The 0055-05 is a StarModul T-joint for 5×5 cm square tubing. It connects an intermediate post with a continuous horizontal beam, forming a T. It is screw-mounted, without welding, and includes the necessary hardware.
It is used in posts that are not at the corners, along the sides of the structure. This is the most common size for pergolas, porches, gazebos, and light self-assembly structures. View the 3D viewer on this product page to see the exact shape of the part.
Fit the tubes into the part, check the corner bracket, and screw them in. No welding or special machinery is needed, so the structure can be assembled directly on site. For this joint, you need 5×5 cm (1.5 mm thick) galvanized steel tubing; we can send it cut to size.
This part is included in: Structure – 3 x 3 Meters – 1 Slope – Posts (5×5 cm Tubing), Porch – 3 x 3 Meters – 1 Slope – Posts (5×5 Tubing), Structure – 3 x 3 Meters – 0 Slope – Posts (5×5 cm Tubing), Structure – 6 x 3 Meters – 2 Slopes – Posts (5×5 cm Tubing).

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.
