Product Description

Introduction Of U29 Mining Support U Steel Support

29U Mining Support U Steel Support is mainly used for mine tunnel, mine tunnel secondary support, as well as support through the mountain tunnel support purposes. 29U shaped steel support lift straight wall semi-arched shed in the Ready Roadway Intersection of applications, and achieved remarkable results. Optional retractable U-shaped steel support, solves the problem of tunneling support.
Advantages
29U steel support has the characteristics of withstanding high pressure, support long time, easy to install and easy to deformation. 29U shaped steel support lift straight wall semi-arched shed in the Ready Roadway Intersection of applications, and achieved remarkable results. Optional retractable U-shaped steel bracket, solves the problem of tunneling support. 29U shaped steel support than other rigid support with a scalable and reliable carrying capacity to adapt to the load and deformation of soft rock, cross utilization, branch back to the convenient stand, bracket, reuse rate, reduce prop use, environmental benefits very obvious.
Technology Parameter
Tensile strength(TS)larger than 575MPa,
Yield strength(YS) larger than 400MPa,
EL elongation greater than or equal 26%
