What Customers Are Saying
Customers overwhelmingly praise fiberglass rebar as a durable, lightweight, and rust-resistant alternative to steel, particularly for outdoor, coastal, and high-moisture applications. Most highlight its ease of handling, simple cutting with standard tools, and seamless installation using familiar methods. Many emphasize its superior corrosion resistance prevents long-term structural failure. However, reviewers consistently warn that protective gear is essential, as fiberglass can cause skin irritation and invisible splinters during handling. A few note it cannot be bent and find it less flexible than steel, though most consider these trade-offs worthwhile for durability.
Customer review summary generated by AI, including incentivized reviews.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.
Good Alternative to traditional rebar
This seems like a good alternative to steel rebar, especially for home projects. It is lighter and I do like that it is corrosion resistant. It is lighter that steel rebar and bends easily when necessary.
Must wear Gloves
The fiberglass will dig into your hands. you must wear gloves to work with fiberglass rebar
Great for Halloween
Bought these to anchor some halloween decorations. Did want to handle the rusty rebar
Better looking than an ugly metal one - am using it to hold up a new tree I planted. Looks nice!

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