Many of the concrete structures constructed today are reinforced with rebar. Rebar is essentially a series of metal rods that are suspended within a concrete slab to help provide structural support over time.

In order for concrete structures to last, their rebar frame needs to be secure. You will need to use a range of rebar accessories alongside your rebar to guarantee the strength and stability of your frame.

1. Rebar Chairs

Rebar must be fully embedded into a concrete slab to provide the type of support needed to withstand the test of time. This means that once the rebar frame has been assembled, it needs to be suspended off the ground to allow concrete to settle beneath the frame as well as above it.

Rebar chairs are the accessories used to provide this suspension. The chairs are placed beneath major connecting points on the frame. A rebar chair can be made from stainless steel, plastic, or other non-corrosive materials.

It's important to choose the right chairs for your project, as you don't want the feet of the chair to puncture through any vapor barriers you have installed beneath your concrete slab.

2. Spacer Wheels

Concrete is used to create many different shapes within the construction industry. If you are attempting to pour a concrete column or beam, you will want to invest in spacer wheels to assist with your project.

Spacer wheels are designed to hold the rebar frame at the center of the cylindrical concrete structure while the concrete cures. Each spacer wheel features an internal webbing that holds the rebar in place.

Since spacer wheels are round, they won't tip over if the rebar they support is moved during the concrete pouring process.

Be sure that you pay close attention to the size of the rebar you are using before you buy spacer wheels so that you can invest in accessories that provide the perfect fit.

3. Tip Spacers

Anytime rebar is installed vertically, tip spacers should be used to provide adequate support. A tip spacer is designed to work well with a top or bottom concrete cover. These spacers have an elongated tip that supports the rebar and positions it at the desired height.

The best tip spacers can also help improve the flow of your concrete during pouring. Using quality tip spacers can prevent any concrete breakouts that might compromise the dimensions of your finished structure.
