Ningyuan Fastener
Explore our industrial-grade structural components engineered for heavy-duty assemblies, concrete embedding, and advanced PV mounting infrastructures.
Handan Ningyuan Fastener Manufacturing Co., Ltd. (formerly Jin Langtao), founded in 2005, is located in Handan Yongnian, the hometown of Taiji and the fastener capital, which is well-known at home and abroad. Since our inception, we have adhered to the enterprise philosophy that development is the direction and hard work is the truth.
Through over 18 years of continuous efforts, structural innovation, and technological development, we have transformed from high-end fastener manufacturing and photovoltaic mounting accessory production into a well-known modern enterprise. We actively adjusted our organizational structure, forming a research and development department as the base, the production department as the central hub, and the sales department as a breakthrough team.
A comprehensive overview of our compliance frameworks, testing credentials, and technical installation methodologies.
Focused on the structural thread insert industry, achieving an annual output of 60 million+ pieces. Authorized Municipal Fastener Research Center.
Certified weapons & equipment manufacturing clearances, ISO9001 quality system, RoHS EU testing, and GB/T30512 automotive banned substances compliance.
We provide free physical samples of regular fastener lines, T-bolts, and hex screws for evaluation, checking structural specifications beforehand.
Our in-house engineers deliver free load calculations, joint styling analysis, and detailed on-site installation guidelines for seismic supports.
In high-load construction, infrastructure engineering, and industrial assemblies, structural screws serve as critical load-bearing connections. Unlike standard wood or drywall screws, structural screws are engineered with precision metallurgies and custom thread profiles to handle high shear stresses, massive tensile loads, and long-term dynamic forces. They are key elements in modern pre-fabricated timber construction, heavy steel detailing, solar photovoltaic rack mount systems, and municipal seismic bracing configurations.
The mechanical integrity of structural fasteners depends on material selection and heat treatment precision. Ningyuan leverages medium-carbon steel alloys (such as SAE 1022, Boron steel, and medium carbon steels) combined with continuous mesh belt furnace heat treatments. This thermal cycle achieves optimal core hardness while preventing case-hardening embrittlement. This balanced mechanical state provides:
"Structural connections require fasteners that yield before failure under extreme load events (like earthquakes or typhoons). Our mechanical design principles prioritize ductility alongside raw tensile strength."
Yongnian in Handan, Hebei Province, stands as the center of global fastener manufacturing. This localization offers major benefits for international B2B buyers:
Structural screws are frequently exposed to harsh outdoor settings, including coastal marine dampness, industrial chemical fumes, and agricultural ammonia. We offer targeted protective finishes:
Ningyuan's product selection covers key structural areas:
Ningyuan's primary structural product lines, from self-drilling metal screws to specialized heavy-duty anchor configurations.
How Ningyuan processes raw materials into qualified structural fasteners within our 20,000 square meter factory.
Raw steel rod is chemically descaled, sized, and cold drawn to the target outer wire diameter under tight dimension tolerances.
High-speed cold headers form screw head details (hex flange, pan, countersunk) and structural shank properties without heat defects.
High-precision thread rollers form uniform threads, retaining continuous grain structures for high shear strength.
Screws undergo carbonitriding or hardening, followed by hot-dip galvanizing or zinc plating to resist environmental wear.
Where our structural screws, bolts, and brackets are utilized globally by civil contractors and solar EPCs.
Our ongoing commitment to international quality protocols, supply transparency, and technical innovations.
Handan Ningyuan has established a complete Quality Management System, operating in compliance with ISO 9001:2015 guidelines. Every production batch of structural wood and metal screws is subjected to torque testing, metallographic grain structure analyses, core and surface hardness profiling (Vickers/Rockwell), and zinc coating thickness validation.
Our chemical lab verifies raw materials against strict standards, including the GB/T30512 automotive banned substances list and EU 2000/53/EC ELV directives, preventing toxic material contamination in industrial builds.
Heavy-duty hardware, connecting nuts, and specialized brackets for construction framing and industrial pipe installation.
Expert engineering insights regarding product specification, order logistics, surface treatments, and sourcing standards.
