Precast Concrete Embedded Parts & Accessories Manufacturers

Precast Concrete Embedded Parts & Accessories from a Direct Manufacturer

Jiangsu Aozheng Metal Products Co., Ltd. is a China-based manufacturer and supplier of precast concrete embedded parts and accessories, with a 32,000 m² production plant and an annual capacity of 8,000 tons of construction hardware. We produce lifting flat anchors, tube anchors, cast-in anchors for metro and rail projects, and curtain wall embedded parts, all engineered to transfer loads safely during lifting, transport, and installation of precast concrete elements.

Our factory integrates automated cutting, stamping, welding, CNC machining, and laser processing, allowing us to deliver both standard and custom configurations in stainless steel, aluminum alloy, carbon steel, and low alloy steel. We supply directly to precast plants, facade contractors, and engineering teams worldwide, including markets in the US, Europe, the Middle East, and Asia.

Product Range and Application Fit

Each product family in our Precast Concrete Embedded Parts & Accessories Manufacturers range is designed for a specific stage of precast handling and structural connection. The table below outlines the main types and where they are used.

Engineering and Customization

We work from your drawings or samples to develop anchors that match your precast element weight, concrete strength, and lifting geometry. Our in-house R&D team and mold/tooling shop allow us to produce non-standard shapes, sizes, and materials without relying on outside suppliers.

• Custom load ratings: we calculate anchor capacity based on concrete grade, edge distance, and lifting angle.
• Material selection: stainless steel (304/316) for corrosive environments, carbon steel with hot-dip galvanizing for cost-effective projects, and low alloy steel for high-strength needs.
• Surface finishing: passivation, galvanizing, or powder coating as specified.
• Packaging: palletized or in crates with clear labeling for precast yard handling.

Quality Assurance and Testing

We maintain strict in-process inspection and final testing in our own laboratory. Our equipment includes spectrometers, tensile testers, and surface testers to verify chemical composition and mechanical properties. For each batch, we can provide material certificates and dimensional inspection reports.

We also hold ISO9001 and have factory audits by BV, SGS, and TUV, confirming our quality management system meets international standards.

Project Support and Documentation

Our team supports you from sample approval to delivery. We provide technical datasheets, installation instructions, and lifting load charts. For large projects, we coordinate production schedules and shipping to meet your site deadlines.

Information We Use to Configure Your Solution

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

• Precast element type, dimensions, and weight
• Concrete compressive strength and cover thickness
• Lifting method (crane, spreader beam, tilt-up) and number of anchors
• Required working load and safety factor
• Environmental exposure (indoor, coastal, chemical)
• Material and finish preferences
• Target quantity and delivery schedule

Frequently Asked Questions

What is the difference between a lifting flat anchor and a tube anchor?

Lifting flat anchors are flat steel plates with a hole or loop, embedded in the concrete surface for lifting with a clutch or hook. Tube anchors are cylindrical sockets with a threaded or crimped end, allowing a lifting bolt to be screwed in. The choice depends on the concrete thickness and the lifting system you use.

Can you produce anchors with custom load ratings?

Yes. We regularly produce custom anchors based on the required working load, concrete grade, and edge distances. Our engineers can recommend the appropriate anchor type and size for your specific precast element.

What materials are available for embedded parts?

We offer stainless steel (304, 316), aluminum alloy, carbon steel, and low alloy steel. For carbon steel, we provide hot-dip galvanizing or other protective coatings to meet corrosion resistance requirements.

Do you supply anchors for metro and rail projects?

Yes, our cast-in anchors for metro are specifically designed for tunnel segments, rail fastenings, and heavy infrastructure. They are made from high-strength materials and undergo rigorous quality testing.

How do you ensure the quality of mass-produced anchors?

We perform 99.99% inspection on finished products, including dimensional checks and material verification. Our laboratory is equipped with spectrometers and tensile testers, and we can provide batch test certificates upon request.
