READ MOREProducts / Undercut Anchoring System / Aseismic-Undercut Anchor
As a Aseismic-Undercut Anchor Manufacturers, we match product configuration to the application, operating limits, interfaces and acceptance criteria defined for each project.
Jiangsu Aozheng Metal Products Co., Ltd. is a China-based Aseismic-Undercut Anchor manufacturer specializing in high-load anchoring systems for concrete and masonry. Our aseismic undercut anchors are engineered to provide reliable performance in seismic zones, with a design that resists pullout and accommodates dynamic loads. We supply a complete range of undercut anchors, including knocking and screw-in types, for facade systems, structural connections, and precast concrete applications.
With a 32,000 m² production facility and an annual capacity of 8,000 tons, we combine automated cutting, stamping, CNC machining, and laser processing to deliver consistent quality. Our factory integrates raw material forming and mechanical processing, ensuring precise tolerances and traceability for every batch. As a direct supplier, we offer OEM/ODM customization, competitive pricing, and technical support from initial design to site installation.
Our aseismic undercut anchors are available in several configurations to match different substrate conditions and load requirements. Each type uses an undercut drilling technique that creates a mechanical interlock, ideal for cracked concrete and seismic zones.
| Anchor Type | Design Features | Typical Applications |
|---|---|---|
| Knocking-Undercut Anchor | Hammer-set expansion, conical screw, plastic sleeve | Facade brackets, handrails, steel connections |
| Screw-In-Undercut Anchor | Torque-controlled expansion, removable | Structural steel, seismic retrofits, heavy machinery |
| Aseismic-Undercut Anchor | Enhanced energy dissipation, high load capacity | Earthquake-resistant structures, precast panels |
We also supply the corresponding drilling machines and accessories to ensure correct installation. For projects requiring cast-in solutions, our undercut anchoring system integrates with our Undercut Anchoring System range, including channels and T-bolts.
Our R&D team has focused on material science and structural design to improve seismic performance. We use high-strength stainless steel, carbon steel, and low-alloy steel, with surface treatments like galvanizing or electroplating for corrosion resistance. The anchor geometry is optimized to create an undercut that transfers loads effectively, even in cracked concrete.
We offer custom lengths, diameters, and thread configurations based on your drawings or samples. Our in-house tooling team can develop molds for non-standard shapes, and we provide samples for pre-production validation.
Every production stage is inspected, and finished anchors undergo rigorous testing in our laboratory. We perform tensile, fatigue, and corrosion resistance tests, as well as seismic simulation to verify performance under dynamic loads. Our quality system is certified to ISO9001, and we can provide test reports and material certificates upon request.
Correct installation is critical for undercut anchors. We provide detailed installation instructions and recommend using our drilling machines to achieve the precise undercut geometry. Our technical team is available to review your application, calculate anchor spacing and edge distances, and recommend the appropriate anchor size and grade.
To prepare a precise quotation and technical proposal, we need the following project details:
We package anchors in cartons or pallets with protective coating to prevent damage during transit. Our location near Shanghai port ensures efficient sea freight to global destinations, and we can arrange air freight for urgent orders.
Aseismic undercut anchors are designed to withstand dynamic loads from earthquakes. They feature enhanced energy dissipation mechanisms and are tested under simulated seismic conditions to ensure they maintain their grip in cracked concrete.
Yes, our undercut anchors are suitable for cracked concrete. The undercut mechanism provides a positive mechanical interlock that remains effective even when cracks develop.
We manufacture anchors from stainless steel (e.g., A4), carbon steel with hot-dip galvanizing, and low-alloy steel. Material selection depends on corrosion resistance and strength requirements.
Yes, we supply drilling machines and setting tools specifically designed for our undercut anchors to ensure accurate installation and optimal performance.
Lead time depends on order quantity and customization. Standard sizes are usually shipped within 2-3 weeks after deposit, while custom orders may take longer. We confirm exact schedules with each quotation.
Our portfolio also includes Products for applications with different operating ranges, interfaces or integration requirements.
We will wholeheartedly provide you with high quality products, reasonable price, on-time delivery and attentive service.
