Why Choose Us as Your Studs & Threaded Rods Supplier
Strategic Location & Supply Chain Efficiency
Located in Hebei's mature metal processing cluster, we minimize raw material procurement costs and lead times. This industrial synergy allows us to offer highly competitive pricing without compromising on material integrity, directly lowering your landed cost.
Massive Production Capacity
With 6 PV bracket production lines and over 30 automatic punching machines, we can produce up to 30,000 units daily. Our 10,000-ton inventory support ensures "lightning delivery," preventing supply chain interruptions for large-scale PV power station projects.
Adaptability to Harsh Environments
Our studs and threaded rods feature zinc layer thicknesses of ≥85μm and pass salt spray tests exceeding 3,000 hours. This superior corrosion resistance ensures long-term stability in high-humidity, saline-alkali, or coastal environments common in renewable energy sites.
Professional R&D and Customization
Backed by 20 technical R&D personnel and 10 senior engineers, we don't just sell standard parts. We engineer solutions for complex geologies like deserts and tidal flats, offering full OEM/ODM services to match your specific project load requirements.
Factory Capability & Manufacturing Scale
Dual-Base Production Power
Our operations span two major facilities: Hebei Shijing Changtian and Xingtai Changtian. The integration of these bases allows for parallel production modes that drastically reduce delivery times. Since 2021, our automated upgrades have increased production efficiency by over 40%.
Intelligent Scheduling
We utilize intelligent production scheduling to compress delivery times to the industry's shortest levels. This capability ensures that even urgent, large-volume orders for commercial construction or infrastructure reinforcement are fulfilled on schedule, protecting your project timelines.
Annual Output Value
3 Million Pieces Annually
Our robust output capacity supports both small-scale landscape installations and massive utility-scale solar farms, ensuring consistent supply regardless of project size.
Quality Control & Manufacturing Standards
Material Integrity
We use standard raw materials such as Q235B and Q355B, which offer base material strength far exceeding industry averages. Every batch undergoes layer-by-layer inspection from raw material intake to finished product dispatch, ensuring zero-defect delivery.
Corrosion Resistance Testing
Our hot-dip galvanizing process strictly follows GB/T 13912 standards. Products are tested for salt spray resistance lasting over 3,000 hours, guaranteeing durability in harsh environmental conditions typical of outdoor PV installations.
Certifications & Compliance
Our commitment to quality is validated by ISO 9001, ISO 14001, ISO 45001, and GB/T 27922 certifications, providing you with confidence in our systematic approach to manufacturing and safety.
Industry Applications & Use Cases
Renewable Energy Projects
Our threaded rods and ground screws serve as the core foundation for wind turbines and large-scale PV power stations. They withstand strong wind loads and ensure stable system operation in remote locations.
Infrastructure & Construction
Used extensively in bridge foundations, dock piers, and residential building footings. Our products replace traditional concrete footings, offering faster installation and reduced environmental impact during construction.
Marine & Offshore Engineering
Designed to resist seawater erosion and huge wave impacts, our studs are ideal for offshore platforms, oil drilling structures, and subway tunnels where corrosion resistance and seismic performance are critical.
Frequently Asked Questions
What is the minimum order quantity (MOQ) for custom threaded rods?
We support flexible ordering to accommodate both pilot projects and large-scale deployments. For standard items, we maintain a 10,000-ton inventory for rapid delivery. For custom specifications (OEM/ODM), please contact our sales team for MOQ details tailored to your specific design requirements.
How do you ensure corrosion resistance for overseas projects?
Our products strictly follow the GB/T 13912 standard for hot-dip galvanizing, ensuring a zinc layer thickness of not less than 85μm. This provides a salt spray test life of over 3,000 hours. For extremely corrosive environments (CX level), we can customize anti-corrosion schemes per EN-ISO-1461 standards.
What is the typical lead time for bulk orders?
Thanks to our automated production lines and intelligent scheduling, we can achieve "lightning delivery." Daily output capacity reaches 30,000 units. Standard orders ship quickly from inventory, while custom orders benefit from our efficient 25,000 sqm dual-base production system to meet tight project schedules.
Do you provide technical support for installation?
Yes, we offer 24/7 English technical consultation. For large-scale overseas projects, we can dispatch professional technicians for on-site guidance. We also provide detailed installation manuals specifying torque requirements and verticality checks to ensure optimal bearing capacity.
What warranty do you offer on your ground screws?
The main structure of our photovoltaic ground screws carries a 10-year warranty based on anti-corrosion performance. Core accessories like pile tips carry a 5-year warranty. In extremely corrosive environments, we can negotiate extended warranties up to 15 years with customized coating schemes.
