Frequently Asked Questions
What makes hot-dip galvanized steel ground screws more corrosion-resistant?
Hot-dip galvanizing involves immersing steel screws in molten zinc at 440-465°C, forming a durable zinc-iron alloy layer. This provides 10-20 years of protection even in harsh coastal or snowy environments.
How are these ground screws installed?
Installation is fast and eco-friendly. Use a hydraulic driver to screw them directly into soil. This reduces labor costs by 30-50% compared to concrete foundations and requires no excavation.
What is the typical load-bearing capacity?
Standard models (76-114mm diameter) offer horizontal torsion resistance up to 60kN and vertical bearing capacity up to 175kN. Capacity can be further enhanced with reinforced helical blade designs.
Are they suitable for extreme cold climates?
Yes. Made from Q235B steel with HDG coating, they are tested to withstand -40°C without brittleness. They are ideal for permafrost or regions with heavy snowfall.
What quality standards do these screws meet?
Products comply with international standards including ISO 9001, ISO 1461, and ASTM A123. They undergo rigorous testing such as 2,000+ hour salt spray tests and mechanical load simulations.
Can the size be customized for specific projects?
Yes, we offer both standard and custom sizes for the screws and blades to ensure optimal stability based on your specific soil conditions and project requirements.
