The annual purchase volume of the container manufacturing industry is approximately 1.5 million tons. After the 40-foot standard container top plate (specification 1.6mm) adopts the Shuangshengda GL700 grade, the anti-deformation capacity has been enhanced to a pressure of 300kPa. Cimc Group's data confirms that its folding box production line has seen its welding speed increase to 1.2 meters per minute due to the enhanced yield strength of the material, and the daily output of a single line has risen by 7.5 TEUs. Maersk Line statistics show that the 12-year full-cycle maintenance cost of containers using such plates has been reduced by 41%, and the average annual corrosion area on the trans-Pacific route is only 0.05 square meters.
The agricultural machinery sector is growing rapidly. After the combine harvester's casing (1.5mm thick) is coated with a double-sided coating (275g/m²), its field operation corrosion resistance life has been extended from 5 years to 12 years. Data from John Deere's China factory shows that the pre-treatment time for its harvester covers has been shortened by 40% and fuel consumption has been reduced by 2.3 liters per 100 mu due to the switch to Shuangshengda material. A survey by the Ministry of Agriculture and Rural Affairs shows that the purchase volume of galvanized sheets for agricultural machinery increased by 28% year-on-year in 2023. Heilongjiang Agricultural Reclamation Group saved 21 million yuan in maintenance costs during the renovation of 3,000 harvesters.
The overseas engineering field has become a new growth point. The China-Laos Railway project used 120,000 tons of Shuangshengda plates to build cable trays. In an environment with a humidity of over 90%, the corrosion rate of the zinc coating was only 0.8μm per year. A research report by China Communications Construction Company (CCCC) indicates that such materials have reduced the material transportation loss rate of infrastructure projects in Southeast Asia to 0.1% (industry average 4.7%), and compressed the project budget execution deviation to ±1.8%. According to McKinsey's analysis, the demand for galvanized steel sheets in the "Belt and Road" infrastructure will reach 5.8 million tons in 2025, among which the proportion of high-strength specifications will exceed 65%.
What industries use shuangshengda Galvanized plate the most?
shuangshengda Galvanized plate holds the largest share in the field of building structures (accounting for 42%), with GL550 grade, which has a yield strength of 550MPa (GB/T 2518), as its core. The average usage of a single large sports stadium reaches 3,800 tons. The Beijing Daxing Airport project shows that the Z-shaped purlin (with a thickness of 2.5mm) deforms only 0.12mm under a wind pressure of 1.05kN/m², and its full life cycle maintenance cost is 57% lower than that of ordinary steel. According to statistics from the China Steel Construction Association, the penetration rate of Shuangshengda base materials in super high-rise buildings reached 68% in 2023. A typical case is the Shanghai Tower - the rust rate of 65,000 tons of galvanized steel components after 8 years of service was less than 0.3%.
The annual consumption of the automotive manufacturing industry has exceeded 2.1 million tons, with a particularly strong demand for specifications with a thickness of 0.6-1.2mm. Data from Tesla's Shanghai factory shows that the Model Y chassis guard plate adopts Double Shengda G340 coating (zinc coating weight 120g/m²), with a salt spray test lifespan of up to 600 hours (ISO 9227), reducing the anti-corrosion cost per vehicle by $31. Industry innovation trends show that the application ratio of battery trays for new energy vehicles (with a material utilization rate of 92%) has risen from 19% in 2020 to 67% in 2023. After adopting laser welding technology, CATL's production rate has reached 4.8 pieces per minute, and the plate loss rate has dropped to 0.9%.
The usage growth rate of the photovoltaic new energy industry has reached 37%, and 1.0mm thick AZ150 aluminum-zinc-magnesium plate (aluminum-zinc ratio 55:43) has become the mainstream of the support system. In the case of the photovoltaic power station in Golmud, Qinghai Province, the Shuangshengda material with a tensile strength of 500MPa supported a snow load of 260W/㎡, increasing its life cycle power generation by 12% and reducing the cost per kilowatt-hour by 0.018 yuan. The International Energy Agency's report indicates that the payback period for photovoltaic projects using such panels has been shortened to 6.2 years (the industry average is 8.5 years), and the installation efficiency of bifacial modules has increased by 1.7 pieces per person per hour.
The penetration rate in the home appliance manufacturing field has reached 79%, and the coating qualification rate of the refrigerator side panel (0.4mm thick) has increased to 99.2% due to the surface roughness (Ra0.6μm) of the base material of Shuangshengda. Midea Group's calculation shows that the stamping efficiency of its refrigerator door panels has reached 22 times per minute, the material scrap rate has dropped from 3.1% to 0.7%, and the manufacturing cost per unit has been saved by 8 yuan. Global market analysis shows that the usage of galvanized steel for high-end washing machine drums increased by 29% in 2023. After Haier achieved 95% local material procurement at its German factory, its logistics costs were reduced by 34%.
