What is the purpose of rebar in concrete?
Rebar provides essential strengthening to concrete by helping bind the concrete pour.
The reinforcing bar adds tensile strength to the natural compression benefits of concrete and helps it resist breaking and cracking.
This doesn’t mean concrete is weak. It simply needs a little assistance to improve its resilience.
Concrete is very strong under compression. It can take a lot of stress.
But without reinforcement, it would not provide enduring toughness in jobs like a driveway, parking area, yard, wall or patio.
Reinforcement ensures that compression and tensile strength work together. It is a perfect combination first discovered centuries back and constantly improved.
Cheat-Sheet: What Is Steel Reinforcing, And What Does It Do?
What are deformed reinforcing steel bars?
The steel rebar supplied by Quality Steel Supplies is produced in a corrugated pattern. Even though it is called deformed, there is nothing inadequate about it.
Deformation simply means it is designed with ridges to combine effectively with the concrete pour.
Some concrete reinforcement is smoother but plays the same strengthening role.
For pours such as driveways and yards, the most effective option is usually steel mesh.
Quality Steel Supplies offers this in a variety of sizes to match the layout and type of your job.

Where is steel reinforcement used?
A dividing or retaining wall is more likely to be suited to rebar. This applies to domestic driveways, parking areas and patios as much as commercial situations.
Reinforcement is also vital for sloping surfaces. Slopes or other surface variations add a challenge to concrete which reinforcing steel largely overcomes.
The reinforcing will not only strengthen the concrete pour but also improve its structural integrity. Without reinforcing, your concrete could potentially crack, break or sustain other damage from heavy usage and temperature changes.
Concrete and steel reinforcing are a natural match. They react very much in tandem to variations in temperature, especially during summer and winter extremes.
There are many types of rebar with hot-rolled steel the most widely used. Other possibilities include glass and carbon fibre or epoxy-coated steel. The coating helps resist corrosion.
The rebar and steel mesh available from Quality Steel Supplies is selected to specifically meet New Zealand conditions.

Buildings of reinforced concrete will normally be under the direction of experienced specifiers and other professionals.
They collaborate with us to choose the size of rebar required and its placement prior to a concrete pour.
We also work daily with many home handymen and building apprentices. We can help your decision-making from the early planning stage to completion.

What’s the difference between rebar and mesh?
Mesh is lighter and thinner than rebar. It is quick and easy to position in jobs such as laying driveways.
Mesh is usually the choice for home driveways while rebar is more appropriate if the likely load is very heavy and sustained.
Quality Steel Supplies staff are happy to discuss what is best for you.
Drop us an email or call Troy on 022 673 9877 or Jackson on 021 977 444.
The concrete depth also plays a role in what is best for reinforcing. If concrete is thin because of being unable to dig deeper it will need stronger reinforcement.
This varies from job to job so ask us or our sister company Quality Concrete Services for no-obligation advice.
Does rebar corrode?
In the long term, yes, rebar can possibly corrode.
But the correct laying of concrete with rebar or mesh ensures the concrete cover achieves a pH value high enough to avoid or minimise corrosion.
All rebar and mesh from Quality Steel Supplies meet the relevant Australia/New Zealand Standard.
This level of quality product also guards against corrosion.
Can rebar or mesh be seen in the concrete?
No, the reinforcing is completely covered by and bound into the concrete. Rebar is usually only visible in an unfinished job.
Quality Steel Supplies in Auckland provides protective caps for sharp ends that protrude during work-in-progress. They come in a universal size in a pack of 100.
Is there more than one size of rebar?
Yes, Quality Steel Supplies offers rebar varying from 10-32mm in diameter.
Our range includes both Grade 300E and Grade 500E options. The number in this coding indicates yield strength. The E is a ductility indicator and refers to earthquake resistance.
All bars carry clear markings which can be easily recognised.
