Hot Selling Construction Accessories Concrete Rebar Wheel Spacer for Formwork Accessories
Our heavy-duty plastic wall spacers (also known as plum-shaped rebar chairs or concrete cover blocks) are specially designed construction accessories for vertical reinforcement positioning in concrete walls, columns, and foundations. The unique thickened plum-blossom design provides exceptional stability and load distribution, ensuring precise concrete cover thickness while preventing reinforcement displacement during concrete pouring. Ideal for all types of concrete wall construction including retaining walls, basement walls, shear walls, and precast wall panels.
Key Features
Thickened Heavy-Duty Design: Extra material thickness provides superior strength and load-bearing capacity, making these spacers ideal for heavy reinforcement cages and tall wall constructions.
Unique Shape: The shape design offers 360-degree stability, preventing tilting or movement during concrete placement and vibration.
Precise Cover Control: Manufactured to exact dimensional tolerances, ensuring consistent concrete cover thickness as per engineering specifications.
High Compressive Strength: Engineered plastic material withstands the weight of vertical reinforcement and construction loads without deformation or collapse.
Large Contact Surface: The structure provides wider contact with formwork, distributing pressure evenly and preventing formwork damage.
Easy Fixing: Designed for quick and secure attachment to vertical and horizontal rebars with simple or tie-wire fixing options.
Corrosion Proof: 100% non-metallic construction eliminates rust stains on finished concrete surfaces.
