Rebar Support Chairs

150mm Support Chairs

200mm Support Chairs


Rust Prevention

Our products are designed to prevent concrete cancer in concrete sleeper applications by specifically positioning rebar away from direct contact to air and moisture.

Multiple Sizes

We have products to suit 150mm & 200mm Width Concrete Sleeper Moulds of any length.  Products support both n10 & n12 reinforcing bar

Dual Purpose

Our Rebar Support chairs are spun upside-down to offer rebar support where spans are greater than 2 meters. This ensures positioning remains intact


Minimal Footprint

Minimal footprint to the face of  the concrete sleeper ensures the surface appearance remains as intended.


Rebar Support chairs ensure that reinforced bars achieve the correct concrete coverage

Frequently Asked Questions

How do Rebar Support Chairs Prevent Concrete Cancer
Concrete cancer occurs within concrete when the internal steel reinforcing rusts from being exposed to air moisture.

When Rebar rusts – it expands, causing the concrete around the Rebar to be displaced, significantly compromising the strength and appearance of the concrete product.

Once concrete cancer starts the problem compounds as more of the steel is exposed to the elements (Moisture & Air) causing cosmetic and structural concerns.

Rebar Support chairs eliminate this problem by positioning Rebar inside concrete sleepers to a perfect position where the Rebar cannot be exposed to air moisture.
