What Customers Are Saying
The fiberglass rebar is described as lightweight, easy to cut and work with, and a durable alternative to traditional steel rebar, especially in applications requiring rust resistance. However, there are significant safety concerns, as the material can cause painful splinters and glass shards that are difficult to see and remove, posing a serious hazard. Customers emphasize the importance of wearing thick gloves when handling the rebar, and some would not recommend the product due to the safety risks. The rebar is also more flexible than steel, limiting its usefulness for certain applications.

This stuff is JUNK
This stuff is garbage. More expensive than regular rebar, you can’t bend it, and it leaves all kind of splinters in your hands since it’s just a piece of fiberglass. DO NOT BUY!
