Another advantage is that the installed rack or machine can be modified, and profiles can be added at any position, which is a right-angle connection with strong adaptability. The disadvantage is that the installation process holes need to be drilled, and there is more preliminary preparation work.


  • The advantage of using corner fittings foraluminium profile corner joints is that there is no need to punch holes and no tapping. The aluminum profiles are directly cut according to the required length, and then fixed at right angles by right-angle connectors, bolts and nuts. This is convenient and fast. The disadvantage is that it affects the aesthetics, and can not install partitions, glass and other accessories.


  • If the angle groove connector is used for the right-angle connection of the aluminum profile, the advantage is that the connection is not only beautiful, but also convenient and fast.
