Introduction

Advanced Rear-Fixing Technology

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.

Benefits

Why Choose Our Undercut Anchor System

  • Stress-Free Mechanical Interlocking Connection

    Unlike expansion anchors, the undercut design distributes loads evenly through a form-fit connection, preventing cracking in brittle facade panels.

  • Superior Corrosion Resistance for Facades

    Manufactured from premium Grade 304 or 316 stainless steel to withstand harsh coastal environments and industrial pollutants.

  • High Seismic and Wind Load Performance

    Engineered to maintain structural integrity under dynamic loads, making them ideal for high-rise curtain wall applications.

  • Invisible Fastening for Aesthetic Excellence

    The rear-fixing method allows for clean, uninterrupted facade surfaces without visible clips or through-bolts.

Standard

Technical Compliance & Customization

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.

FAQS

Frequently Asked Questions

Common technical inquiries regarding the selection and installation of mechanical undercut anchors for facade engineering.

What materials are these anchors suitable for?
They are ideal for natural stone (granite, marble), porcelain stoneware, ceramic plates, and fiber cement panels, such as our granite cladding panels.
Do I need special tools for installation?
Yes, a dedicated undercut drilling machine and specialized diamond bits are required to create the conical hole geometry.
What is the difference between SS304 and SS316 anchors?
SS304 is standard for most urban environments, while SS316 offers superior molybdenum-enhanced resistance for coastal or high-pollution areas.
Can these be used for overhead applications?
Yes, the mechanical interlock provides a secure positive lock suitable for soffits and overhead cladding features.
What is the typical lead time for bulk orders?
Standard sizes are usually in stock; custom orders or large volumes typically ship within 2 to 4 weeks.
