Tubular lifting sockets are essential threaded inserts embedded in precast concrete to enable safe lifting, fixing, and connecting components. HULK Metal manufactures these sockets with high-grade materials, precision threads, and strict quality control. Our products meet CE and ISO 9001 standards, ensuring excellent load-bearing performance and corrosion resistance. Each socket is engineered for secure installation and long-term durability in various construction environments, making them reliable for bulk procurement projects.
A tubular lifting socket is a precision-engineered insert embedded in precast concrete elements to provide a secure threaded point for lifting, fixing, or connecting other components. Structurally, it is manufactured from a high-strength steel tube, with one end threaded to match lifting loops or lifting bolts. The opposite end features a transverse hole allowing reinforcing bars to pass through, improving anchorage within the concrete. A plastic stopper is often inserted between the threaded section and the transverse hole to prevent wet concrete from entering the thread area during casting. HULK Metal's tubular lifting sockets are CE and ISO 9001 certified, ensuring they meet stringent safety and quality requirements. With accurate dimensions, robust tensile capacity, and corrosion-resistant finishes, they deliver dependable performance in demanding construction environments, making them a preferred choice for contractors, builders, and precast concrete manufacturers seeking reliable lifting solutions.
Tubular lifting sockets work by creating a secure threaded anchor point within a precast concrete element. During casting, the socket is positioned with the transverse hole aligned for rebar insertion, ensuring strong internal anchorage. After curing, a compatible lifting loop or lifting bolt is threaded into the socket for hoisting or connecting. The design distributes the load evenly, minimizing stress on the concrete. This method ensures safer lifting operations and reduces the risk of structural damage during transportation and installation.
Tubular lifting sockets are widely used in precast concrete construction for lifting wall panels, beams, columns, staircases, and other structural elements. They provide a reliable threaded connection for both temporary lifting and permanent fixing of accessories or adjoining components. These sockets are suitable for use in residential, commercial, and infrastructure projects, especially where high safety standards are required. Their robust construction and secure anchorage make them ideal for repetitive lifting tasks in large-scale precast manufacturing operations.
HULK Metal's tubular lifting sockets offer higher strength, better corrosion resistance, and superior dimensional accuracy compared to conventional inserts. CE and ISO 9001 certifications guarantee compliance with strict international standards. The design ensures a safety factor above 3, reducing lifting risks. Shorter production cycles and strict quality inspections enhance efficiency and reliability. With customizable materials, threads, and finishes, they suit various project requirements. Their durability extends service life, lowering long-term replacement costs for bulk buyers.
Our team carefully reviews your drawings and specifications to determine the optimal material, thread size, and production process. We analyze load requirements and environmental conditions to ensure each tubular lifting socket fully meets your project's functional and safety needs.
We source high-quality stainless steel or carbon steel from trusted suppliers. Each batch undergoes chemical composition and mechanical property testing to confirm compliance with CE and ISO standards before entering production, ensuring strength, durability, and consistent performance in demanding applications.
High-strength steel tubes are precisely cut into blanks according to design specifications. This process uses advanced cutting equipment to ensure clean edges, accurate lengths, and minimal deformation, laying a solid foundation for consistent threading and drilling accuracy in later stages.
One end of each cut tube is machined with precision threads to match the required lifting bolt or loop. Our threading process ensures smooth engagement, accurate pitch, and uniform depth for secure and repeatable lifting operations in precast concrete applications.
A transverse hole is drilled at the opposite end to accommodate reinforcing bars. The hole is positioned precisely to ensure maximum anchorage strength within the concrete, improving lifting stability and reducing the risk of pull-out under heavy load conditions.
Every tubular lifting socket undergoes dimensional checks, thread gauge testing, and visual inspections. We confirm accurate measurements, defect-free surfaces, and proper hole alignment, ensuring each piece meets CE and ISO 9001 standards before moving to surface treatment or packaging.
Products are securely packaged to prevent damage during transport. We offer flexible delivery solutions and assist in freight planning to reduce transit times. Each shipment includes complete documentation, making customs clearance and inventory management more efficient for bulk buyers.
Our after-sales team provides technical guidance, product usage advice, and quality issue resolution. We support you throughout the installation process, helping ensure maximum lifting safety and efficiency. Feedback is collected to improve future production and customer satisfaction.
