While there is no direct ISO dimensional equivalent to DIN 3570, our U-bolts are manufactured to DIN 3570 dimensions, with mechanical properties strictly following ISO 898-1 and raw materials compliant with ISO 1035 .
1. Piping Systems & Infrastructure
Heavy-Duty Pipe Support
- Recommended: DN50 - DN500 (M10 to M24) | Grade 8.8 | Hot Dip Galvanized (HDG)
- Technical Insight: Essential for securing steel pipes to structural beams. The HDG coating ensures long-term integrity in outdoor or humid industrial corridors by preventing galvanic corrosion at contact points.
Gas & Fluid Transport Lines
- Recommended: Customized Sizes | Stainless Steel A4-80 (SS316) | Passivated
- Technical Insight: For pipelines carrying aggressive media, SS316 U-bolts provide excellent resistance to acid and chloride-induced stress corrosion cracking.
2. Marine & Offshore Engineering
Shipboard Conduit Fastening
- Recommended: M8 * 30 to M16 * 100 | Stainless Steel A4-80 | Polished
- Technical Insight: In high-salinity maritime environments, the polished finish minimizes salt accumulation, while the A4 grade prevents premature failure due to pitting.
Offshore Platform Railing & Piping
- Recommended: M12 to M20 | Grade 10.9 | Dacromet / Geomet
- Technical Insight: Combines high tensile strength with superior thin-layer anti-corrosion technology, ensuring structural stability without the risk of hydrogen embrittlement.
3. Communication & Utility Towers
Antenna & Cable Mounting
- Recommended: M10 * 60 / M12 * 80 | Grade 8.8 | Hot Dip Galvanized
- Technical Insight: U-bolts allow for secure clamping of cylindrical components to round or angular poles. The HDG layer is designed to withstand 20+ years of extreme weather exposure.
Power Transmission Cross-Arm Fastening
- Recommended: M16 * 150 / M20 * 200 | Grade 8.8 | HDG
- Technical Insight: Specifically engineered to handle the constant tension and wind-induced swaying of utility lines while maintaining torque.
4. Automotive & Heavy Machinery
Leaf Spring Suspension Assembly
- Recommended: M14 to M24 | Alloy Steel (Grade 10.9 / 12.9) | Zinc Phosphated
- Technical Insight: High-strength U-bolts are critical for clamping leaf spring packs. Phosphating provides a consistent torque-tension relationship to prevent loosening under heavy dynamic loads.
Exhaust System Mounting
- Recommended: M8 * 40 / M10 * 50 | Stainless Steel A2-70 (SS304)
- Technical Insight: Effectively manages high-temperature oxidation and thermal expansion cycles, ensuring the exhaust system remains aligned and leak-free.
