36U steel bracket material processing

Section steel is a kind of steel with a cross-section shaped like English letters. The cross-sectional shapes, geometric parameters and materials of the section steels produced in various countries are different. Currently, there are four main types of section steels produced in China:
Among them, He belongs to waist positioning and ear positioning. Due to its low carrying capacity, it is rarely produced.
The profiled steel supports must be reasonably calculated during design and should also be used reasonably in order to ensure safe production in mines and improve economic benefits.
Profile steel bracket, profile shed bracket, bow shed bracket, mining profile steel bracket
Profile steel bracket specifications Profile steel bracket, profile steel bracket, profile steel bracket
The main purpose of profile steel bracket is mainly used in mine tunnels and mine tunnels It is used for secondary support and support of mountain tunnels.
The application of profiled steel straight wall semi-circular arch support sheds in the mining of tunnel intersections has achieved remarkable results. The use of profiled steel retractable supports has better solved the problem of excavation support.

Compared with other rigid supports, the steel bracket has retractability and stable and reliable bearing capacity. It can adapt to the load and deformation of soft surrounding rock. It has high cross-section utilization rate, easy support and return of the bracket, small maintenance and recycling of the bracket. The reuse rate is high, the use of pit wood is reduced, and the environmental protection benefits are very obvious.
