other materials, designed to allow liquids or small particles to pass through while blocking larger objects. They are commonly used in drainage systems, such as storm drains, to prevent debris from clogging pipes. Grates can also be found in kitchen sinks and barbecue grills, serving various practical purposes. In addition to their functional uses, grates can enhance safety by providing traction on slippery surfaces. They are often used in walkways and platforms to reduce the risk of slips and falls. Grates come in various sizes and designs, tailored to specific applications and environments.
