The manufacturer of fasteners (anchors / rods / bolts / screws...) and fixing elements

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

Short Description:

A2-70 grade U-bolts have become essential fasteners across the construction, industrial, and new energy sectors, thanks to the corrosion resistance of 304 stainless steel, their high tensile strength (700 MPa), and their versatility across diverse applications. Whether for new construction, equipment upgrades, or the renovation of existing projects, selecting A2-70 U-bolts ensures structural safety and stability while reducing long-term maintenance costs, making them a highly cost-effective choice for engineering procurement.

    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.
