FIELD: machine building.
SUBSTANCE: invention relates to machine building, particularly, to lattice devices, including three-dimensional ones. Decorative-applied article comprises vertically and horizontally and/or inclined elements and elements with curvilinear surfaces located, mainly, between them. Said elements are made mainly of pipe, and intersect and cross each other in the specified order. Said elements are interconnected, preferably, over the entire contact surface to make a flat/spatial geometrical figure with required consumer qualities. In the zone of connection of tubular elements to each other and/or to other elements of the item themselves elements and/or their ends are deformed with formation of transition zones from deformed sections to the main material so that form in cross section of deformation place profile, consisting of two C-shaped halves interconnected and facing each other with their inner parts or in the area of intersection of tubular elements between each other at least one, preferably, more elements are made consisting of at least two parts, after which intersecting elements are connected to each other by means of welding. Places of intersection of structural elements of the item are covered with decorative patch pieces.
EFFECT: invention can be used in production of decorative-applied products, including garden and park furniture, fences, grids, and so forth, from steel pipe using various methods.
