Standard Plastic Circles for Concrete Reinforcement are specially designed to provide a consistent 50mm cover for reinforcement bars ranging from 8mm to 16mm in diameter.

Manufactured from durable copolymer polypropylene, these spacers ensure precise rebar positioning within concrete structures, enhancing both durability and compliance with building standards.

Ideal for vertical and horizontal reinforcement applications in slabs and foundations, they are suitable for high-load conditions and offer excellent stability in both precast and in-situ concrete projects.

Their UV-resistant composition makes them highly suitable for outdoor or exposed environments.

These heavy-duty spacers are robust, easy to install, and help maintain bar alignment during concrete pours, ensuring structural integrity in foundations, walls, and floors.

Designed to securely hold rebar in place while preserving consistent spacing, they promote free concrete flow and help prevent weak points caused by uneven cover.

Particularly effective in column and wall casting, they support precise vertical alignment where accuracy is critical.

Together, this range of Standard Plastic Circles offers a comprehensive solution for achieving accurate and reliable rebar cover across a variety of concrete construction scenarios.
