Design: The square flange typically has four holes for bolts, arranged in a square pattern. These holes align with corresponding holes in the mating flange or surface to create a secure connection.

Materials: Square flanges can be made from various materials such as steel, stainless steel, aluminum, or plastic, depending on the application and environmental conditions.

Applications: They are often used in applications where a rigid, stable connection is needed, such as in piping systems, machinery, or structural assemblies.

Standards: Flanges come in different sizes and specifications, so it’s important to ensure that the square flange matches the dimensions and standards required for your particular application.
