Bolt type crack reliable anchor bolt BZ+

Product Introduction：

Product No.: bolt type crack reliable anchor bolt BZ+

Bolt type crack is reliable. Anchor bolt BZ + has the advantages of high bearing capacity, small spacing and edge distance. The surface of expansion vertebrae is protected by special materials with heat resistance and corrosion resistance, which ensures the necessary subsequent expansion when cracks occur in concrete. It can be installed alternately, which is simple and convenient, and does not need special hole rotation and installation tools.
