   This concrete lifting inserts type is made from stainless steel seamless tube A2 or A4 standard. After being embedded installation into the concrete components,it has excellent corrosion resistance and rust resistance features. They are fixed in the concrete unit with reinforcement through cross hole, and the pre installed plastic inserted cap is embedded to prevent the concrete from penetrating into the thread from the bottom. 

   Because of the flexible reinforcement method, the socket can be widely used and applied. If the lifting chain of pipes, walls and floor slabs are at an angle of more than 15 ° with the vertical plane, the additional reinforcement must be used and placed on the other side of the socket, opposite to the tension. The reinforcement shall be in contact with the area around the socket and as close to the concrete surface as possible (dimension A shall be ≤ sleeve diameter).

The reinforcement shown here must be used when the unit is tilted, or when the lift is at the edge of the member, creating a shear pull on the inserts. This reinforcement shall be in contact with the inserts it encloses around the concrete surface and as close to the cover as possible (dimension A shall be less than or equal to the socket diameter). The series includes lifting inserts and cylindrical sleeves with cross holes, reinforcement, corrugated tails, sleeve plates, high load and crown foot anchors.

    After stripping, the concrete components can be transported by simple sling or hinged sling. Some types are available in the overloaded version. According to the different site, The concrete threaded inserts are available in RD, RB, Inch and metric internal thread versions. Lifting points are widely used in precast concrete construction, such as beams, walls, floors and so on. A steel bar is needed to transfer the load to the concrete through the cross hole.
