Metalized mesh for architectural constructions with a coating and method of producing such mesh through projection welding

摘要

A metalized grid (S) for architectural structures and a method of manufacturing such grid (S) are described. The metalized grid (S) consists of front rods (1) and supporting rods (2) crossing one another, the grid (S) being made by joining the front rods (1) with the supporting rods (2) by projection welding, the front rods (1) and the supporting rods (2) being made of metalized carbon steel with a metallic coating, each front rod (1) and each supporting rod (2) having a continuous longitudinal projection constituting a welding projection, and at least the welding projections of the front rods (1) comprise at their welding site an accumulated mass of the metallic coating which is bigger than the mass of the coating on the remaining surface of the front rod (1), the accumulated mass of the coating actively forming a shield for the weld during joining the front rods (1) with the supporting rods (2) by projection welding.
