If you need to elevate rebar above ground before pouring concrete, one of the best supportive products you can use is a chair. It will keep the rebar in the perfect position as concrete pours over it. Here are some tips that can help you purchase an optimal rebar chair variety.
Get a Snap Design For Extra Support
If you want to verify that your rebar materials are going to stay on chairs that elevate their height, then look for a chair variety that has a snap-on design. You'll push rebar materials hard enough to snap them in place on top of the chairs, thus keeping movement to a minimum.
Even if you bump against the rebar when pouring concrete over it, the chairs are going to keep the rebar locked in place. The only way rebar will be able to come off is if you physically pick it up and unsnap it from the clasping mechanisms on top of these chairs.
Make Sure the Base is Stable
When you set up chairs to support rebar around a particular construction site, you want to trust that these accessories won't move around at all. You can feel great about this quality by looking for rebar chairs that have a stable base.
They should be set up completely flat and not fall victim to movement even when bumped. You can test out this base design by ordering a couple of different chair models and then seeing which one provides the best support for rebar.
Look for Adequate Structural Integrity
Some of your rebar materials may be really thick and weigh a lot. In that case, you need to make sure your rebar chairs have enough structural integrity to hold this weight without collapsing or tilting over. Then you can ensure that the rebar is going to stay in place as you apply concrete over it for reinforcement purposes.
You can make sure structural integrity isn't a factor you have to worry about if you get rebar chairs made from durable materials like steel. This material is going to take the full weight of the rebar and not fall victim to structural damage.
You can elevate the height of the rebar in a controlled manner when you invest in rebar chairs. There are several types you can get today, but if you focus on a couple of key attributes, these accessories will make rebar much easier to work with around a construction site.
