Conform to CEI EN 61537. DKC mesh trays are manufactured with the help of an advanced technology, in fact the structure design provides for buttwelding of the upper longitudinal wire (so called T-welding). This kind of structure guarantees the maximum safety for assemblers, also excluding the risk to damage cables while laying, avoiding contacts with sharp ends of the metal wire of conventional trays. A particular structure of sides with reinforcement ribs guarantees a high longitudinal resistance.
