High-Strength Undercut Mechanical Anchor

Product Advantages

Shallow Embedment, High Load Capacity

The mechanical key-locking effect of the Undercut Mechanical Anchor allows shallow embedment depths while maintaining exceptional pullout resistance and shear capacity—perfect for projects with limited substrate thickness (e.g., prefabricated buildings).

Near-Zero Expansion Stress

This anchor generates minimal expansion stress, enabling anchoring at minimal edge distances without damaging the substrate. It’s a top choice for edge-distance-sensitive projects like curtain wall mullion installations.

Immediate Full Load Capacity

No curing time is needed. After installation, the Undercut Mechanical Anchor delivers immediate full design load capacity, accelerating project timelines compared to chemical anchors.

Seismic & Fatigue Resistance

Certified to ACI 355.4 Category 3 (seismic compliance) and capable of withstanding 2 million fatigue cycles (EN 1992-4), this seismic-resistant undercut anchor performs reliably in dynamic environments (e.g., bridges, heavy equipment foundations).

Fire & Corrosion Protection

With fire resistance certified to EOTA TR 048 (90min/800°C), it meets strict fire safety standards. Surface treatments include electro zinc plating (zinc layer >5um for general use) and hot-dip zinc plating (zinc layer >45um for corrosive areas like coastal regions).

Detail Data

The Undercut Mechanical Anchor offers diverse models for varied project needs. Key specifications include:

Model M10/14*40: Drilling diameter 14mm, effective anchoring depth 40mm, drilling depth 45mm, screw length 80mm, fixture aperture 12mm, minimum bolt distance 16mm, minimum substrate thickness 80mm.

Model M12/18*80: Drilling diameter 18mm, effective anchoring depth 80mm, drilling depth 90mm, screw length 130mm, fixture aperture 14mm, minimum bolt distance 20mm, minimum substrate thickness 120mm.

Model M20/28*200: Drilling diameter 28mm, effective anchoring depth 200mm, drilling depth 220mm, screw length 300mm, fixture aperture 24mm, minimum bolt distance 32mm, minimum substrate thickness 290mm.

For C30 non-cracked concrete, Grade 8.8 variants offer tensile design values up to 58.8kN and shear design values up to 55.2kN; 316L(A4-80) stainless steel variants match these load capacities for corrosive environments.

Applications

Structural Reinforcement

Ideal for beam-column joint strengthening, seismic retrofitting, and skyscraper renovations. It retains over 85% pullout resistance in cracked concrete (vs. <50% for conventional anchors), complying with GB 50011 seismic codes.

Heavy Industrial Equipment

Secures power generator sets, precision machine tools, and chemical pipelines. Its high shear capacity (>50kN @ M20 per VDI 2230) suppresses vibration displacement, ensuring operational accuracy for compressors and hydraulic presses.

Transportation Infrastructure

Used in bridge expansion joints, tunnel segment repairs, and high-speed rail catenary mast foundations. Certified for -40°C to +80°C (EN 1992-4), it maintains 3D interlock through freeze-thaw cycles and train vibrations.

Energy & Power Engineering

Suitable for wind turbine grout zones, substation GIS equipment, and nuclear plant supports. With ISO 12944 C5M-compliant coatings, it resists corrosion and delivers 160kN pullout strength @ M24 (per IEC 61400-6).
