Metal structures are considered higher quality than plastic boxes for electrical wiring. For their manufacture, manufacturers use two types of material: galvanized steel and anodized aluminum. Such products are able to withstand heavy loads.
Products made of galvanized steel have refractory properties. They are used for installation of warning systems and video surveillance. Steel boxes protect wires from mechanical damage and the effects of electromagnetic radiation. The price of these products is much higher than plastic. The cost of a galvanized cable channel 60×40 mm with a length of 2 m (manufacturer of OBO Bettermann) is 1175 rubles / pcs.
Boxes made of anodized aluminum do not transmit electromagnetic radiation to the wiring. This type of material is resistant to fire and mechanical stress, it is practical and durable. The purchase of an aluminum mini-channel 65×40 mm per section (manufacturer SIMON) will cost 3500 rubles / piece.
