Handan Yongnian District Dongshuo Fastener Manufacturing Co., Ltd. was established in 2015. Over the last decade, we have evolved from a local manufacturer into a Global Leading U Bolt Supplier. Located in the fastener hub of Handan, Hebei, China, our facility spans thousands of square meters, housing the latest in cold-forging and hot-bending technology.
Our commitment is rooted in providing high-quality fastener products and providing customers with comprehensive solutions in various industries. As a reputable fastener manufacturer, we have advanced production equipment and a professional technical team to meet our customers' needs for different types of fasteners.
In the complex landscape of global industrial procurement, a U-Bolt is not just a piece of bent metal; it is a critical component for structural safety. Global enterprises are shifting their procurement strategies to focus on Total Cost of Ownership (TCO) rather than just unit price.
Whether it is Carbon Steel (Q235/35#/45#), Alloy Steel, or Stainless Steel (SUS304/316), the metallurgical purity determines the stress-corrosion cracking resistance.
Beyond standard galvanization, we offer Hot-Dip Galvanizing (HDG), Dacromet, and Geomet coatings to ensure 1000+ hours of salt spray resistance for offshore environments.
Adherence to DIN 3570, ASME B18.31.5, or custom blueprints is non-negotiable. Our CNC threading ensures a perfect fit every time, reducing installation time.
Our fasteners are deployed in some of the world's most demanding sectors. We don't just sell bolts; we provide the backbone for critical infrastructure.
Bridge construction, highway signage, and pipeline support systems. Our U-Bolts secure large-diameter pipes under high vibration and thermal expansion cycles.
Solar tracker mounting systems require high-tensile fasteners that can withstand UV exposure and varying wind loads. Dongshuo provides specialized UV-resistant coatings.
Seawater is the ultimate test of corrosion resistance. Our 316 Stainless Steel U-bolts are the industry standard for ship rigging and offshore oil rigs.
The global fastener industry is entering a "Smart & Green" era. At Dongshuo, our technical roadmap focuses on three core pillars:
As a Global Leading U Bolt Supplier, we are transitioning from standard hardware manufacturing to Advanced Engineering Partnership, providing co-design services for bespoke fastening challenges.
Navigating international trade requires more than just a good product. Dongshuo provides localized support for markets in North America, Europe, Southeast Asia, and the Middle East.
