Product Introduction

20Mnk U steel arches , U shape beam support , U channel steel arches 

U steel beam arch is form by bending U steel,there are U18 U25 U29 U36 four models of U steel .

U shaped steel arch with a high setting load ,support strength,easy to install ,easy deformation,monly used in the manufacture of roadway retractable metal arch , as mine tunnel ,mine tunnel secondary support ,and the support of the branch tunnel though a mountain protection and other purposes .

U steel support structures :

1 The top beam

Arch arched roof beams ,the number depending on the size of the roadway,frame by force , different conditions of carriage have one or several top beams .

2, The post legs

There are three kinds of leg post forms ,one cap ,two post legs ,with two base steel .

3, Connections

Connector is a holding device between one section of to another section can play a role in the connection section between two steel can also be connected to the joint portion of the pressing ,preload, having friction between the U-shaped steel ,thus ensuring arch support has some work and a certain resistance to shrinkage .

4,Steel tie rod 

Between the rod holder is to enhance the rold of the relative stability of hte overall arch ,the arches from the longitudinal coupled together to form a whole .

5,The backing material .

The backing material is a filling material U shaped steel arch and wall rock between the aim is to make the U shape steel arch and rock in close contact, to improve the situation by force arch to improve its carrying capacity and maintain the stability of the surrounding rock .

U shaped steel arches Features

1,U shaped steel bracket to with stand pressure, supporting a long time ,are easy to install easy deformation characteristics .

2,U shape steel support with a scalable and reliable carrying capacity than other rigid support, adapt soft rock load and deformation .

3,U shape steel arch section utilization ,convenient support arch back , small amount of maintenance .

4,U steel support recycling reuse rate ,reduce prop use, environmental benefits are clear .
