[header] How to bend rebar [title] Understand the structural issues possible with manually-bent rebar and know how to avoid them. [step] When you bend metal, you naturally weaken it. When done correctly, however, you can minimize damage and still get the shape you need to complete the project. <sep> (A) [substeps] Badly bent rebar acts as a buffer for the metal particles of the laser beam. The piece of rebar you are bending dissolves when squeezed into contact. (B) This effect is part of the re-bend method. The process is a little different than rebending a rubber band, but the difference is that you bend it in half by simply opening up a v on each end. (C) Because of this, it's important for you to know how to modify the shape you want the rebar to be. If you have a badly bent rebar, you'll likely create grooves in the rebar that introduce excess material. (D) Keep the following in mind as you work : [substeps] Always note the grade and size of the bar you're bending, checking against the equipment you're using to ensure it works. Check with your project engineer to ensure your bends meet the minimal internal bend diameter.
