 Uses: W is a new mine with a steel support and tunnel support material, the product can be combined with a variety of organized anchor bolt brackets, which can be distributed through multiple bolt join together to form a whole support structure significantly improve the overall effect of bolt in the roof rocks is incomplete, the best to deal with unstable rock. 
 W with the technical superiority of the steel (as compared with the flat strip) 
 1, W strip bending section modulus increased 37 times; 
 2, W strip rigidity increased by 70 times; 
 3, W cold-rolled steel with the hardening process, and improve the tensile strength of 12% -15%; 
 4, W and the surrounding dense steel with easy to paste; 
 5, W section steel with a high utilization rate, saving materials, low prices.
