CTI has the professional inspection and certification team, which can provide customers with quality assurance and expediting services in accordance with American standards, Japanese standards, European international standards and GB standards.

CTI provides steel structure inspection services related to building materials and construction engineering. The rapid development of the steel industry has become an important economic lifeline of our country. Under this background, steel structure engineering technology has developed rapidly, and non-destructive testing is an indispensable technology for industrial development. Tools and technological level can already be used to measure the industrial level of a country to a certain extent. CTI is committed to providing one-stop professional facility safety and quality assurance for public buildings, industry, commerce, infrastructure and other fields at home and abroad.

CTI has the professional certification team that can audit the factory in accordance
with ISO 3834/EN1090 requirements, and review relevant qualifications, and finally issue
certificates.

CTI provides stainless steel heavy metal detection services related to measurement audits. Measurement audits: An activity where a participant performs actual tests on the tested items and compares the test results with reference values. Note: Measurement audit is a proficiency testing plan that conducts a "one-to-one" ability evaluation of a participant

High-carbon industries such as power generation, petrochemicals, building materials, and steel, as well as emission-intensive enterprises, and related investment consulting firms and management organizations, benefit from carbon management system certification services provided by CTI Certification.

Tableware and kitchenware include various pots and pans and various kitchen tools, etc. In addition to the sanitary, physicochemical and microbiological requirements for food contact materials, the tableware and kitchenware standard also include physical requirements, such as the insulation performance and sealing performance of heat preservation containers, and the corrosion resistance of stainless steel tableware. As an independent third-party inspection, identification, testing and certification organization, CTI provides a comprehensive one-stop solution for food-grade hygiene requirements, microbiological and physical performance testing of tableware and kitchenware, helps enterprise's products comply with corresponding regulatory and requirements, improves product quality and reduces the risk of non-compliance.

CTI NDT is Specialized in non-destructive testing services and personnel training for special equipment, rail transit, building steel structure, petrochemical industry, electric power facilities, marine engineering, bridge network, hardware profiles and other industries. CTI is the most influential and strength of non-destructive testing institutions in China. CTI nondestructive testing can help enterprises understand and evaluate the structure and quality of tested materials and equipment components more comprehensively, directly and deeply, and help to monitor product quality and improve process.

Generally sandwich structure is used for wings, tail, fuselage, speed brake, engine compartment, etc. Compared with thin-walled skins, sandwich panels have a much larger thickness, strong resistance to instability, smooth surface, and good aerodynamic appearance. However, due to the complex manufacturing process and the difficult inspection of process quality, the application is greatly restricted. The materials of the sandwich structure sheet mainly include aluminum alloy, stainless steel, titanium alloy and various composite materials. Interlayer materials include light wood, foam plastic, etc., and metal or composite materials can also be used to make corrugated interlayer or honeycomb interlayer. The interlayer and the surface board are generally glued together, or they can be welded to form a whole.

Rebound method to detect concrete strength, core drilling method to detect concrete strength, post-anchorage inspection and drawing, concrete mass temperature measurement, concrete internal defects, steel protection layer thickness, steel spacing, number of steel bars, floor thickness, steel corrosion detection.

CTI provides component scanning services related to Party A's full-process quality control. The component scanning includes the inspection and inspection of the thickness of the steel bar protection layer and the steel bar spacing. The detection range is mainly the components and parts where the position of the steel bar may significantly affect the bearing capacity and durability of structural components, such as the longitudinally stressed steel bars of beams and slab components. Component scanning reflects the physical performance of the structure from the perspective of the steel reinforcement in the concrete structure.

CTI provides physical testing services for concrete structures related to building materials and construction projects, including rebound method to detect concrete strength, core drilling method to detect concrete strength, post-anchorage inspection and drawing, concrete mass temperature measurement, concrete internal defects, steel protection layer thickness, steel bars Spacing, number of steel bars, floor thickness, steel corrosion detection.

CTI provides Party A’s full-process quality control related steel engineering quality assessment services, and pays attention to common quality defects through inspections of steel engineering construction nodes.
