Wedge Anchor Manufacturers

Wedge Anchor Manufacturers – Engineered Fixings for Concrete and Stone

As a Wedge 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 professional Wedge Anchor manufacturer and supplier based in China, with a 32,000 m² production plant and an annual capacity of 8,000 tons of construction hardware. We design and produce wedge anchor bolts that deliver reliable expansion anchoring in cracked and uncracked concrete, as well as in natural stone and masonry. Our range covers standard mechanical wedge anchors and custom-engineered variants for facade support, structural steel connections, and heavy equipment fixing.

Every anchor we ship is manufactured in-house from stainless steel, carbon steel, or low-alloy steel, using automated cutting, stamping, CNC machining, and laser processing. This vertical integration lets us control thread accuracy, expansion clip geometry, and surface finish from raw material to final packaging. For procurement managers and project engineers, that means consistent load performance, traceable material certificates, and a single point of responsibility from quotation to delivery.

Product Range and Application Fit

Our wedge anchor line is built around the working point: the base material, the load direction, and the environmental exposure. We supply anchors for indoor dry conditions, outdoor atmospheric exposure, and highly corrosive coastal or industrial environments. The table below maps our standard configurations to typical project needs.

For facade and cladding projects, our stainless steel wedge anchors are often paired with our stainless steel facade systems and undercut anchoring systems. For general concrete fixing, we also offer mechanical expansion anchors and chemical anchors under the same anchor bolt family.

Engineering and Customization Approach

We do not treat wedge anchors as a commodity. Our engineering team reviews the base material grade, edge distance, spacing, and required load values before recommending a configuration. We can modify anchor length, thread pitch, clip design, and head type to match your installation tooling and structural drawings.

Customization is a core part of our factory capability. We develop tooling and production processes from customer drawings or samples, which allows us to produce anchors with non-standard diameters, extra-long embedment, or mixed material combinations. Our in-house R&D team also holds patents on several connection components, giving us the freedom to adjust geometry without third-party licensing delays.

Materials and Corrosion Protection

The anchor's service life depends on the correct material selection. We offer the following protection options:

• Zinc plating: Suitable for interior, dry environments where cost efficiency is a priority.
• Hot-dip galvanizing: For outdoor applications with moderate corrosion exposure, providing a thicker sacrificial layer.
• Stainless steel A2 (304): For atmospheric exposure, including urban and industrial settings.
• Stainless steel A4 (316): For coastal, marine, or chemically aggressive environments.

We also supply anchors in low-alloy steel for high-strength requirements where corrosion protection is applied separately. Our material certificates confirm chemical composition and mechanical properties, and we can provide test reports for batch traceability.

Quality Assurance and Testing

Quality control is integrated into every production step. We operate our own laboratory equipped with a spectrometer, tensile tester, and surface inspection tools. Each batch is checked for dimensional accuracy, thread fit, and hardness before packaging. For finished anchors, we perform 99.99% inspection according to customer requirements and international standards.

Our factory holds ISO9001 certification, and our products are exported to markets that require compliance with ASTM, DIN, or GB standards. We can provide test certificates for mechanical properties and, where requested, third-party inspection reports from SGS, BV, or TUV.

Installation and Maintenance Considerations

Wedge anchors are designed for simple installation: drill a hole to the specified diameter and depth, clean it, insert the anchor, and tighten the nut to the recommended torque. The expansion clip wedges against the concrete wall to create a mechanical interlock. We supply installation parameters with each quotation, including recommended torque values and minimum edge distances.

For maintenance, stainless steel anchors require no additional protection in most environments. Zinc-plated anchors should be inspected periodically in humid conditions. We can supply spare expansion clips or complete anchor kits for large projects, ensuring that on-site replacements match the original batch.

Information We Use to Configure Your Solution

To prepare an accurate quotation and technical proposal, we need the following project data. Providing this information upfront reduces revision cycles and ensures the anchor design matches your structural requirements.

• Base material type and grade (e.g., C20/25 concrete, stone, masonry)
• Required load values (tension, shear, or combined) and safety factors
• Environmental exposure class (interior, outdoor, coastal, chemical)
• Anchor diameter, embedment depth, and overall length
• Thread specification and head style (hex, countersunk, or custom)
• Quantity and packaging preference (bulk, boxed, or palletized)
• Any applicable standards or test requirements

Our sales engineers will confirm the technical parameters and provide a detailed drawing for approval before mass production.

Frequently Asked Questions

What is the difference between a wedge anchor and a sleeve anchor?

A wedge anchor uses a single expansion clip at the bottom that wedges against the concrete when the nut is tightened. It provides high load capacity and is ideal for solid concrete. Sleeve anchors have a thinner sleeve and are more suited to brick or block. We supply both types, but wedge anchors are our primary recommendation for structural concrete.

Can you produce wedge anchors with custom lengths or threads?

Yes. We regularly produce anchors with non-standard lengths, partial threads, or custom thread pitches. Send us your drawing or specify the required dimensions, and we will manufacture to your exact specification with full traceability.

What stainless steel grades do you offer for wedge anchors?

We offer A2 (304) and A4 (316) stainless steel as standard. For highly corrosive environments, A4 is recommended. We can also supply duplex stainless steel for specialized offshore projects.

Do you provide test certificates for your anchors?

Yes. Each batch can be supplied with a mill certificate, mechanical test report, and, if required, third-party inspection from SGS, BV, or TUV. We also maintain batch records for full traceability.

What is your typical lead time for custom wedge anchors?

Lead time depends on quantity and customization level. For standard sizes, we can ship within 2–3 weeks. For custom tooling, allow additional time for sample approval. We will confirm exact lead time with your order.

How do you package anchors for export?

We package anchors in cartons, wooden pallets, or steel crates depending on size and weight. Each package is labeled with product specifications and batch number. For large projects, we can provide palletization plans for efficient container loading.
