Product Overview：

PC ribbed bar lifting sleeve is a standard embedded lifting fitting specially designed for precast concrete (PC) components. The exterior is formed with continuous transverse ribs, which can be tightly anchored inside concrete after pre-embedding during component fabrication. Internal precision female thread matches standard lifting bolts; construction crews can quickly install lifting screws for hoisting, transportation and installation of precast walls, beams, columns and staircases. Adopt overall processing + galvanized anti-corrosion treatment, high pull-out resistance and mechanical strength, effectively avoid falling risks during lifting operation.
PC lifting sleeves are applicable to precast concrete wall panels, precast columns, precast beams, precast stairs, precast balcony slabs and other prefabricated components in residential buildings, commercial complexes, municipal precast projects and infrastructure construction worldwide.

Core Advantages：

1.Ribbed Outer Surface for Firm Anchoring 
Full spiral ribs on the outer wall greatly enhance bonding force with concrete, strong pullout resistance, no shedding under rated lifting load.

2.Precision Internal Thread 
Standard internal thread with smooth tooth surface, good fit with lifting studs, convenient and fast bolt assembly on site.

3.Hot-dipped Galvanized Anti-rust Treatment 
Color galvanized layer isolates air and moisture, prevents rust during component storage and long-term service, adapts to outdoor and humid construction environments.

4.Integral Forming & High Mechanical Strength 
One-piece steel processing without welding joints, stable mechanical property, meets the safety load requirements of precast component hoisting.

5.Complete Sizes & Customization Support 
Conventional sizes match M12/M14/M16/M18/M20/M24 with various customized lengths. Special dimensions can be produced according to client drawings.

6.Simple On-site Operation
 Directly embedded in concrete when pouring precast parts; only matching lifting bolts are needed for hoisting work, improving construction efficiency of prefabricated buildings.
