What Is a 1 4 Tie Wire Anchor and Why It Matters for Solar Projects
A 1 4 tie wire anchor is a critical component in photovoltaic foundation systems, designed to secure solar panel mounting structures directly into the ground without the need for concrete curing. These helical piles, often referred to as ground screws or screw piles, provide a rapid and environmentally friendly alternative to traditional concrete footings.
For procurement managers overseeing large-scale PV projects, understanding the role of these anchors is essential. They serve as the primary load-bearing interface between the solar array and the soil, ensuring stability against wind loads, seismic activity, and environmental shifts. At Hebei Shijing Changtian Metal Structure Products Co., Ltd., our 1 4 tie wire anchors are engineered to meet rigorous international standards, offering reliable performance in diverse geological conditions.
Our helical piles feature hot-dip galvanized coatings with zinc layer thicknesses of not less than 85μm, ensuring a salt spray test life of over 3000 hours. This durability significantly reduces long-term maintenance costs and mitigates the risk of project delays caused by foundation failures.
Quality Control and Manufacturing Excellence for Durable Anchors
Hebei Shijing Changtian operates two major production plants covering 25,000 square meters, equipped with automated production lines that increase efficiency by over 40%. Our commitment to quality ensures that every 1 4 tie wire anchor undergoes strict inspection from raw material intake to finished product delivery.
ISO Certified Production Standards
We hold ISO9001, ISO14001, and ISO45001 certifications, reflecting our dedication to quality management, environmental responsibility, and occupational health and safety. These certifications guarantee that our manufacturing processes meet global benchmarks, providing buyers with confidence in supply chain reliability.
Advanced Material Strength
Our anchors utilize high-strength materials such as Q235B and Q355B, which far exceed industry averages for base material strength. This robust construction ensures that our helical piles can withstand extreme wind loads and complex geological pressures, reducing the risk of structural failure.
Scalable Production Capacity
With an annual output of 3 million pieces and a daily supply capacity of 30,000 units, we support large-volume orders for utility-scale PV projects. Our intelligent production scheduling minimizes lead times, enabling "lightning delivery" that keeps your project on schedule.
How to Choose the Right 1 4 Tie Wire Anchor for Your Project
Selecting the appropriate anchor system requires careful consideration of geological conditions, load requirements, and environmental factors. A well-informed selection process prevents costly retrofitting and ensures optimal project performance.
Geological Adaptability
Different soil types require specific anchor designs. Our helical piles are available in outer diameters ranging from 60mm to 140mm, adapting to sandy soil, clay, and soft soil layers. For soft soils, extended spiral designs provide enhanced grip, while hard soils benefit from optimized pile lengths.
Corrosion Resistance
In coastal or saline-alkali environments, corrosion resistance is paramount. We strictly follow the GB/T 13912 standard for hot-dip galvanizing, ensuring a zinc layer thickness of at least 85μm. This provides a salt spray test life of over 3000 hours, protecting your investment in harsh conditions.
Load-Bearing Capacity
The anchor must support both dead loads and dynamic wind loads. Our R&D team uses mechanical simulation and third-party testing to validate load capacities. Customized specifications ensure that each anchor meets the precise engineering requirements of your PV project.

Common Procurement Problems with Ground Screws and Solutions
Procurement buyers often encounter challenges related to corrosion, installation efficiency, and supplier capability. Here are common issues and how SJCT addresses them.
Problem: Premature Corrosion
Solution: We use hot-dip galvanization compliant with GB/T 13912, ensuring zinc layers >85μm. This provides superior protection against rust compared to electro-galvanized alternatives, extending service life in humid or saline environments.
Problem: Installation Delays
Solution: Our helical piles can be installed in approximately 3 minutes per unit using hydraulic torque drivers, which is 50% faster than traditional concrete foundations. This efficiency significantly reduces labor costs and accelerates project timelines.
Problem: Inconsistent Supply
Solution: With two production bases and 25,000 sqm of factory space, we maintain a 10,000-ton inventory level. This allows us to fulfill large-volume orders quickly and avoid supply interruptions during peak demand periods.
