Cable trays are used in electrical wiring of buildings to support insulated electric cables for power distribution, control and communication, and most commercial and industrial projects use cable trays as an alternative to electrical steel pipes because Cable trays with high strength protect cables from external factors and help to expand, stabilize and restore cable transmission lines.\r\n\r\n[Standard electrical galvanized cable tray](https://navasan.ir/?page_id=314) is used as an alternative to open wiring and is a cost-effective solution because of their user-friendly design in building structures. Such as parking lots, hospitals, tunnels, and elevators, they are widely used for carrying and guiding electrical wires and cables because unexpected new cables can be added inside the cable tray.\r\n\r\nAccording to international standards, cable trays are a unit or a collection of units or sections and related fittings that form a rigid structural system used to secure or support cables in cable management systems.

One of the most important steps in the implementation of flower boxes, fountains and roof gardens is sealing the roof. The best and most reliable way to prevent water and moisture from entering the insulation structure is fiberglass or FRP, which includes one or two strong but flexible layers. It is of the relevant material, which does not damage the structure or insulation under different weather conditions and physical or thermal movements, and is a very safe method due to its indestructibility after complete drying. Another advantage of this type of insulation for the implementation of green spaces is its anti-fungal and anti-plant properties, which is very important for planting seedlings and various plants.
