Product Details

Our Hot-Dip Galvanized DIN 3570 U-bolts are engineered to withstand the harshest conditions while providing a secure, long-lasting clamp.

• Superior Hot-Dip Galvanized (HDG) Finish: This is not a standard plating. The HDG process involves immersing the entire carbon steel U-bolt in a bath of molten zinc. This creates a thick, durable, and metallurgically bonded coating that is far superior to standard zinc plating. The coating provides both barrier and sacrificial protection, meaning it will corrode preferentially to protect the steel base, even if scratched. This makes it the ideal choice for long-term outdoor exposure and aggressive industrial atmospheres.
• DIN 3570 Standard for Precise Fit: Manufactured in strict accordance with DIN 3570, these U-bolts are dimensionally standardized to fit specific nominal pipe sizes. This ensures a perfect, secure grip around pipes and tubes, eliminating guesswork and guaranteeing reliable installation.
• High-Strength Carbon Steel Construction: The core of the U-bolt is made from high-quality carbon steel, available in property classes such as 4.8, 8.8, and 10.9. This provides the necessary tensile strength and load-bearing capacity for heavy-duty structural and industrial clamping tasks.
• Factory-Direct Customization: As the manufacturer, we offer complete customization services. We can produce U-bolts in non-standard lengths, thread specifications, and dimensions to meet your unique project requirements, all while maintaining competitive factory-direct pricing.

Product Features

Our HDG U-bolts are chosen for their exceptional performance, driven by these key features.

• Maximum Corrosion Protection: The thick, metallurgically bonded zinc coating provides decades of protection against rust and corrosion, significantly outperforming electro-galvanizing (zinc plating).
• Structural Strength and Durability: Made from high-strength carbon steel, these U-bolts are designed to handle heavy loads and provide robust, long-term structural support.
• Factory-Direct Value and Flexibility: By eliminating middlemen, we offer the most competitive pricing. Our custom manufacturing capabilities ensure you get the exact fastener you need for your application.
• Standardized for Reliability: Compliance with the DIN 3570 standard guarantees dimensional accuracy and a dependable fit for all standard pipe sizes.
• Complete Fastening Solution: Typically supplied with matching HDG nuts, our U-bolts are ready for immediate installation, ensuring consistent corrosion protection across the entire assembly.

Product Applications

The superior durability of Hot-Dip Galvanized DIN 3570 U-bolts makes them essential for a wide range of demanding applications.

• Outdoor Infrastructure: Ideal for securing pipes, conduits, and structural elements on bridges, communication towers, highway signages, and utility poles.
• Industrial and Chemical Plants: Used extensively in refineries, water treatment facilities, and processing plants where exposure to chemicals and moisture is constant.
• Construction and Civil Engineering: Perfect for anchoring pipe runs, supporting structural beams, and other permanent installations exposed to the elements.
• Marine and Coastal Environments: The best choice for use in docks, piers, shipbuilding, and coastal construction due to its excellent resistance to saltwater corrosion.
• Agricultural Sector: Used for assembling irrigation systems, mounting equipment, and constructing durable fencing and enclosures that must withstand outdoor conditions.
