Perforated cable trays are used to safely hold and protect electrical wires. They are made from materials that resist rust, like mild steel, stainless steel, or aluminum. Some also have special coatings like zinc or epoxy to prevent corrosion.The type of metal used depends on where the tray is being installed (such as outdoor or indoor areas), how much protection is needed, and the cost.

Because of the holes in the tray, air can flow through easily, helping to keep the cables cool. These trays also offer some protection against dust and damage, making them a good, affordable choice for organizing and protecting cables
