The coupling for pipe-work metal structures consists of suitably shaped rolled steel sheet connected with metal pipes with a circular cross section (1), (5) via a node (3) made of cast aluminium.This coupling method does not require welding since connection is achieved by suitably shaping the connected parts (1), (3), (5) and with the use of screws (2).The coupling-node for pipe-work metal structures (3) can be used to construct pipe-work metal frames which are intended for supporting surfaces.
