The electro-welded grating or electroforged grating is a grating whose metal elements have been linked through electric welding, forming a single lattice body, with a mesh structure, the result of the union of all its parts.

The electrowelded grating is a metal piece composed of several equal strips of strapping (bearing plates), placed in parallel and on edge, and separated from each other, which have rods with a diameter greater than their thickness welded perpendicularly, at all their crosses or intersections.

The electrowelded grille is made up of three elements:

The manufacturing procedure for the “electro-welded” gratings stands out for the particular system that joins the supporting plates with the transverse rods, by means of fusion welding, without adding material, forming with said union a single body.

The heat necessary to carry out welding at the fusion temperature is obtained by means of electrical energy, and by pressure, the penetration of the transverse rods with the supporting plates is achieved.

Due to its particular manufacturing system, it accepts cuts and shapes without danger of it falling apart. The closing frame in the cuts and shapes is made with a plate with the same characteristics as the supporting plate using MIG welding.

The final finish of the electrowelded grating, made of hot-rolled strip, is usually galvanized by immersion in molten zinc. This finish gives the grating surface protection against external corrosive agents.

The electrowelded grating is designed to work flat, with uniformly distributed loads or with punctual loads (loads concentrated in small contact areas), as long as it has a continuous metal support where all the supporting plates rest.

The calculation standards to define the loads that the grid can support are those contemplated by the Technical Building Code, as well as by Eurocode 3 (a set of European standards that includes the rules and principles for the calculation of steel structures).

The electrowelded grating is a product of great resistance and lightness that is usually found in floors and corridors of industrial work (oil platforms, power plants, vehicle warehouses, emergency exits, etc.) and in civil works (stairs, fences, tree pits, gutters, facades, false ceilings, bars, protection bars, fences, enclosures, etc.).
