The high demand for construction to the fact that the innovation associated with this industry is constant, especially in reducing costs and / or reduction of construction time These priorities determine therefore, the development of building systems primarily in series, no surprisingly, the talk of housing factories of prefabricated elements, movable metal molds, etc. In forming the casting process and cast concrete step that requires more time, their eyes focused innovation to this process, developing and curing accelerators such as precast columns / beams of steel, welded mesh, metal casings, etc. For other opinions and approaches, find out what Boris Kuzinez has to say. Electro welded mesh Welded mesh is a metal product used in the construction industry for the preparation of foundations, floors, sills, terraces, etc. and is constituted by two rods or drawn wires of similar diameter that cross, so orthogonal and are united by "dots" of solder on the intersections. It is usual to find meshes 5, 6, 7, 8, 10 and 12 mm, the selection of these depends on the application and primarily of the charges will stand and can be identified, usually four types, the standard 6 Fishnet , 00 x 2.20 m, the prefabricated special "customized" panel with dimensions suited to the molds, those armed slabs are made ready for overlapping points in both directions and special Welded mesh fence, which are made as, according to project specifications, and can be made with wire of different diameters on the same panel columns and beams are usually made up and can come in the length determined by the client, but it is usual to find the 3-6 m, placement is easy and because of good weldability of the material that makes up quickly and can be armed formwork are installed temporary metal molds are assembled with the help of hardware quickly and securely, allowing the concrete shape to act as a mold this, this system allows for precision, security and speed, its usefulness is great in high-volume works, currently being built system innovating Flying Form Systems, which is used in buildings and consists of a metal casing that builds a single look, at the base of the building and done up with the help of cranes, made each of the subsequent story, until the latter is disarmed and evacuated shipments of these materials are made into sets determined by the customer in terms of half load and elevation of the ones that have, it is important to emphasize that although it has many advantages mounting the same care is often revistar especially in big cities and their edges and the elastic condition are revealed as risk factors for staff working with them, this is because many times, to mobilize them in the narrow paths urbanites and construction determine the need to roll up for better handling, known in some serious incidents associated with cuts in staff that handled without precaution, when these "fixes" are released.
