W Straps are commonly used when additional support is required in conjunction with Roof bolts. These steel straps are pulled into the coal surface by the bolts and tend to con? rm to major irregularities in the coal.
W Straps provide a large surface con? nement to any loose coal that may form between installed Roof bolts.
Standard W Strap lengths range from 2400 to 4000 mm in 300 mm increments.
Non-standard designs are available against customer's requirement.
