What Customers Are Saying
Customers overwhelmingly praise fiberglass rebar as a lightweight, corrosion-resistant alternative to steel, with most highlighting reduced physical strain, ease of cutting with standard tools, and elimination of rust-related concrete damage—especially valued in coastal or humid environments. Installation remains intuitive using familiar methods like zip ties and rebar chairs. A consistent theme emphasizes the necessity of wearing gloves during handling, as fiberglass fibers can cause skin irritation and splinters. A few note it cannot be bent like steel and costs more, but most consider these minor trade-offs for superior durability and ease of use.

Perfect
It works great
Great rods
These were purchased to be used as bank poles by my grandson. He rigged these ups for catfish lines. He entered a tournament and used these and won!!
Fiberglass Re-Bar, nice
Michael B. did a nice job helping me load the truck. Re-Bar is easier to cut, just can't bend it like steel. My layout didn't need bends so this was perfect. While the material is coated, there is still fiberglass dust while cutting and can split on the end if not careful. Overall, great alternative and I would use it again.

Why doesn't Lowes sell the corresponding pre-bent corners?

Are there corner pieces available since this material will not bend to form a 90 degree angle?
