Our flat end lifting socket is purpose-built for secure lifting of precast concrete elements. Made from premium alloy steel, it offers outstanding strength, durability, and corrosion resistance. The flattened end with a reinforced rebar hole ensures better force distribution, while the threaded end allows firm connection to lifting devices. HULK Metal's CE and ISO 9001 certifications guarantee consistent performance and safety in every lifting application.
A flat end lifting socket, also known as a flat end lifting insert, is a critical lifting accessory for precast concrete construction. It is manufactured from high-performance alloy steel tubes for maximum load capacity and long-term reliability.
One end is flattened and precisely machined with a hole, allowing rebar insertion. This design ensures that lifting forces are distributed evenly within the concrete element, enhancing grip and preventing pull-out during lifting. The other end features precision threading, enabling secure connection with lifting loops, hoist rings, or similar lifting devices.
HULK Metal's flat end lifting sockets comply with CE and ISO 9001 standards, ensuring superior tensile and shear strength. They are suitable for lifting panels, beams, and other precast components in demanding environments. Consistent quality control and rigorous testing make these lifting inserts a dependable choice for safe and efficient handling on construction sites.
The flat end lifting socket works by transferring lifting forces from the connected device into the reinforced concrete element through rebar reinforcement. When lifting, the lifting loop or hoist ring is screwed securely into the threaded end. The flattened end, embedded in the concrete with rebar passing through its hole, distributes the load evenly across the concrete mass, minimizing stress concentration. This prevents the socket from slipping or damaging the concrete during lifting.
Proper alignment, correct embedment depth, and sufficient concrete cover are essential for safe use. When installed and used correctly, flat end lifting sockets provide a reliable and efficient method for moving heavy precast elements without compromising structural integrity.
Flat end lifting sockets are widely used in the production and installation of precast concrete components. They are ideal for lifting panels, beams, walls, stairs, columns, and other structural elements. Their design makes them suitable for applications where lifting points must remain secure and hidden after installation. They are extensively used in commercial buildings, infrastructure projects, and residential construction. In precast factories, these sockets streamline handling, reduce setup time, and improve overall lifting safety. The combination of high strength, compact design, and compatibility with multiple lifting devices makes them an essential tool for efficient concrete element handling.
HULK Metal's flat end lifting sockets offer several advantages over conventional lifting inserts. The flattened rebar hole design ensures optimal load transfer and prevents slippage during lifting. Manufactured from premium alloy steel, they deliver higher tensile and shear strength for demanding applications. Precision threading allows smooth and secure connection with various lifting devices, improving installation efficiency. Our sockets are coated for enhanced corrosion resistance, ensuring durability even in harsh environments. With CE and ISO 9001 certifications, every product meets strict safety and performance standards. Combined with shorter production cycles and global delivery capability, they are a reliable choice for large-scale projects.
We start by thoroughly reviewing your technical drawings, load requirements, and project timelines. Our engineering team communicates with you to confirm every detail, ensuring the design, material choice, and production plan meet your lifting needs precisely.
We procure high-performance alloy steel from trusted suppliers. Before production, materials undergo strict composition checks, hardness testing, and dimensional inspection to ensure they meet CE and ISO standards for strength, durability, and corrosion resistance.
Steel tubes are cut to precise lengths using advanced cutting equipment. Each blank is measured and inspected to ensure uniformity, which is essential for maintaining dimensional accuracy and consistent performance during lifting operations.
One end of each blank is flattened under high pressure, then drilled or punched with a rebar hole. This reinforced opening ensures secure rebar integration, improving load transfer efficiency during lifting.
The opposite end is precisely threaded using CNC tapping machines. This ensures smooth, accurate threading for secure attachment to lifting loops, hoist rings, or other lifting devices without risk of thread damage.
During production, dimensional checks, threading tests, and surface inspections are carried out to ensure every socket meets exact tolerances and performance requirements. Non-conforming pieces are rejected immediately.
The sockets are treated with corrosion-resistant coatings, such as galvanizing or other finishes, to enhance durability and ensure they withstand harsh working environments while maintaining structural integrity.
A final inspection verifies coating thickness, uniformity, and adhesion, as well as dimensional and mechanical properties, before products are cleared for packaging and shipment.
Sockets are securely packed to prevent damage during transit. We offer flexible delivery schedules and global shipping options to meet your project timelines, with tracking and regular status updates provided.
