From Surface Elegance to Structural Safety: The Full Advantages of Expansion Anchors
Expansion anchors, also known as undercut anchors, are precision-engineered fasteners designed for construction and architectural applications that demand high load-bearing capacity and long-term reliability.
Ideal for installations involving marble panels, curtain walls, and tempered glass, these anchors offer both strength and aesthetics.
Expansion anchors work through a thread-in, pressure-free installation, eliminating stress on materials and ensuring secure attachment.
With superior tensile strength—often over 400 kg—they reduce the risk of cracks, preserve material integrity, and maintain visual appeal, especially in visible surfaces like stone or glass.
Unlike traditional wall plugs, expansion anchors with undercut designs minimize material pressure and drilling depth, while maximizing holding power.
They are trusted by façade engineers and professional installers across industries due to their reliability, safety, and cleaner aesthetics.
In curtain wall and cladding installations, undercut expansion anchors are the go-to solution for their unmatched pull-out resistance and ability to disperse stress evenly.
They allow secure, flush installations that keep external finishes neat and unbroken—ideal for high-end architectural designs.
When your project demands strength and precision, expansion anchors deliver.
These non-impact-installed anchors reduce the risk of panel damage and offer a clean, stress-free fastening system, making them perfect for stone, marble, glass, and other premium materials.
