Sometimes you want to save money on various portions of a building project.
Imagine designing beautiful archways on your own property that are merely put in place 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 like lighting money on fire for no functional reason whatsoever. A building contractor is going to do the same thing, so you can’t just assume that some materials are chosen over others because the designer or builder are “cheap.” While this is also certainly possible, and you see it a lot across both residential and commercial properties, you still can’t assume that it’s always the case. That’s in part why it’s perfectly fine, and even recommended, 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 fine to build with traditional black bar rebar tie wire. But if you really needed that extra corrosion resistance, that’s when products like galvanized and stainless steel rebar tie wire are extremely effective. Both can be found at most rebar suppliers, often in 14 gauge and 18 gauge measurements. Often airplane runways are made with reinforced concrete, which itself is made with a variety of different kinds of rebar depending on the load, the size of the airport, and the location.
