Long Wavy Lifting Insert is an accessory embedded in concrete precast blocks for lifting concrete precast blocks. Its wavy tail can transfer the load more evenly to the concrete block. It needs to be used with Lifting Loops. Its usage needs to be determined according to the weight of the concrete block, the lifting method, the angle and other information.
Its head is made of stainless steel, 20#, Q345D steel pipe, and the tail is made of three kinds of threaded steel: HRD 400, 500, 600. One end of the tail is straight and the other end is curved into a wave shape. The two parts are connected by extrusion.
Conventional quality inspection items include thread specifications, thread depth, overall length, aperture, and tensile performance. The tensile performance test requires a safety factor of more than 3 times. Each batch of orders needs to be strictly sampled and tested.
The surface treatment methods of the head of Long Wavy Lifting Insert are mainly electro galvanizing, hot-dip galvanizing, and original black (only dipped in anti-rust oil).
Common international certifications are CE certification and factory ISO 9001 certification.
1. Cut steel pipes and rebars according to size requirements, 2. Bend rebars, 3. Tap steel pipes, 4. Surface treatment of tapped steel pipes, 5. Extrude steel pipes at the straight ends of rebars, 6. Detect the threads, dimensions, tensile properties, etc. of Long Wavy Lifting Inserts, and 7. Packaging. Here, we will introduce its production process to give you a more intuitive understanding of why the Long Wavy Lifting Inserts we supply have higher quality.
Our quality control center has photometers, hardness testers, electron microscopes, impact testers, tensile testers, salt spray testers, CMMs, vernier calipers, micrometers, go and no-go gauges, etc. to complete more comprehensive testing.
Calibrated CMM and vernier calipers measure insert dimensions, thread diameter, and length to tolerance requirements.
Electronic tensile machine tests each batch to a 3× safety factor, confirming pull-out strength exceeds specified SWL up to 8 tons.
Automated counting systems and manual audits verify order quantities, ensuring no shortages or overages before packing and dispatch.
Final inspections include visual checks and random sampling of inserts, ensuring all CE and ISO 9001 criteria are fully met.
