Periodically you want to save money on many portions of a building project.
Imagine designing beautiful archways on your own property that are merely put in arena for aesthetic properties only.
You’re not trying to build a bridge for humans or animals to walk on, so you need to buy materials that will result in a structure that can at least handle the elements. But trying to reinforce it for hundreds of pounds worth of weight is appreciate lighting money on fire for no functional reason whatsoever. A building corporation is going to do the same thing, so you can’t just believe that some materials are chosen over others because the designer or builder are “cheap.” While this is also undoubtedly possible, & you see it a lot across both residential & commercial properties, you still can’t believe that it’s regularly the case. That’s in part why it’s perfectly fine, & even suggested, to use traditional black steel rebar tie wire in situations where the rebar isn’t getting exposed to constant moisture. You wouldn’t want to waste precious stainless steel rebar tie wire on structures that are perfectly fantastic to build with traditional black bar rebar tie wire. But if you honestly needed that extra corrosion resistance, that’s when products appreciate galvanized & stainless steel rebar tie wire are severely effective. Both can be found at most rebar businesss, often in 14 gauge & 18 gauge measurements. Often aircraft runways are made with reinforced concrete, which itself is made with a variety of unusual kinds of rebar depending on the load, the size of the airport, & the location.
