Explore our export-grade line of industrial metal anchorage systems, structural steel segments, and specialized self-drilling fastener applications.
Within structural civil engineering and mechanical design, mechanical anchors and expansion screws play a critical role in load transfers. As engineering projects scale up to resist higher wind pressures and dynamic seismic forces, selecting the correct anchoring components is crucial for safety and longevity.
Chinese fastener exporters have transitioned from simple high-volume manufacturing to advanced technological R&D. Driven by structural requirements in the solar photovoltaic industry, high-load underground utility projects, and seismic building frames, manufacturers like Handan Ningyuan Fastener Co., Ltd. offer high-performance fastening solutions designed to meet international standards.
Handan Ningyuan Fastener Manufacturing Co., Ltd. (formerly Jin Langtao), founded in 2005, is located in Handan Yongnian, widely recognized as a major manufacturing hub for high-quality fasteners. For over 18 years, the company has operated under a simple guiding principle: development is our goal, and quality engineering is our driver. We focus on producing high-grade structural fasteners and photovoltaic installation brackets, growing into a modern manufacturing enterprise.
In 2016, we expanded our organizational structure, integrating our design department with high-capacity production lines. The company currently employs 66 specialists, including 6 dedicated mechanical testing engineers and 15 senior operations specialists. This structural alignment allows us to supply complete fastening systems directly to international buyers.
Providing high-durability anchor bolts and support frameworks engineered to perform reliably across demanding industrial applications.
Wind-resistant steel profiles, C-shaped steel supports, and zinc-coated anchor systems designed to secure ground-mount solar arrays in high-wind regions.
Seismic support structures, corner joints, and V-shaped reinforcement components designed to absorb lateral forces and protect mechanical systems during seismic events.
Heavy-duty steel pipe support systems and connection hardware built to resist corrosion in high-humidity municipal service tunnels.
High-tensile carriage bolts, countersunk bolts, and custom industrial anchor components designed to carry heavy static loads in steel structural assemblies.
Our fasteners are manufactured using select carbon steel (Grades 4.8, 8.8, 10.9, 12.9) and high-alloy stainless steels. Because environmental conditions vary, we offer customized surface finishes to ensure long-term performance.
Our manufacturing and inspection processes align with industry standards to support international project approvals.
Ningyuan Fasteners: Audited and certified to ISO 9001, RoHS, and EU ELV standards.
Our core selection of self-drilling screws, heavy-duty wedge anchor bolts, connecting nuts, and industrial brackets.
High-performance self-drilling screws featuring a low-profile truss head, designed to attach sheet metal to metal or wood frameworks without pre-drilling.

Our heavy-duty carriage bolts and structural connection plates are designed to maintain clamping force in high-load structural steel frames.
Ground screw anchors and hot-dip galvanized base connectors support structural stability on solar projects built over uneven terrain.
Underground pipe galleries use our heavy-duty beam clamps and adjustable structural channels to secure utility runs under constant loading.
Our structural seismic brackets and connecting components help keep overhead utility runs secure during building movement.
Addressing core technical questions from design engineers, procurement specialists, and installers.
Wedge anchors use mechanical friction to secure loads. When you torque the bolt, the tapered end draws upward into the expansion sleeve, pressing it against the walls of the pre-drilled hole. This expansion mechanical lock transfers both shear and tensile forces to the surrounding concrete matrix.
Electro-galvanizing usually creates a thin protective layer of 5μm to 12μm, which is suitable for indoor use. Hot-Dip Galvanizing immersion forms a thicker metallurgical zinc-iron layer (often 50μm to 85μm). This provides barrier protection and sacrificial protection in outdoor C3 to C5 corrosive environments.
Standard embedment depth is typically at least four times the nominal diameter of the bolt. However, structural calculations must account for the actual design load, the compressive strength of the concrete, and the minimum spacing between adjacent anchors to prevent concrete breakout failures.
We maintain ISO 9001 compliance, check raw materials by batch, and use automated forming and thread-rolling machinery. Finished batches undergo tensile, shear, and coating thickness testing to verify performance before delivery.
