In the booming PV and construction industries, the quality of foundation components is the key to ensuring project stability and long-term operation. Hot-dip galvanized ground piles, featuring precision spiral design and long-term anti-corrosion performance, have emerged as a core supporting product, injecting strong impetus into the high-quality development of PV power generation and construction engineering.
Long-term anti-corrosion performance is the fundamental advantage of hot-dip galvanized ground piles, addressing the core pain point of foundation corrosion in complex environments. Adopting advanced full-body hot-dip galvanizing technology, the pile surface forms a uniform and dense zinc-iron alloy coating with a thickness strictly controlled above 86μm—far exceeding the industry average of 65μm. This coating acts as a "protective shield" that effectively resists erosion from moisture, saline-alkali, industrial waste and other corrosive factors. Practical verification shows that in coastal saline-alkali zones, high-humidity mountainous areas and industrial parks, these ground piles can maintain intact anti-corrosion performance for over 30 years, which is twice the service life of traditional painted ground piles. In a 120MW PV project in Southeast China's coastal areas, after 6 years of exposure to sea breeze and heavy rainfall, the hot-dip galvanized ground piles still have no rust spots or peeling, ensuring stable support for the PV module array.
pitch controlled at 150-200mm and blade thickness up to 12mm. This structure enables the ground pile to form a "mechanical interlock" with the soil during installation, increasing the vertical bearing capacity by 30% compared with straight piles and the lateral anti-overturning capacity by 40%. In the 50MW PV project in Northern Gobi, where wind force often reaches level 8, Yuhao ground piles support the PV modules stably without any displacement.The precision spiral design further elevates the product's load-bearing capacity and adaptability, making it suitable for both PV and construction scenarios. The R&D team customizes spiral parameters based on geological surveys: the blade pitch is precisely adjusted between 140-210mm, and the blade thickness is optimized to 12-15mm, forming a scientific "soil interlocking structure" with the ground. This design increases vertical bearing capacity by 35% compared with straight piles and enhances lateral anti-overturning performance by 45%, easily coping with extreme weather such as strong winds and heavy snow. In Northern China's Gobi PV base, where wind speeds often reach level 9, the precision spiral ground piles firmly anchor the PV brackets without any displacement. In construction fields like lightweight steel villas and temporary construction sites, they can be quickly screwed into the ground without concrete pouring, reducing construction time by 50% and lowering overall project costs by 12%.
The combination of the two core technologies brings efficient construction experience. The spiral structure allows quick screwing into the ground without concrete pouring, reducing construction time by 50%. Up to now, Yuhao PV ground piles have been applied in more than 200 large-scale PV projects nationwide, with a total installed capacity exceeding 5GW. Customers in Inner Mongolia, Xinjiang and other regions highly praise its reliability in harsh environments.
Yuhao PV ground piles, with hot-dip galvanizing and spiral support as dual guarantees, not only meet the strict requirements of PV projects but also create greater value for customers. Choose Yuhao to lay a solid foundation for green energy projects!
