1.It is commonly used to support the cable pipelines such as communication pipeline and strong current pipeline, and also flue pipe and bridge in utility tunnel. 

2.The adoption of automated procedure of material preparation ensures the coincident sizes of upper main arm and lower main arm.

3.The main arm of corbel has continuous triangular tooth structure，fixing the  pipeline system by dedicated lock latch，to achieve a good impact resistance，anti-sliding and other properties as a whole.

4.The welding process of main arm and base plate strictly conforms to welding standard of GB 50661. The welding joint has high bearing capacity and stable quality. The wall thickness of main arm is no less than 2.5mm..

5.No welding need，just tightening the screws to fix the corbel

6.Corbel adopts hot-dip galvanization surface treatment. The coating thickness and quality conform to the provisions of standard GB/T 13912.
