Explore our premium selection of certified anchor bolts, automotive connectors, and corrosion-resistant hardware engineered for extreme industrial environments.
Backed by nearly two decades of metallurgical mastery, VLC delivers exceptional manufacturing capacity and rigorous quality assurance worldwide.
As a preeminent bolts and screws manufacturer in China, VLC has witnessed firsthand the paradigm shift in global engineering specifications. Modern structural integrity, offshore wind energy installations, high-speed rail networks, and automotive lightweighting demand fasteners that endure punishing operational environments without failure. Coated and surface-treated fasteners have transitioned from optional enhancements to mandatory requirements in international structural design codes.
With an annual output exceeding 10,000 tons of high-grade bolts, studs, and specialized screws—particularly hex bolts, structural structural fasteners, and high-tensile studs—VLC has anchored its operational philosophy in customer-centric reliability. Since our inception in 2006, our leadership has championed strict metallurgical compliance, advanced electroplating, hot-dip galvanizing, and specialized anti-corrosion barrier technologies that extend service life by up to 300% in marine and chemical processing applications.
Excellence in coated fastener manufacturing requires complete vertical integration of machining, heat treatment, and surface coating processes. VLC operates state-of-the-art production facilities equipped with multi-axis CNC machinery, high-speed automatic lathes, precision cold-forging units, and advanced threading centers.
Discover our heavy-duty bridge construction fasteners, scaffolding clamps, brass alloys, and weatherproof outdoor hardware.
The next decade in fastener engineering will be defined by smart coatings, nanotechnology barrier layers, and IoT-enabled embedded sensors. As a top-tier exporter, VLC is actively investing in eco-friendly trivalent passivations, zinc-flake coating lines compliant with strict EU environmental directives (RoHS and REACH), and cryogenic treatment protocols to enhance tensile performance under sub-zero operating conditions.
Our commitment to R&D ensures that global infrastructure developers, renewable energy EPC contractors, and automotive tier-1 suppliers receive fasteners engineered to outlast the operational lifespan of the core assemblies they secure.
VLC provides comprehensive B2B supply chain solutions tailored to heavy industries. Whether supplying EN14399 structural assemblies for European megastructures, specialized high-strength anchor bolts for Asian metro transit systems, or custom brass connectors for precision electronics, our engineering team offers full lifecycle support—from metallurgical consultation and custom prototyping to mass production and logistics management.
By maintaining stringent adherence to international standards (ISO, DIN, ASTM, JIS), we eliminate supply chain friction and guarantee uncompromising quality for global importers.
Expert answers regarding our manufacturing capabilities, coating technologies, and international export procedures.
We offer a comprehensive range of advanced surface treatments, including Hot-Dip Galvanizing (HDG), Zinc Electroplating (Clear, Yellow, Black), Zinc-Flake coatings (Geomet/Dacromet), Nickel plating, and Passivated Stainless Steel finishes to match specific corrosion resistance requirements.
VLC maintains an annual manufacturing output exceeding 10,000 tons of industrial bolts, structural studs, anchor fasteners, and custom-machined components across our advanced production facilities.
Yes, all our products are manufactured in strict compliance with ISO, DIN, ASTM, EN14399, and JIS standards. Every production batch undergoes rigorous spectral analysis, tensile testing, and salt-spray corrosion trials prior to shipment.
Absolutely. With extensive experience in CNC machining, automatic lathe operations, and cold forging, we specialize in producing custom non-standard fasteners tailored precisely to client specifications and project blueprints.
