Outperform traditional foundations with ground screw anchors—the modern solution for rapid, eco-friendly structural stability. Unlike concrete footings that require excavation, curing time, and environmental disruption, ground screw anchors install in minutes using specialized equipment. They transfer structural loads directly into stable subsoil layers, providing immediate load-bearing capacity without waiting days for concrete to set. Ideal for decks, solar farms, fencing, and light buildings, this system eliminates weather delays and soil erosion risks.

Why Choose Ground Screws Over Concrete?

Speed & Efficiency: Install anchors in hours, not days, with minimal site disturbance. No curing means projects proceed instantly.

All-Season Reliability: Frost heave? Flooding? Ground screw anchors maintain integrity where concrete cracks or shifts. Their helical design grips below frost lines, preventing seasonal movement.Zero Environmental Damage: Avoid concrete’s carbon footprint and soil contamination. Screws leave no residue and are 100% removable/reusable.

Cost Savings: Reduce labor, equipment rentals, and material waste. No mixing, pouring, or formwork required.

Technical Superiority
Engineered from hot-dip galvanized steel, these anchors withstand corrosion while supporting loads up to 50kN (varies by soil class). The helical plates compact, rather than displace soil during installation, enhancing pull-out resistance. Tests show 200% greater tensile strength versus concrete in sandy or clay-heavy soils.

The Science Behind Soil Anchoring
Concrete relies on sheer mass, while ground screw anchors use engineered friction and bearing capacity. This creates a dynamic “lock” with the earth, adapting to soil density changes that fracture static concrete. Independent studies confirm a 30% longer lifespan in high-moisture zones.

Ground screw anchors have become a go-to foundation solution across industries thanks to their speed, stability, and eco-friendliness. Hebei Minmetals’ ground screws have been widely applied in both commercial and residential projects. Below are several real-world examples where our metal ground screws delivered outstanding performance.

1. Ground Screws for Fence Posts

In a suburban residential project in Canada, homeowners opted for ground screws for fence posts instead of traditional concrete foundations. With uneven terrain and tight timelines, the installation team used Hebei Minmetals ground screws to secure fence panels. The process was completed within a single day, offering a durable, frost-resistant base without digging or curing time.

2. Ground Screw Anchor for Decks

A vacation cabin in Norway utilized ground screw anchors for decks, avoiding the need for excavation in rocky soil. The project required minimal machinery, reduced labor, and eliminated the environmental impact of concrete. The elevated wooden deck has stood strong for over five years, proving the long-term stability of screw foundations in challenging terrain.

3. Ground Anchors for Buildings and Outdoor Spaces

Ground screws are increasingly replacing concrete footings for light commercial buildings. One notable case was a shed base installation in the UK. By using metal ground spikes and screws, the customer achieved a secure base within hours. Similarly, a carport installation in Australia leveraged our screws to anchor steel columns, avoiding underground utilities and reducing installation costs by 40%.

4. Solar, Signage, and Towers

For a solar farm in Southeast Asia, Hebei Minmetals supplied over 2,000 ground anchors to support solar racking systems. The screws were installed without disturbing the soil’s natural profile, ensuring long-term integrity. Additionally, our screws have been used for signage posts, temporary lighting, and communication towers, where quick deployment is essential.

5. Household and Recreational Applications

In household and lifestyle projects, ground screws are gaining popularity. DIYers have used them to install garden arches, playhouses, and pergolas. Even shooting sport structures and greenhouses are now securely mounted using our products, proving that ground screws are as versatile as they are reliable.

① Prep the Site

Clear rocks/roots where screws will go.

Pro tip: Spray-paint screw locations to avoid misalignment.

② Start the Screw

Attach the drive head to your motor.

Position the screw perfectly vertical (even 5° off risks wobble).

Don’t force it: If the screw stops spinning, reverse ¼ turn – forcing it bends shafts.

③ Drive to Depth

Run the motor at 25-35 RPM (high torque, low speed).

Stop when:

Torque spikes suddenly (you’ve hit bedrock/compact layer).

Depth reaches below the frost line (check local codes – typically 4+ ft).

④ Attach Your Structure

Bolt mounting brackets directly to the screw head.

Shim for precision leveling – never bend the screw to adjust height.

3 Critical Mistakes to Avoid
Skipping Soil Checks

Sandy soil? Use wider helix plates.

Clay? Slow rotation to prevent "corking" (soil compaction around threads).

Ignoring "Refusal" Signs

If the screw won’t budge after reversing, relocate – don’t sacrifice integrity.

Over-Torquing

Excessive force strips threads. Use a gauge – most screws max at 2,500-3,500 Nm.

Testimonials of Ground Screw Anchor

Robert

Solar Installation Contractor (USA)

"We’ve been using Hebei Minmetals ground screw anchors for all our off-grid solar panel installations, and the results have been excellent. No need for concrete—just drive them in, level the base, and start mounting. These metal ground screws save us time and labor on every job."

Amelia

Event Organizer (UK)

"For temporary structures like tents and fencing at outdoor festivals, the earth anchors from Hebei Minmetals are a game changer. They’re easy to install, hold up well in soft and hard soil, and are reusable for future events. Strongly recommend them for any temporary setups."

Jorge

Farm Manager (Spain)

"We use ground screw anchors for securing vineyard trellises and animal enclosures. The stability is remarkable, even during storms. Hebei Minmetals provides consistent quality and prompt delivery, which is essential for our seasonal schedules."

Mia

DIY Enthusiast (Canada)

"I was surprised at how easy it was to install my backyard deck using metal ground screws instead of digging and pouring concrete. The ground screw anchors from Hebei Minmetals were strong, aligned perfectly, and held up all winter without shifting. I’ll definitely use them again!"
