Lifting Spread Anchor Manufacturers

Lifting Spread Anchor Manufacturers

As a Lifting Spread Anchor Manufacturers and supplier, Jiangsu Aozheng Metal Products Co., Ltd. produces heavy-duty lifting anchors engineered for safe and efficient handling of precast concrete elements. Our range includes standard spread anchors, sandwich anchors, and erection anchors, all manufactured from special-quality flat steel and designed to integrate with ring clutch systems.

With a 32,000 m² factory and an annual capacity of 8,000 tons, we support projects from single-element prototypes to large-scale precast production. Our in-house R&D and production capabilities allow us to deliver custom lengths, load ratings, and finishes that match your specific concrete element geometry and lifting plan.

Our Lifting Anchor Range

We supply three main anchor types, each suited to different precast handling scenarios:

• Standard Spread Anchor – For general lifting of walls, columns, and beams. The anchor foot spreads inside the concrete to provide high pull-out resistance.
• Sandwich Anchor – Designed for elements with insulation layers, such as sandwich panels. The anchor bridges the insulation while maintaining structural integrity.
• Erection Anchor – Used for temporary support during erection, allowing safe positioning and alignment of precast components.

Engineering and Customization

Each anchor is manufactured from special-quality flat steel, with the anchor foot shape tailored to the specific anchor type. The anchor head features a precisely machined hole that accepts the locking bolt of a ring clutch, ensuring a secure connection during lifting. Every anchor carries a clearly visible, stamped manufacturer's designation that includes the product and system designation, anchor type, length, and load rating.

We offer customization in:

• Anchor length and width to suit element thickness and edge distances.
• Material grade – stainless steel for corrosive environments or carbon steel with protective coating.
• Load capacity – engineered to match your required working load limit (WLL).
• Foot geometry – standard or special shapes for optimized concrete engagement.

Quality Assurance and Testing

Our factory operates under strict quality management systems, with in-house testing capabilities including a spectrometer for material verification and a tension tester for mechanical property validation. We conduct inspections at every production stage, and finished anchors undergo 99.99% inspection to ensure dimensional accuracy and surface integrity.

We can provide material certificates and test reports to support your project documentation requirements.

Application Fit and Installation

Lifting spread anchors are embedded in precast concrete elements during casting. They are used with ring clutches and crane systems to lift, transport, and erect elements safely. Proper anchor selection depends on:

• Element weight and dimensions.
• Concrete strength and curing conditions.
• Lifting angle and number of anchors used.
• Environmental exposure (indoor, outdoor, marine).

We provide technical guidance on anchor positioning and minimum edge distances to ensure optimal performance.

Information We Use to Configure Your Solution

To prepare a precise quotation and engineering proposal, we need the following project information:

Maintenance and Serviceability

Lifting anchors are single-use or reusable depending on the type. We recommend inspecting anchors before each use for deformation or damage. Our team can provide replacement parts and technical support for the lifetime of your project.

Packaging and Delivery

We package anchors in sturdy crates or pallets to prevent damage during transit. Our location near Shanghai port ensures efficient sea freight to global destinations. We can also arrange air freight for urgent orders.

FAQs

What is the difference between a lifting spread anchor and a lifting socket?

Lifting spread anchors are embedded in concrete and have a flat head with a hole for a ring clutch, while lifting sockets are typically threaded inserts that accept a lifting bolt. Spread anchors are often used for heavier loads and provide a larger load-bearing area.

Can you provide anchors with custom load ratings?

Yes, we can engineer anchors to meet specific working load limits. Provide us with the required load and element details, and we will design the anchor geometry and material accordingly.

What materials are available for lifting anchors?

We manufacture from special-quality flat steel, including stainless steel grades like 304 and 316 for corrosion resistance, and carbon steel with optional galvanizing or other coatings.

Do you provide installation instructions?

Yes, we supply detailed installation guidelines with each order, including positioning, edge distances, and lifting procedures to ensure safe use.

How do you ensure the quality of your anchors?

We conduct in-house material testing and dimensional inspections at every production stage. Each anchor is marked with traceability information, and we can provide test certificates upon request.
