A bridge is a structure used to support and protect cables, wires or pipes. It is usually made of metal or plastic, with beams and support feet, and can be suspended from the wall, ceiling or floor. Two common types of cable support systems are ladder bridges and channel bridges, which are distinctly different in structure and function.

First of all, ladder type bridge is composed of cross beams and longitudinal beams, similar in shape to a ladder. The cross beams are usually flat and straight, while the longitudinal beams are support rods perpendicular to the cross beams. This structure allows ladder bridges to provide high load carrying capacity and stability for larger scale cable routing. In addition, ladder bridges can be adjusted and expanded as needed to accommodate a variety of cabling requirements.

In contrast, channel bridges are made up of a series of parallel channels. These slots are usually fixed to brackets that form a flat surface for cable installation. Slot bridges are simple and compact, making them suitable for smaller scale cable routing. They are usually used for shorter distances of cabling in places such as offices, stores and houses.

In addition, ladder bridges and channel bridges differ in terms of installation and maintenance. Ladder bridges are relatively complex to install, requiring precise connections and fixings between cross and longitudinal beams. Channel bridges are relatively simple to install, requiring only the channel to be placed on the bracket. In terms of maintenance, ladder bridges require regular inspection and adjustment of the connecting parts, while channel bridges require relatively little maintenance.
