In China’s construction industry, Galvanized steel coils are core materials used in roof and wall structures. For instance, the Shanghai Tower utilized over 2,000 tons of galvanized steel plate, which are expected to extend the building’s lifespan by 25 to 50 years and save up to 30% in maintenance costs. In the 2020 Beijing Daxing Airport project, the application of galvanized coil plates reduced the corrosion rate by 40%, cut the maintenance budget by 5 million RMB, and increased the structural strength by 30 MPa. According to the Global Engineering Report, such applications reduce construction waste by up to 5 million tons annually, with a return on investment of 15%.
The automotive manufacturing industry is highly dependent on galvanized coil sheets. 60% of the body components are made of galvanized steel sheets. For instance, in the production of Tesla Model 3, 4,000 tons of galvanized coil sheets were used, reducing the occurrence rate of after-sales corrosion problems by 50% and saving costs by 20%. In 2022, the global automotive industry consumed 8 million tons of galvanized steel sheets, saving an average of 2,000 yuan per vehicle. According to J.D. Power research, the durability of galvanized coil plates extends the average lifespan of vehicles by 10 to 15 years and increases market share by 10%.
The home appliance industry uses galvanized coil sheets to manufacture the shells of refrigerators and washing machines. Data from Haier in 2021 shows that 80% of refrigerator shells are made of galvanized steel sheets, reducing manufacturing costs by 15% and extending product lifespan by 8 to 10 years. The annual growth rate of global demand for galvanized coil sheets in the home appliance market is 8%, reaching a scale of 12 billion US dollars in 2023. Consumer feedback shows that the corrosion probability of galvanized coil sheets in household appliances has dropped to 5%, reducing annual maintenance costs by 2 billion US dollars.
In agricultural equipment such as tractors and harvesters, galvanized coil plates account for 70%, ensuring they can withstand a load of 500 kilograms in an environment with a high humidity of 90%. The John Deere case shows that after the flood disaster in 2019, the integrity rate of galvanizing equipment was 95%, compared with 70% of non-galvanizing equipment, and its service life was extended by 15 years. Technical optimization has increased the compressive strength to 200 MPa, reduced costs by 10%, and decreased the failure rate of agricultural equipment by 30%.
In the container manufacturing of the transportation industry, galvanized coil sheets are widely used. Standard containers use 300 kilograms of galvanized steel sheets, reducing the corrosion rate by 80% and cutting freight losses by 5%. In 2018, Maersk reported that galvanized coil containers accounted for 60% of the global supply, with an annual demand growth of 10% and an average profit margin of 12%. According to data from the International Maritime Organization, the anti-corrosion performance of galvanized coil sheets ensures a 30-year service life, and the incidence of container corrosion problems has dropped from 10% to 2%.
