With the range of corner connectors, you can connect tubes without welding. The square tube connectors for square tubes differ in two versions. For light loads, choose the more affordable polyamide plug connectors without a steel core. If you want to achieve higher load capacities for your construction, order the extra stable connectors with a steel core. These can withstand a compressive load of up to 400 kg per connector pin.
