FAQ
Q1: What makes hot-dip galvanized steel ground screws more corrosion-resistant than other types?
A: Hot-dip galvanizing involves immersing steel screws in molten zinc at 440-465°C, forming a durable zinc-iron alloy layer that resists rust and corrosion. This process provides 10-20 years of protection, even in harsh environments like coastal areas with high salt exposure or regions with heavy snowfall . Electro-galvanized (EG) coatings, by contrast, offer thinner zinc layers and are less suitable for extreme conditions .
Q2: How are these ground screws installed, and do they require specialized equipment?
A: Installation is fast and eco-friendly:
No excavation needed: Use a hydraulic driver or machine to screw them directly into soil, reducing labor costs by 30-50% compared to concrete foundations .
Adaptable to terrain: Suitable for frozen soil, deserts, and rocky areas. Pre-installation soil testing (e.g., pull tests) ensures optimal embedment depth and stability .
Q3: What load-bearing capacity do these screws have?
A: Load capacity depends on size and soil conditions:
Standard models: Diameter 76-114mm, length 1,200-4,000mm, with horizontal torsion resistance up to 60kN and vertical bearing capacity up to 175kN .
Reinforced designs: Double or quadruple helical blades enhance grip in loose or sandy soils .
Q4: Are they suitable for solar projects in extreme climates like Russia?
A: Yes. These screws excel in low-temperature environments:
Material: Made from Q235B steel with hot-dip galvanizing (HDG), tested to withstand -40°C without brittleness .
Freeze-thaw resistance: HDG coating prevents ice-induced structural damage, making them ideal for permafrost or snowy regions .
Q5: What certifications and quality guarantees are provided?
A: Reputable suppliers comply with:
International standards: ISO 9001, ISO 1461 (corrosion resistance), and ASTM A123 for galvanizing quality .
Testing: Salt spray tests (2,000+ hours) and mechanical load simulations ensure durability .
Warranty: Up to 20 years of service life under normal conditions .
