#4 Hemp rebar is woven fiberglass bound together with a plant-based resin containing 30% hemp seed oil.

Steel rebar was invented in the early 1900’s and the technology has not improved much since. This bio-based FRP rebar is a great leap forward in efficiency, strength, durability, and material sourcing. This is achieved by using natural fibers and synthetic fibers with a plant based matrix specially designed for optimal properties.
