Purchase the rebar.

For complicated applications such as grade beams, foundation walls, tanks, and other projects, you will need to have specific shapes formed by a rebar fabrication specialist.

Here are some examples: • Stirrups - These are shaped rebar that hold the lateral reinforcement in a certain configuration, often called a cage. They create a framework that keeps these larger bars in position, and may be round, square, rectangular, or even complex combinations of shapes.
• Dowels - These are usually L shapes, or straight lengths of rebar with a ninety degree bend on one end. • Corner bars - These are also L shapes, with each side of the ell the same length. • Offset bends - These range from a simple Z shape to complex angles, used in reinforcing concrete walkway steps and steps (changes in elevation) in concrete footings. • Hairpins - These are U shaped rebar that are often used to interlock two or more individual mats of rebar to give lateral strength to the concrete casting.
• Candy canes - As the name implies, these are straight lengths of rebar with a U shaped bend on one or both ends, again to interlock two or more parallel reinforcing mats. Decide whether the concrete forms will be installed prior to placing your rebar.
For large footings where heavy rebar is to be used, the formwork usually is done first, for concrete walls and grade beams, one side of the form may be built prior to tying the rebar, but the rebar will need to be tied in place before the formwork is completed so bars can be positioned and tied in place. For concrete slabs, the subgrade (ground underneath the slab) is often pre-treated for termites, and a moisture barrier or dampproofing is installed before the mat is tied. Shake out the rebar.
