The SL55-11 is a StarModul cross joint (type +) for 5×5 cm square tube. It joins four tubes in a cross on the same plane. It is assembled with screws, without welding, and includes the Screws.
It is used where two beam lines cross, for example on flat roofs or structures with several modules. It is the no-flanges version in the 5×5 cm series, designed for exposed structures where the finish matters. See the 3D viewer on this page to view 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 galvanised steel tube (1.5 mm thickness); we can send it cut to size.
See also: all no-flanges joints for 5×5 cm tube and the 3D structure configurator, which calculates the joints and tubes for your project.
Yes. Each joint is supplied with its Screws.
No. The entire StarModul system is screwed, so it can be assembled and dismantled without welding.
In stock, 2–3 days in Catalonia and Aragon and 7–8 days in the rest of Spain. Out of stock, 2–3 weeks.

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.
