PHL Heavy-duty Anchor

A mechanical expansion anchor with stable locking, high load capacity and good seismic performance, designed for heavy-duty post-installed anchoring in concrete.

Product Certification：
Tensile & shear/CE/Fatigue resistance

Scope of application：
Widely used for heavy structural fixing: curtain wall load-bearing brackets, steel structure supports, large equipment bases and pipe hangers.

Product Advantages

Even expansion, outstanding heavy-load capacity

A split, multi-slot expansion sleeve opens evenly in all directions when tightened, gripping a large area of the hole wall. Excellent pull-out and shear performance for heavy equipment bases, large steel structures and curtain wall mullions.

Integral sealing ring for controlled, leak-free installation

A red rubber limit ring precisely controls anchoring depth and blocks mortar and moisture from entering the hole. Reduces over-tightening and false locking, giving reliable anchoring on external walls and in damp underground conditions.

Countersunk design for concealed installation

The countersunk cone allows the head to sit flush within the component for a clean finished surface. Fully zinc-plated for corrosion protection, with resistance to vibration and loosening over long-term dynamic service.
