On January 12, 2026, our company successfully completed the CNAS (China National Accreditation Service for Conformity Assessment) on-site review.

With a rigorous quality management system and solid technical strength, we have been accredited for a number of core testing parameters, elevating our professional service capabilities to a new level.

During the review, in accordance with international accreditation criteria, the CNAS expert panel conducted a comprehensive and rigorous inspection of our laboratory management, technical capabilities, personnel operations, equipment configuration and other aspects.

At the review meeting, our technical and management teams had in-depth exchanges with experts, carefully cooperated with all inquiries and verifications, fully demonstrating a professional, pragmatic work style and standardized, efficient operation.

The core parameters accredited in this review include:

• Routine testing parameters for building materials such as steel bars and concrete

• Building energy dissipation and damping devices (displacement-dependent dampers, velocity-dependent dampers)

• Full-scope testing parameters for seismic isolation products:

building seismic isolation rubber bearings, friction pendulum seismic isolation bearings, elastic sliding seismic isolation bearings, etc.

The acquisition of CNAS accreditation marks that our technical and management capabilities in the testing of building materials and seismic isolation & energy dissipation devices have reached internationally recognized standards.

Our test reports are eligible for mutual recognition in many countries and regions worldwide, laying a solid foundation for providing customers with more authoritative and credible testing services.

In the future, taking CNAS accreditation as a new starting point, our company will continue to deepen the field of construction engineering quality testing, continuously enhance technological innovation and service levels, and contribute greater efforts to ensuring engineering quality and safety and promoting high-quality development of the industry.
