The steel core in the plastic connector significantly strengthens the profile connection. These connectors are used in the construction of rack structures, stands, etc.
Couplers with a steel core and without a core can be combined, e.g. in a rack assembly - the upper shelf, where there is no such load, connectors with a metal core may not be needed, but cheaper plastic connectors without a core can be used.
Couplings with a steel core are very often used in the construction of aquarium walls due to their variability and strength.
