An angle bracket is a type of hardware used to reinforce or support structures at right angles. It consists of two perpendicular plates or brackets that are joined together to form an L-shape. The plates are typically made of metal and may be coated with a protective finish to resist corrosion. Angle brackets are commonly used in construction to provide support for beams, joists, and other load-bearing structures. They can also be used to join together two pieces of wood or metal at a right angle. Angle brackets come in a variety of sizes and thicknesses to suit different applications. They may be fastened to a structure using screws, nails, or bolts, and may be used in conjunction with other types of hardware such as washers and nuts for added strength and stability.
