Summary of knowledge points on metal bridge structure

1. Classification of metal bridge structures
A metal bridge is a support structure used for wiring and electrical equipment. It is usually made of steel material and has a long strip shape, divided into two types: groove type and ladder type. Its main advantages are corrosion resistance, fire resistance, high reliability, long service life, aesthetics, and easy maintenance.
2. Installation method of metal bridge frame
Metal cable trays can be divided into four types based on different installation methods: lifting, hanging, supporting, and wall mounted.
3. The purpose of metal cable trays
Metal cable trays are used in the following fields:
(1) Cross regional cabling and switching of telecommunications, networks, and computer systems.
(2) Wiring of low voltage and weak current equipment in factories and buildings.
(3) Wiring of lighting and fire control systems for high-rise buildings and parking lots.
(4) Wiring of lighting systems and fire control systems in large public places such as tunnels, subways, bridges, and airports.
(5) Can be used in places such as food and beverage manufacturing.
4. Materials for metal bridge frames
The manufacturing materials for metal cable trays are generally cold-rolled steel plates, stainless steel, or aluminum alloys. The surface treatment is generally hot-dip galvanizing or hot-dip galvanizing.
