Gratings are made of parallel, perpendicular metal or non-metal bars or plates that are arranged in a grid-like pattern. They can be used as flooring, stair treads, catwalks, and drainage covers, among many other things. Additionally, they can be used as security barriers and as decorative elements on building facades. Gratings are frequently used in commercial and industrial settings, as well as in open areas like walkways and sidewalks. Depending on the application and particular requirements, they come in a variety of sizes, shapes, and patterns.
