PVC Tie Sleeve

PVC Tie Sleeves are an essential accessory for aluminum formwork systems. They maintain accurate wall thickness, protect flat ties, and enable easy removal after concrete casting.

Designed for precision, durability, and repeated reuse, PVC tie sleeves supplied by Youto play a critical role in achieving high-quality concrete finishes and efficient formwork cycles in modern construction projects.

These sleeves act as a protective conduit for flat ties, preventing direct contact between flat ties and concrete. This not only ensures smooth extraction of flat ties after de-shuttering, but also eliminates concrete damage and maintains structural uniformity.

High-Quality Material & Manufacturing Standards

Youto Tie Sleeves are manufactured from high-grade PVC material, which is renowned for its superior strength, flexibility, and resistance to harsh construction site conditions. The sleeves are precision-extruded to maintain consistent internal and external diameters, ensuring perfect compatibility with standard flat ties.

Key material benefits include:

High resistance to cement slurry and moisture

Non-reactive with concrete

Smooth inner surface for easy tie removal

Excellent dimensional stability

Long service life with repeated use 

These properties make the sleeves suitable for intensive use in high-rise and mass housing projects.

Application in Aluminium Formwork 

Flat tie sleeves are inserted between aluminium formwork panels before placing the wall tie rod. Their primary function is to maintain consistent wall thickness and ensure clean, uniform concrete surfaces. 

Common applications include:

Shear wall construction

Core wall and lift shaft formwork

Retaining walls

Structural walls in high-rise buildings

Repetitive slab-to-slab construction cycles 

After concrete curing, wall ties can be removed easily, leaving a clean cavity that can be filled or finished in accordance with project requirements. This process enhances the aesthetic effect of the structure and reduces the amount of subsequent repair work.
