They are applied for performing corners and angles of concrete struters where panels united to each other with a specific angle.
Outer corners : as the name implies this kind of corner is used to connect two modular forms that cover the cover the outer surface of the concrete. dimensions of these angles are measured usually (5*5)(10*5)(10*10) which are manufactured in heights of 100.150.&200cm.
Inner corners: this kind of corner is used to connect two crossing modular forms that cover the concrete form inside. Inner corners are basically designed for concrete inside formwork and are mostly used for connecting slabs to beam drops or inside corners of the walls. The angle corners are 90 degrees dimensions of these corners are follows.
