    ● The values are suitable for: correct installation, no influence of spacing and edge distance, minimum base material thickness.

    ● All the data applies in C20/25 concrete base material. If the base material grade changes, the corresponding concrete influence coefficient will needs to be increased. 

    ● The * part in the table is steel failure control.

    ● The material of all the anchors in the table is alloy steel, grade 8.8.

    ● Design load: including material partial factor, but not including overall partial factor.

    ● Recommended load: including not only material partial factor, but also including overall partial factor 1.4.

    ● If your NJMKT Dismountable Anchor(Mechanical Anchors) with special material and specification is not listed in this table, please contact our engineer for advice.

    ● All basic anchor data in this table is given according to 2013 ETAG001 and Appendix. The partial factor in the load application must be in accordance with national regulation.
