Many people can't tell if the cable tray is the same as the metal trunking?

In fact, it is different. Cable trays are mainly used to lay cable lines, while metal trunks are mainly used for laying wire wires. The materials of the two are also different. The material used for the bridge is cold-rolled steel, while the wire trough is made of hot-rolled steel.

Cold-rolled sheet: It is processed by hot-rolled sheet. Generally speaking, the cold-rolled sheet is an upgraded version of the hot-rolled sheet. In comparison, the thickness and hardness of the cold-rolled sheet are stronger than that of the hot-rolled sheet, and it is not easily deformed. The appearance will be smoother and more beautiful.

Hot-rolled sheet: compared with cold-rolled sheet, the thickness, hardness and so on are not far from the cold-rolled sheet, and it is easy to deform and other defects. It is not suitable for carrying high-weight items, but it is easy to process, so most of them are used. In processing evolution.

First, what is the bridge?

(1) There are various types and materials of cable trays.

Models: trough, tray, ladder, split, combined, large span and many more. (They all have different advantages, depending on the construction environment.)

Surface treatment: electro-galvanized "cold galvanizing", electrostatic spray, fire-retardant paint, hot-dip galvanizing, also known as "hot-dip galvanizing", plating

Two: What is the trunking?

There is only one type of metal wire trough, which is a trough type groove, sealed type, and is made of hot rolled sheet. It is more than enough for the load wire.

The metal wire trough is the same shape as the trough cable tray, except that the metal wire trough is slightly smaller in size and has a different material performance.
