A2-70 Stainless Steel U-Bolt Anchor | Embedded U-Bolt for Construction, Photovoltaics, and Piping

   

The Key Advantages of A2-70 Material Stainless U Bolts

① Superior Corrosion Resistance

Made of 304 stainless steel, it withstands humidity, acidic/alkaline conditions, and mild salt spray; offers a rust-free lifespan of over 10 years in outdoor or chemical processing environments—5 to 10 times that of standard carbon steel. Features a passivation finish (no plating) to eliminate the risk of coating delamination, making it suitable for food, pharmaceutical, and sanitary-grade equipment applications.

② High-Strength Pull-Out Resistance

Tensile strength of 700 MPa and pull-out resistance ≥15 kN; pull-out performance increases by over 40% when the embedment depth is 15–20 times the bolt diameter. Formed via integral hot bending with no welded weak points; offers excellent vibration and fatigue resistance, ideal for long-term equipment operation.

③ Versatile Application

Wraparound design resists both horizontal shear forces and vertical displacement, providing strong clamping force and easy installation. Customizable length, bending radius, and thread specifications to meet non-standard engineering requirements.

④ Long-Term Cost-Effectiveness

While the initial purchase price is slightly higher than carbon steel, maintenance costs are reduced by 80%; eliminates the need for frequent replacement, resulting in lower total cost of ownership over time. Costs 30%–50% less than A4-80 (316) stainless steel while meeting the needs of the vast majority of environments that do not involve extreme corrosion.
