Are corrugated cable trays and molded cable trays the same?

Corrugated bridge and molded bridge are two different types of bridge, with different designs, uses, and manufacturing methods. Corrugated cable tray is a type of cable tray made of metal sheets, usually consisting of two or more metal sheets, each of which is bonded together by seals or glue. The characteristics of corrugated cable trays are high load-bearing capacity and good fire resistance, as their metal materials have good fire resistance. Corrugated cable trays are commonly used in power distribution systems in industries such as electricity, communication, and electronics. Molded bridge frame is a type of bridge frame made of metal molds, usually consisting of two or more metal molds, each of which is fixed together by bolts or nuts on the mold mating surface. Molded cable trays have high strength and rigidity, and are cost-effective, so they are widely used in power distribution systems in industries such as machinery, construction, and transportation. Structurally speaking, corrugated cable trays and molded cable trays are different. Corrugated cable trays are composed of multiple metal sheets, while molded cable trays are made from one or more metal molds. Therefore, in terms of load-bearing capacity and fire resistance, molded cable trays may be superior to corrugated cable trays. In addition, molded cable trays can be bent and processed as needed to meet specific installation requirements. When choosing between corrugated or molded cable trays, specific usage environments and requirements need to be considered. For example, if it needs to be used in high temperature environments or under heavy loads, corrugated cable trays may be more suitable. If it is necessary to protect cables or wires to a certain extent, molded cable trays may be more suitable. In short, corrugated cable trays and molded cable trays are two different types of cable trays, each with its own advantages and disadvantages, and need to be selected according to the actual situation.
