Description
Plastic Chair Spacer Rebar – Durable Rebar Support for Concrete (Available in Mauritius)
Plastic Chair Spacer Rebars are durable support components designed to hold reinforcing steel bars (rebar) at the correct height within concrete structures. They ensure accurate concrete cover, which is essential for maximizing structural strength, preventing corrosion and improving the long-term durability of reinforced concrete. Suitable for slab work, beams, foundations and precast applications, these spacers provide stable support for rebar mats or cages during the pouring and curing of concrete. Now available in Mauritius, these spacers are especially useful for local concrete construction projects offering a reliable, cost‑effective solution to maintain structural standards in humid or coastal conditions.
