Xiamen Angels Solar Energy Co., Ltd. is a professional manufacturer with over 15 years of experience providing cost-effective, high-efficiency full solar mounting solutions. Our customized hot dip galvanized helical ground screw pile system serves as the foundational anchoring component for all ground PV mounting brackets, perfectly replacing traditional concrete footings to deliver stable, low-cost foundation support for solar panel arrays.
This PV helical pile is fabricated from high-strength Q235B carbon steel with integrated spiral helical blades, finished by full hot-dip galvanization with uniform zinc coating over 85μm. The dense zinc-iron alloy layer delivers outstanding anti-rust, salt spray, acid & alkali corrosion resistance, adapting to coastal saline land, desert soil, frozen ground, mountain slopes and all kinds of complex terrain.
Optimized spiral blade structural design allows direct rotary installation into soil without excavation, concrete pouring or long curing cycles. Symmetrical helical blades lock tightly with surrounding soil to deliver powerful vertical bearing capacity, anti-pull and anti-lateral displacement performance, firmly resisting strong wind loads and heavy snow pressure. Supported full OEM & ODM customization: pile length, pipe diameter, wall thickness, helix quantity, flange size and top connecting structure can be tailored to match all our ground solar racking systems and local geological conditions.
As an ISO 9001 certified factory with daily output of 5,000 ground screws, we implement full-process raw material inspection, welding test and salt spray aging test for every batch. The helical ground pile matches the 25+ year service life of solar panels, with a 15-year product warranty and zero maintenance during outdoor operation.
Wide Application Scenarios
1.Utility-Scale Ground Solar Farms
Large centralized photovoltaic bases, desert PV power stations, mountain slope solar projects. Mass installation cuts construction cycle and overall civil engineering investment significantly.
2. Agrivoltaic & Fishery-Solar Complementary Projects
Agricultural solar greenhouses, fish pond distributed PV systems, farmland solar racking. No large-area excavation protects farmland surface soil and crops.
3. Residential & Commercial Distributed PV Systems
Household backyard solar ground mounts, factory ground solar brackets, villa small photovoltaic power stations, lightweight and easy to construct for small & medium projects.
4. Other Outdoor Foundation Supporting Works
Solar carport mounting foundations, solar street light poles, garden fences, wooden deck bases, billboard fixing piles and small wind energy equipment foundations.

Customer Design
Our engineers design efficient ground screw anchors to have certain attachments or have specialized ends to penetrate hard surfaces for your outdoor space.
Ground Screw is widely used in medium to large-scale solar farm installation. Material of ground screw is Q235B steel. The hot-dip galvanized treatment over ground screw surface ensures the ground screw to be anti-corrosive.
1. 15-Year Professional Solar Mounting Factory
Xiamen Angels Solar supplies cost-effective solar racking solutions, customized hot dip galvanized helical ground piles for all PV ground systems.
2. Heavy-Duty HDG Anti-Corrosion Structure
Q235B steel with ≥85μm hot-dip zinc coating, excellent salt & acid resistance, service life over 25 years with 15-year factory warranty.
3. Fast Installation Without Concrete Foundation
Screw directly into soil by rotary machine, no excavation or curing; high anti-pull & bearing capacity to resist wind and snow loads.
4. Wide Application for All PV Projects
Fit utility solar farms, agrivoltaic systems, residential & commercial distributed PV, solar carports and outdoor ground foundations; full OEM customization supported.
5. Eco-Friendly & Cost-Saving Recyclable Design
Protect original land vegetation, removable & recyclable after project retirement, greatly cutting construction time and total foundation investment.

Manufacturing Process
Step 1: Cutting
The length of welded pipe is 6 meters andthe welded pipe need to be cut by sawingmachine according to customer's need.
Step 2: Heating
Putting ground screw to high frequencyheating machine and make ground screwbe soft so that ground scew can beshaping.
Step 3: Shrinking
Using shrinkage machine to change theshape and diameter of ground screw.
Step 4: Punching
Using punching machine to do a hole orother for ground screw.
Step 5: Welding
The spiral blade of ground screw will bewelded by automatic welding machine.
Step 6: Galvanizing
The surface treatment is acid picking andhot dip galvanizing.
