What are metal corner straps used for in siding installation?

Metal corner straps play a crucial role in siding installation by securing corners during the installation process. When siding is applied to a structure, especially in areas that may experience movement or shifting, maintaining stability at the corners is essential. Metal corner straps are designed to reinforce these joints, ensuring that the siding remains firmly in place throughout the installation and for the long term thereafter.

While other aspects of siding can involve insulation and aesthetic considerations, the primary purpose of metal corner straps is related to the structural integrity of the installation. By using these straps, installers can help prevent any potential warping or separation of the siding at the corners, which could otherwise lead to moisture intrusion or damage over time. This protective function is vital to maintaining the overall durability of the siding system.
