Corner, T and cross connectors – differences and areas of application

Aluminum profiles can be assembled stably and flexibly using the appropriate connectors. Corner connectors, T-connectors, and cross connectors are particularly common. Each variant has specific advantages that should be considered during the planning phase.

Corner connectors

Corner connectors are the standard solution when two profiles are joined at right angles. They ensure high stability and are used in both mechanical engineering and DIY projects. Typical examples from the product range are the 30 mm corner bracket with 8 mm slot or the automatic double connector with 8 mm slot , which reliably create stable frames and housings.

T-connector

T-connectors join three profiles in the shape of a "T". They are used when a crossbar is connected to a main profile, for example in shelves, workbenches, or racks. A suitable example is the central connector with groove 8 , which is also suitable for higher loads in industrial applications.

Cross connectors

Cross connectors join four profiles in one plane. They are ideal when several profiles need to be joined at a single point. This creates stable substructures, such as those used in machine frames or shelving systems. A classic example is the 40x40 cube connector , which is available in various versions in our shop.

Conclusion

Whether corner brackets, central connectors, or cube connectors – each connector type has its typical applications. Corner connectors secure frame constructions, T-connectors create connections between cross and main profiles, and cross connectors form stable nodes. Spannwerk offers these products for both private projects and industrial applications. Thanks to our cutting service and fast delivery within three days, projects can be implemented without delay.
