Product Introduction
Threaded rods is a hot-rolled solid bar with discontinuous external threads. It can be connected by coupler. When threaded rods are used in the field of anchoring, according to the requirements of the anti-corrosion grade, it can form different anti-corrosion systems with couplers, nuts, plates, corrugated pipes, smooth plastic pipes, end caps, and so on.
Application: Due to its high strength and flexible construction, threaded rod can be used as reinforcement cages, reinforcement beams, reinforcement meshes, soil nails, rock bolts, formwork tie rods, back pulls, micro piles, ground anchors and other structures. It is widely used in various construction scenarios such as building construction, dam reinforcement, slope support, tunnel support, hanging basket tensioning, and tower foundation. Usually used in conjunction with concrete, it has played a huge role in engineering construction.

Accessories information
Nut: When the threaded rod is applied in the support field, it is used to transfer the load of the plate to the anchorage section by tensioning and prestressing thread bar.
Plate: When the threaded rod is used in the support field, the component is in contact with the surrounding rock or soil and bears pressure from them.
Coupler: It is mainly used to connect threaded rods to reach the service length.
Plastic Centralizer: It is an element that can locate the rebar centrally and ensure the grout thickness and has various types such as lantern centralizer, strap centralizer, and so on.
① Strap Centralizer：It can be divided into internal strap centralizer and external strap centralizer. It comes with a strap and becomes cylindrical when rolled up. It is used with steel bars and plastic pipes, which ensures uniform grouting thickness. It has low-temperature resistance and corrosion resistance. Compared with the lantern type, it can be installed from anywhere, convenient and fast.
② Lantern Centralizer：During installation, insert steel bar in lantern centralizer to ensure uniform grouting thickness and good corrosion resistance.
