In precast concrete construction, accurate positioning of rebar is a core element to ensure the strength and durability of building structures. As an innovative accessory in modern engineering, Rebar Spacer Wheels are becoming the "invisible guardian" of the global construction industry with their efficiency and reliability. Plastic Rebar Chair is made out of durable non-corroding high-density plastic which is both strong and light. Our rebar chair systems cannot change shape and will provide a uniform concrete cover. A plastic Rebar Chair for concrete support can be used in tilt-up and slab work. They are stable and economical. Its fastening system is strong and versatile.

Why has Rebar Spacer Wheels For Precast Concrete become the industry standard?

Precisely control the thickness of the concrete cover

Traditional construction relies on sand pads or temporary brackets, which can easily lead to uneven thickness of the cover, while the spacer wheel achieves precise positioning through standardized sizes (such as 1 inch, 3 inches, etc.) to ensure compliance with engineering specifications.

Open design optimizes concrete fluidity

The hollow structure of the spacer wheel allows concrete to flow freely, avoiding the formation of voids or honeycomb defects due to support obstruction, thereby improving the overall density of the structure. Some products also adopt a "point contact" design, which only contacts the formwork through plastic protrusions, reducing the need for repairs after demolding.

Installation efficiency increased by more than 50%

The snap-in design does not require tying wires, and only needs to press the steel bar into the center slot to complete the fixation. It is especially suitable for #3-#6 steel bars, which greatly shortens the construction period.

Long-term durability and environmental protection

High-density plastic materials are resistant to acid and alkali corrosion, and their service life far exceeds that of traditional metal supports. Plastic materials are recyclable and in line with the trend of green buildings.

Key parameters for selection:

Rebar specifications: Suitable for #3-#6 rebar (diameter 9.5mm-19mm).

Protective layer thickness: Select 1 inch to 3.5 inches according to design requirements.

Packing specifications: For large projects, large packaging of 200-2500 pieces per box can be selected to reduce costs.
