▲ The table data is applicable for: correct installation, no margin or distance influence, minimum substrate thickness. The table data is based on C25 substrate concrete, and if the substrate grade changes, the concrete strength influence coefficient should be added according to the specifications.

▲ The above table does not include any products. Please refer to the bearing capacity calculation methods in the "Technical Specification for Rear Anchoring of Concrete Structures" JGJ145-2013 and "Mechanical Anchors for Concrete" JG/T-2017 to verify and obtain the corresponding data. For specific details, please consult the Technical Department of Nanjing Telesun S&T Industry Co., Ltd
