China Testing & Certification International Group Co., Ltd. (CTC, Stock Code 603060) originated from the testing and certification business of China Building Materials Academy in the 1950s. After 70 years of unremitting efforts and persistent pursuit, the company has formed five business categories: detection and testing, certification and evaluation, testing instruments and intelligent manufacturing, measurement and calibration, scientific research and technical services, committed to providing customers with technical services and comprehensive solutions of detection and testing, certification and evaluation, appraisal, consultation, training, and instruments and equipment in fields of quality, environmental protection, green, safety, health, and energy conservation.

Fiber Materials for Strengthening:
Carbon fiber fabric, carbon fiber laminate (plate), basalt fabric, basalt laminate (plate), glass fiber fabric, aramid fiber fabric, etc.
Adhesives for Strengthening:
Carbon fiber impregnating adhesive, primer, putty filler, steel-bonding adhesive, anchoring adhesive (rebar adhesive/grout), crack repair adhesive, cementitious grout, etc.
The laboratory can perform dynamic low-cycle fatigue tests and program-controlled fatigue tests on anchor products, as well as static tests under constant rate, constant strain, and constant stress control, along with various conventional mechanical property tests, to evaluate their fatigue life and safety of actual specimens.
Anchoring Systems:
Various types of metal anchors, chemical (adhesive) anchors, cast-in-place embedments (cast-in anchors), cast-in channels (Halfen channels), etc.
Pull-out Tests (In-Situ):
Anchoring components (metal anchors, chemical anchors, etc.), carbon fiber product strengthening systems.
Seismic Performance Testing:
Chemical anchors, mechanical anchors, cast-in channels, various anchor embedments, etc.
Fatigue Performance Testing:
Chemical anchors, mechanical anchors, cast-in channels, various anchor embedments, etc.
Fire Resistance Testing:
Chemical anchors, mechanical anchors, cast-in channels, various anchor embedments, etc.
Durability Testing:
Long-term load performance, freeze-thaw cycling, high temperature resistance testing, corrosion resistance testing, etc.
Miscellaneous Analysis:
Anchor material composition analysis, thickness measurement of zinc plating (galvanized coatings), adhesive composition analysis, etc.
