Rebar grid is one of the most commonly used concrete reinforcing steel products, from residential floor slabs to concrete runways and other structural construction elements.
Sometimes also called rebar mesh, or reinforcing fabric, it is supplied in various sizes to cater to different specifications.
Concrete has excellent compressive strength, which is enhanced by the inclusion of steel reinforcement. Rebar delivers tensile strength to concrete, allowing it to resist lateral forces as well as imposed loads.
Why Use Rebar Grid?
Rebar grid, set out across any size slab, helps to stabilise and strengthen concrete. Steel reinforcement grid is the simplest, and fastest way to install rebar. It is electrically welded in several size configurations to cope with a range of specifications.
Adding steel to concrete in a pre-made grid formation delivers a fantastic composite structure. The concrete receives tensile strength, while the steel is protected from corrosion.
It is possible to create a bespoke grid by tying individual rebar together, but this can prove time-consuming. Deploying pre-made, electrically welded grid delivers speed and accuracy, ensuring that the strength and resistance of rebar is even across the entire concrete area.
What do the Grid Numbers Mean?
The grid numbers tell you the amount of steel in relation to the square meterage of the rebar grid. A393 is made from 10mm steel rebar with 200mm square apertures. B503 is made from 8mm rebar, but has smaller apertures at 200mm by 100mm, which means more steel per square metre.
How Much Rebar Grid do I Need?
Working out how much rebar grid you need for a project is simple enough when it comes to raft foundations. Our raft foundation cost calculator, based upon a 10m square slab, can give you an indication of what you will need.
You will need to allow for rebar grid edge clearance, which could be up to 75mm for a slab edge that is exposed to weathering or is in direct contact with the ground. Recommended clearance reduces for slabs that are protected by other structural elements.
