Fiberglass Rebar Sizes

Fiberglass rebar, also known as FRP (Fiber-Reinforced Polymer) rebar, is used in concrete reinforcement due to its non-corrosive nature and its high strength-to-weight ratio. Here are common sizes and types you might encounter:

1. Diameters: Fiberglass rebar is available in various diameters, typically ranging from about 6 mm to 32 mm. These diameters correspond roughly to the conventional steel rebar sizes #2 through #10.
2. Lengths: Similar to steel rebar, FRP rebars can be custom cut to any length based on the requirements of a construction project. However, they are commonly sold in lengths of 12 meters, which is standard for easy handling and transport.
3. Shapes: Besides straight rods, fiberglass rebar can be bent or formed into various shapes depending on structural needs, such as hooks or spirals. This flexibility makes it suitable for a range of applications, from simple slabs to complex infrastructure projects.
4. Surface: Fiberglass rebar typically has a roughened surface to enhance bonding with concrete. This texturing can vary slightly depending on the manufacturer but generally aims to improve the mechanical grip within the concrete matrix.
5. Tensile Strength: The tensile strength of fiberglass rebar is usually higher than that of traditional steel rebar, but its specific strength can vary based on the composition of the fibers and the manufacturing process.

These characteristics make fiberglass rebar particularly useful in environments that are corrosive or where magnetic interference needs to be avoided, like in medical imaging facilities or coastal structures.
