From factory to project, strict control throughout - Hot-dip galvanized spiral ground piles, choose for peace of mind

For foundation products like hot-dip galvanized spiral ground piles, quality control from factory production to project application directly determines customers' peace of mind. Our ground piles implement strict whole-process management, integrating premium raw materials, precise manufacturing and professional on-site supervision, becoming the reassuring choice for PV and engineering projects.
Factory control starts with raw materials—we only select Q355 high-strength steel, with each batch inspected for tensile strength and ductility. The fully automated production line realizes precision processing of spiral blades: variable-pitch parameters (140-210mm) are set by computer numerical control, and blade thickness (16mm) is monitored in real time. The hot-dip galvanizing process is the key: 450℃ constant-temperature zinc liquid, 90μm-thick zinc-iron alloy layer, and 360° full-body coating, all inspected by ultrasonic thickness gauges to ensure compliance with national standards.
Before delivery, each pile undergoes salt spray corrosion testing and load-bearing performance testing, with unqualified products directly eliminated. On project sites, professional technicians conduct geological re-inspection, customize installation parameters, and supervise the spiral screwing process to ensure the "mechanical interlock" with soil is firm. Post-installation, bearing capacity detection and anti-corrosion layer inspection are mandatory.
Practical results prove this strict control: in Shandong's coastal saline-alkali PV project and Qinghai's high-altitude cold project, our piles have operated stably for years without rust or displacement. Service life exceeds 30 years, with no frequent maintenance like traditional piles. From factory to project, every link is strictly controlled—choose our hot-dip galvanized spiral ground piles, and gain true peace of mind for your project.
