Are C-shaped steel or angle steel used for pipe gallery support and underground pipe gallery power support?

The underground pipe gallery support is determined according to the design drawings, and the professional pipe gallery support, that is, the finished pipe gallery support, is designed and used most frequently, and C-shaped grooves are prefabricated. Generally, the C-beam is 4 1*4 1, the maximum, and the steel plate thickness is 2.0 or 2.5, depending on the drawing requirements. C-beam pipe gallery bracket has the characteristics of high strength, light weight and convenient installation.

The pipe gallery bracket is also made of angle steel. Generally, angle steel or channel steel is used as the column, and angle steel is used as the support. This should also be welded in advance. Generally, 63 channel steel is used for columns and 50 angle steel for supports. National standard materials must be used.

According to the bearing capacity, the bearing capacity of angle steel channel is larger, generally 5mm or 6mm thick. Its own weight is also large, and the cost is also high.
