Rebar Spacer Wheels are a type of plastic support designed for precast concrete that is used to fix the position of the rebar and maintain the distance between it and the formwork. Its core function is to ensure uniform thickness of the concrete cover after pouring and avoid the risk of corrosion caused by exposed or insufficiently covered rebar15. This type of product is usually made of high-strength plastic (such as PA, HDPE), which has corrosion resistance, high temperature resistance and aging resistance, and is suitable for vertical walls, horizontal floors and complex structures.
