Protective grates are safety devices designed to cover openings, such as drains or vents, to prevent accidents and injuries. They are commonly made from materials like metal or heavy-duty plastic and are used in various settings, including construction sites, public parks, and industrial facilities. These grates allow water or air to pass through while keeping people and objects safe from falling in. In addition to safety, protective grates help maintain cleanliness by preventing debris from entering drainage systems. They come in various sizes and designs to fit different applications, ensuring that they effectively serve their purpose while blending into the surrounding environment.
