The SL55-05 is a StarModul T-joint for 5×5 cm square tubing. It joins an intermediate post with a continuous horizontal beam, forming a T. It is screw-mounted, without welding, and includes the screws.
It is used on posts that are not at the corners, along the sides of the structure. It is the version without flanges of the 5×5 cm series, designed for exposed structures where the finish is important. See the 3D viewer on this page to see the exact shape of the part.
Fit the tubes into the part, check the corner bracket, and screw. No welding or special machinery is needed, so the structure is assembled directly on-site. For this joint, you need 5×5 cm galvanized steel tubing (1.5 mm thick); we can send it to you cut to size.

With the StarModul 3D steel structure configurator, you can define the dimensions, geometry, and initial configuration of a structure using our bolted connection system.
The tool generates a preliminary list of the necessary joints, a quantity takeoff for pipes and profiles, and an initial assessment of the configured components.
