Our hollow bar for self-drilling anchor systems has been tested by SGS-CSTC Standards Technical Services Co., Ltd. Nanjing Branch, one of the internationally recognized testing and inspection organizations.
The SGS test report, No. NJIN2511002861ML03_EN, dated November 19, 2025, covers a Hollow Bar with specification SDR51/34-500-400-W6.80 and material grade Q355B. The tested product was subjected to a tensile test to evaluate its mechanical performance.
According to the test results, the tested hollow bar achieved a tensile strength (Rm) of 632 MPa, a 0.2% proof strength (Rp0.2) of 548 MPa, and a total elongation at maximum force (Agt) of 9.5%. The elongation after fracture was also recorded at different gauge lengths.
This independent third-party testing provides customers with objective technical data for evaluating the strength and mechanical performance of our self-drilling anchor hollow bars. It also demonstrates our commitment to consistent product quality, reliable manufacturing, and quality verification through independent testing.
