Our Mechanical Undercut Anchor Bolts are designed for the invisible attachment of natural stone, ceramic tiles, and high-pressure laminates. By creating a positive mechanical interlock within a pre-drilled conical hole, these anchors ensure maximum safety without inducing expansion stress in the cladding material.
Unlike expansion anchors, the undercut design distributes loads evenly through a form-fit connection, preventing cracking in brittle facade panels.
Manufactured from premium Grade 304 or 316 stainless steel to withstand harsh coastal environments and industrial pollutants.
Engineered to maintain structural integrity under dynamic loads, making them ideal for high-rise curtain wall applications.
The rear-fixing method allows for clean, uninterrupted facade surfaces without visible clips or through-bolts.
Our anchor bolts are available in various lengths and diameters to accommodate panel thicknesses ranging from 8mm to 40mm. We offer specialized sleeves and spacers to ensure precise alignment across the entire facade grid.
All hardware undergoes rigorous pull-out testing and salt spray analysis. Custom dimensions and material grades can be manufactured to meet specific project engineering requirements and international building codes.
