Product Overview
Straight fiberglass rebar (also known as GFRP rebar, FRP rebar, fiberglass reinforcing bar, or composite rebar) is a pultruded, non-corrosive concrete reinforcement bar designed as a lightweight, durable alternative to steel rebar in applications where moisture, salt, chemicals, or electromagnetic interference would cause rust. It provides long-service-life reinforcement without the risk of corrosion, making it ideal for bridge decks, seawalls, parking garages, chemical plants, MRI facilities, and other demanding concrete structures requiring easy handling and reliable performance.
Key Features
- Corrosion resistant in wet, salty, and chemical environments
- Lightweight for easier transport and installation
- Non-conductive and non-magnetic
- High tensile strength
- No rust staining on concrete surfaces
- Low maintenance over the service life of the structure
- Available in custom lengths and diameters
Applications
Straight fiberglass rebar is used in a wide range of civil and industrial construction projects.
Typical application scenarios:
- concrete slabs on grade
- bridge and deck reinforcement
- seawalls and coastal structures
- parking garages
- chemical plant floors
- wastewater treatment structures
- road barriers and retaining systems
- precast concrete components
- insulated or electrically sensitive structures
This product is especially suitable where long-term durability is more important than field bending.
Material and Manufacturing
Straight fiberglass rebar is manufactured from continuous glass fibers and specialized resin systems using a pultrusion process.
Common material composition
- Reinforcement: glass fiber
- Matrix: polyester resin or vinyl ester resin, depending on project requirements
- Surface: sand-coated, ribbed, or customized surface for bonding performance
Manufacturing notes
- produced in straight form
- cut to required length
- made to match project drawings or standard sizes
- stable profile with consistent cross-section
Note: Resin type, fiber content, surface texture, and diameter should be selected according to the application, load demand, and exposure conditions.
Advantages of Straight Fiberglass Rebar
1. Corrosion Resistance
It does not rust, so it is suitable for marine, coastal, de-icing salt, wastewater, and chemical environments.
2. Lightweight Installation
Compared with steel, straight fiberglass rebar is much lighter, which helps reduce handling effort and installation time.
3. Long Service Life
It helps reduce repair frequency in structures exposed to corrosive conditions.
4. Non-Magnetic and Non-Conductive
It is suitable for MRI facilities, power-related structures, and other applications where metal reinforcement may cause interference.
5. Reduced Lifecycle Cost
Although the initial material selection may differ from steel, the long-term maintenance burden can be lower in corrosive environments.
