Plastic Spacers

Plastic spacers are essential in reinforced concrete construction. They keep steel reinforcement in the correct position before and during concrete pouring. As a result, they help ensure structural integrity and long-term durability. Joluka offers a wide selection of plastic spacers that combine strength, precision, and ease of use. To begin with, the Plastic Snake Spacer is ideal for horizontal reinforcement in slabs and beams. It comes in 0.5-meter sections that clip together, forming a continuous support line. This design eliminates the need for tying, which in turn saves time and reduces labour. Moreover, its open structure allows concrete to flow freely, preventing air pockets and ensuring a smooth finish. Sizes range from 20mm to 55mm, making it suitable for various cover requirements. In addition, the Combi Spacer supports double-layer reinforcement in slabs. It holds both the top and bottom layers of steel in place with minimal contact on the shutter. This makes it especially useful in both in-situ and precast concrete applications. It works best with steel diameters up to 6mm and is available in sizes such as 15mm and 20+30mm combinations. For vertical applications, the Circular Spacer offers 360° cover. It clips securely onto rebar and fits diameters from 4mm to 16mm. Furthermore, its open design promotes excellent concrete flow and reduces the risk of voids. Made from 100% recycled plastic, it is both strong and environmentally friendly. Sizes range from 12mm to 75mm, and it comes in grey or black. Meanwhile, the Chair Spacer is designed for horizontal reinforcement in suspended slabs and beams. It supports steel diameters from 6mm to 40mm. Its concave seat holds the rebar firmly, while the wide base on larger sizes (60mm to 100mm) adds extra stability. Additionally, it includes hooks for binding wire and recesses that allow concrete to flow without obstruction. Made from recycled high-density polypropylene, it can withstand loads up to 4 kN. Overall, Joluka’s plastic spacers are quick to install, durable, and environmentally responsible. They are suitable for a wide range of construction needs—from residential slabs to large-scale infrastructure. Whether you're working on-site or in a precast yard, these spacers help you build with confidence, accuracy, and efficiency.
