MF39/1600 open seam anchor MF33 * 1.5 slit tube bolt 
 Pipe seam pipe seam anchor bolt slotted bolt rock friction stability 
 Main Specifications: MF45 MF43 MF40 MF39 MF33 
 Length: 1200MM-3600MM 

 Applicable to the permanent support of: coal, metallurgy, mining, railways, tunnels, water and electricity, culvert, highway tunnel, or temporary support. Slit tube anchor independent of environmental conditions applicable to coarse-grained sandstone and fine sandstone, siltstone, and a small amount of argillaceous 
 Sandstone rock roof. According to the geological conditions of surrounding rock, may be appropriate to increase or decrease the degree of bolt support network. 
 Anchoring principle: by a special process of cold roll forming. Will bolt into the rock, the use of the flexibility of the steel tube and the rock produced by friction on the surrounding rock anchoring, improve the strength of the rock mass, changing the surrounding rock stress state and stability of surrounding rock to achieve a total length of anchor Even in the rock mass deformation, displacement, and still maintain their anchorage performance.
