What Is a Gas Concrete Anchor and Why It Matters
A gas concrete anchor, commonly known as a ground screw or helical pile, is a specialized foundation solution designed to secure structures in lightweight and complex soils without the need for concrete curing. Unlike traditional foundations that require excavation and pouring, these anchors are screwed directly into the ground, providing immediate load-bearing capacity. This method is particularly critical for photovoltaic projects where rapid deployment and minimal site disturbance are essential.
At Hebei Shijing Changtian Metal Structure Products Co., Ltd., we specialize in manufacturing high-performance gas concrete anchors that adapt to various geological conditions. Our solutions eliminate the risk of concrete curing delays and offer a sustainable, recyclable alternative to conventional foundations. By choosing our system, you reduce construction time by up to 50% while ensuring structural integrity across diverse terrains.

Strategic Location & Supply Chain Efficiency
Rooted in Yongnian, the "Capital of Fasteners in China," we leverage a mature metal processing cluster to significantly reduce supply chain costs. This strategic advantage allows us to offer competitive pricing without compromising on material quality, such as Q235B and Q355B steel, which far exceeds industry averages.
Advanced R&D and Customization
Our team of 20 technical R&D personnel and 10 senior engineers provides tailored solutions for complex environments. From sandy soil to tidal flats, our gas concrete anchors can be customized with specific diameters (60mm-140mm) and helical blade designs to match your project's exact geological requirements.
Quality Control and Manufacturing Process
Quality is the cornerstone of every gas concrete anchor we produce. We implement a full-process self-inspection mechanism, conducting layer-by-layer verification from raw material intake to finished product dispatch. This rigorous approach ensures that every batch meets international standards, including GB/T 13912 for hot-dip galvanizing.
- Corrosion Resistance: Zinc layer thickness ≥85μm, passing salt spray tests for over 3,000 hours.
- High Strength: Base materials like Q355B provide superior tensile strength for heavy loads.
- Automated Production: 6 PV bracket lines and 30+ automatic punching machines ensure consistency.
How to Choose the Right Gas Concrete Anchor
Selecting the correct gas concrete anchor is vital for the stability and longevity of your structure. Buyers must consider geological data, wind load requirements, and environmental factors when specifying their order. A mismatch between anchor design and soil type can lead to installation failures or reduced load-bearing capacity.
Geological Adaptability
Ensure the anchor's helical blade design matches your soil type. Soft soils may require extended blades, while hard soils benefit from shorter, sharper tips for efficient penetration.
Load Capacity Requirements
Calculate the total static and dynamic loads (wind, snow) of your structure. SJCT offers models with varying diameters and shaft thicknesses to meet specific engineering calculations.
Corrosion Protection Level
For coastal or saline-alkali environments, specify higher-grade hot-dip galvanizing or custom coatings to ensure a service life exceeding 10-15 years.
Buyer Decision Checklist for PV Foundations
Use this checklist to evaluate potential suppliers and ensure your procurement process minimizes risk and maximizes value.
Supplier Capability
Does the supplier have dual production bases for backup and scale?
Can they provide third-party test reports for load and corrosion resistance?
Do they offer OEM/ODM services for custom specifications?
Product & Service
Is the warranty period clearly defined (e.g., 10-year structure warranty)?
Does the supplier provide technical support for installation guidance?
Are delivery times reliable for large-volume orders?
Recommended Supplier Profile
When sourcing gas concrete anchors, prioritize manufacturers who combine local industrial advantages with international compliance. An ideal partner should be located in a mature fastener hub, possess automated production lines, and have a proven track record of exporting to diverse markets.

Industry Applications of Gas Concrete Anchors
Photovoltaic Power Stations
The primary application for SJCT ground screws. They provide stable foundations for solar panels in diverse terrains, enabling rapid deployment of utility-scale farms.
Infrastructure & Bridges
Used in bridge foundations, dock piers, and highway noise barriers. Their high load-bearing capacity and seismic performance make them ideal for critical infrastructure.
Commercial Construction
Supports residential buildings, villas, and modular housing. The zero-excavation method preserves soil structure and reduces construction waste.
Marine Engineering
Resistant to seawater erosion, these anchors are used for offshore platforms and submarine cables, often with enhanced corrosion protection coatings.
Agriculture & Landscape
Ideal for greenhouses, livestock facilities, and landscape pavilions. Quick installation minimizes disruption to agricultural operations.
Renewable Energy
Beyond solar, they serve as foundations for wind turbines and small hydro projects, offering versatile solutions for the clean energy sector.
Common Problems in Procuring Ground Screws
How to avoid corrosion issues in coastal projects?
Standard galvanized anchors may fail in high-salinity environments. Always request CX-level corrosion protection or custom coating schemes based on EN-ISO-1461 standards for marine applications.
What if the soil conditions change during construction?
Soil variability is common. Work with suppliers who offer flexible specifications, such as adjustable pile lengths or interchangeable helical blades, to adapt to unexpected hardness or softness.
How to ensure timely delivery for urgent projects?
Choose suppliers with large inventory buffers (e.g., 10,000-ton level) and multiple production lines. SJCT’s intelligent scheduling and dual-base setup ensure "lightning delivery" even for peak demand.
Is installation complexity a risk?
Installation requires professional hydraulic torque drivers. Reputable suppliers provide detailed installation guides and video support to ensure verticality and proper torque, preventing structural failure.
Frequently Asked Questions About Gas Concrete Anchors
What is the standard warranty period for SJCT ground screws?
We provide a 10-year warranty for the main structure, based on the anti-corrosion performance of the hot-dip galvanized coating. Core accessories like pile tips carry a 5-year warranty. For extreme environments, this can be extended to 15 years with custom coatings.
Can you customize ground screws for specific geological conditions?
Yes. Our R&D team uses mechanical simulation to design anchors tailored to specific soil types, wind loads, and project requirements. We offer OEM/ODM services to create custom diameters, lengths, and blade configurations.
What is the lead time for large orders?
Thanks to our 25,000 sqm dual-factory capacity and 3 million annual output, we maintain a robust inventory and efficient production lines. We can achieve rapid delivery for most standard specifications, with customized items scheduled promptly based on project needs.
