Jiangsu Aozheng Metal Products Co., Ltd. is a professional Expansion Anchor manufacturer and supplier based in China. Our 32,000-square-meter factory integrates automated cutting, stamping, CNC machining, and laser processing, allowing us to control quality from raw material to finished anchor. We supply expansion anchors in stainless steel, carbon steel, and low-alloy steel for construction, curtain wall, and precast concrete applications, with an annual production capacity of 8,000 tons.
Our expansion anchor range includes two-piece sleeve anchors, wedge anchors, and custom mechanical anchors. We support OEM/ODM projects, producing to your drawings or samples with consistent thread accuracy and expansion performance. Whether you need standard stock sizes or project-specific lengths and coatings, our engineering team configures the anchor to your substrate and load requirements.
We manufacture several expansion anchor types, each designed for a specific base material and installation method. The table below summarizes our available configurations and typical uses.
| Anchor Type | Material Options | Typical Applications |
|---|---|---|
| Two-piece sleeve anchor | Stainless steel (A2/A4), zinc-plated carbon steel | Concrete, brick, block; light to medium loads |
| Wedge anchor | Stainless steel, hot-dip galvanized carbon steel | Solid concrete; heavy structural fixing |
| Stud anchor | Zinc-plated, stainless steel | Concrete, stone; adjustable projection |
| Drop-in anchor | Carbon steel, stainless steel | Overhead and flush-mount applications |
We configure each expansion anchor based on the base material, edge distance, and required pull-out or shear values. Our in-house R&D team develops custom anchors from your drawings or samples, adjusting the expansion sleeve geometry, wedge angle, and thread length to match the installation torque and load specification.
For corrosive environments, we offer A4 stainless steel anchors with passivation. For indoor structural use, zinc-plated or hot-dip galvanized finishes provide cost-effective corrosion protection. We also supply anchors with hex nuts, washers, and thread protectors as complete kits.
Our factory operates a laboratory with a spectrometer, tension tester, and surface inspection equipment. Every production batch is checked for chemical composition, mechanical properties, and dimensional accuracy. We perform 99.99% inspection on finished anchors according to your requirements and international standards, ensuring consistent thread pitch and expansion sleeve integrity.
We hold ISO9001 certification and have passed BV, SGS, and TUV audits. Our quality system covers incoming raw material verification, in-process checks, and final pre-shipment inspection. For each order, we provide material test certificates and dimensional reports when requested.
Expansion anchors rely on correct hole diameter and depth for reliable grip. We supply installation data for each anchor size, including recommended drill bit diameter, minimum embedment depth, and tightening torque. Our anchors are designed for standard rotary hammer drilling; we do not supply drill bits unless specified.
For stone cladding and facade systems, we coordinate anchor selection with our Facade System Of Aluminum brackets to ensure compatible thread sizes and load transfer. In seismic zones, we recommend undercut anchors or additional mechanical locking; our team can advise on the appropriate expansion anchor type for your project.
We pack expansion anchors in cartons, pallets, or bulk bags depending on quantity and surface finish. Zinc-plated anchors receive anti-rust oil and protective wrapping. Stainless steel anchors are packed separately to avoid carbon steel contamination. Our location near Shanghai port enables efficient sea freight to global destinations.
To prepare a precise quotation and technical proposal, we need the following project data:
A wedge anchor uses a separate expansion clip that wedges against the concrete when the nut is tightened, providing high holding values in solid concrete. A sleeve anchor has a cylindrical sleeve that expands along its length, making it suitable for brick or block where the base material is less uniform. We supply both types and can recommend the right one based on your substrate.
Yes. We offer custom lengths, thread configurations, and coatings such as zinc plating, hot-dip galvanizing, and passivated stainless steel. Send us your drawing or specify the required dimensions, and we will produce a sample for your approval before mass production.
Yes, we provide material test certificates, dimensional inspection reports, and, if required, load test results from our in-house laboratory. Third-party testing can be arranged at an additional cost.
For standard sizes, our MOQ is typically 5,000 pieces. For custom designs, the MOQ depends on the complexity and material. We also supply samples for pre-production validation.
For seismic applications, we recommend using undercut anchors or anchors with mechanical interlock. Our standard expansion anchors can be designed with increased edge distances and deeper embedment to improve performance. We work with your structural engineer to select the appropriate anchor type.
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.
