If you are planning a building project that involves reinforced concrete, you will need to know about the uses of structural steel cut and bent rebar and rebar sizes in construction.
Cut and bent rebar: what is it?
Concrete has a low tensile strength, which means that it is prone to breaking under tension. In contrast, steel has a high tensile strength, meaning it is capable of bending without breaking. Its compressive strength, however, is not as great as that of concrete.
Cut and bent rebar is therefore used to combine the high compressive strength of concrete with the tensile strength of steel, making for a far stronger structure that would be possible with concrete or steel alone.
The addition of concrete reinforced with cut and bent rebar greatly increases the structural integrity of a build and its ability to withstand force – ideal for small and large construction projects alike.
Cut and bent rebar sizes: onsite or by manufacturers?
Structural steel rebar is often cut and bent to size manually by workers at the build site. This can be problematic for two reasons.
Firstly, it is an inefficient means of preparing the rebar, often resulting in wasted material. It is also a time-consuming process, undertaken by workers who are often not skilled or experienced in bar bending to the appropriate British Standards in steelwork. Both the wasted rebar and the wasted time are at the client’s expense, impacting the budget for the build.
We cut and bend structural steel to each client’s exact specifications at our own steelworks in Enfield, North London to guarantee the best results. We use our expert knowledge and specialist cutting and bending equipment to provide an assurance of quality in line with the BS 8666:2005.
Not only is this a quicker and more cost-effective means of meeting the requirements of a build, but it also produces exact rebar sizes and a better-finished result.
Cut and bent rebar sizes: what size and shape do I need?
Every build is different and each project requires a customised selection of cut and bent rebar to fulfill the requirements of the project.
Rebar comes in a wide range of sizes and diameters designed for builds from small housing projects through to major construction or industrial works. At Cannon Steels we stock 8mm to 40mm steel rebar to suit almost any project.
We will be able to advise you on the correct size of rebar to suit your needs and we will also be able to advise you on the most cost-effective way to accomplish your build.
It is also possible to buy cut and bent rebar in a range of different shapes to suit the needs of building projects where standard straight rebar is not used. When used correctly, cut and bent rebar can revolutionise a build.
Your architect or engineer’s drawings will often be accompanied by a bar bending schedule, which will identify the exact shape of rebar you require for your build.
Rebar cut and bent to a helix shape dramatically increases the security of reinforced concrete, which binds around it, preventing cracking at a molecular level and reducing the amount of structural steel needed to strengthen the building.
