Galvanized Steel Plate gets coated in layers of zinc because rust won't attack this protective metal. The most external layer is all zinc, but successive layers are a mixture of zinc and iron, with an interior of pure steel. These multiple layers are responsible for the amazing property of the metal to withstand corrosion-inducing circumstances. Zinc also protects the steel by acting as a "sacrificial layer." If rust does take hold on the surface of Galvanized Steel Coil, the zinc will get corroded first. This allows the zinc that is spread over the breach or scratch to prevent rust from reaching the steel. For countless outdoor, marine, or industrial applications, Galvanized steel plate is an essential fabrication component.

The requirements of chemical composition of galvanized plate are different in different countries. The national standard is to detect the content of carbon, manganese, phosphorus, sulfur and silicon.
China Instrument Network Instrument R&D On January 31, 2018, Shanghai Metrology Institute took the lead, and cooperated with China Institute of Metrology, Beijing Institute of Metrology and Detection, Chongqing Institute of Metrology and Quality Inspection, China Metrology Association, and China Metrology and Testing. The project of the AQSIQ Scientific and Technological Planning Project “The Impact of the WTO/TBT Working Principles on the Typical Measuring Instruments Market in the Measurement Industry and Countermeasures†(Symbol No. 2015QK043) was successfully accepted by experts. Liu Xinmin, the former inspector of the AQSIQ, served as the leader of the project acceptance team. The team members consisted of leaders of some provinces and universities, technical experts of inspection agencies, chief engineers of exporters of measurement instruments, and financial experts. Shanghai Institute of Metrology, Deputy Dean Han Yu represented the project team to report on the project.
China is a major producer and exporter of measuring instruments. In recent years, with the development of foreign trade in measuring instruments in China, trade frictions have been aggravated and technical trade barriers have gradually emerged. In order to improve the manufacturing level and quality level of China's measuring instruments, protect the market of China's measuring instruments, and improve the international competitiveness of China's measurement instrument industry, it is necessary to conduct research on the WTO/TBT working principles to enhance China's ability to respond to technical trade barriers and promote China's measurement instruments. Industrial development. Within two and a half years, the project team analyzed the causes, main manifestations of technical barriers to trade and their impact on the import and export of measuring instruments and the mechanism of action. Taking six types of typical measuring instruments such as electric energy meter, gas meter, water meter, pressure gauge, heat meter and weighing instrument as examples, the impact of the WTO/TBT working principle on the measurement industry was studied, and countermeasures for the measurement industry to deal with technical trade barriers were proposed. At the same time, he wrote "China's Gas Meter Industry and Market Analysis Report", "China's Heating Measurement Industry and Market Analysis Report" and "China's Electric Vehicle Recharge Measurement Industry Market Research Report", providing technology for measuring instrument manufacturing industry to deal with technical trade barriers. References provide the basis for government departments to formulate relevant policies.
The project fills the gap in the domestic measurement instrument manufacturing industry's response to the impact of technical barriers to trade, will effectively promote the quality of China's measuring instrument products, help China's export of measuring instruments and products along the “Belt and Road†countries, and accelerate China’s manufacturing of large measuring instruments. Towards a manufacturing powerhouse for measuring instruments.
