Guidelines for handling and Installing GFRP Rebars


Cutting

Can be cut on-site using a simple diamond blade, grinder, or masonry saw


Handling

Avoid dragging rebars on rough surfaces to prevent damage to the resin coating


Bending

Does not require bending in the field — factory-bent shapes available if needed


Storage

Store rebars on a flat, non-abrasive surface, and support them at regular intervals


Tying

Tied using standard plastic zip ties or nylon-coated wire (metal ties are not recommended to avoid galvanic corrosion).


Mechanical Handling

Do not subject GFRP bars to sharp impacts or aggressive mechanical bending


Concrete Placement Compatibility

Compatible with most concrete placement methods.


Durability

FTC GFRP Rebars are highly durable in outdoor environments. While prolonged exposure to sunlight may cause discoloration, fading, or surface chalking due to oxidation or UV exposure, these effects are purely cosmetic and do not impact the structural performance


Spacers/Chairs

Place spacers/chairs at intervals that ensure proper concrete cover is maintained


Sunlight Exposure

For extended storage or exposure under direct sunlight, it is recommended to use a protective cover to minimize visual changes and maintain appearance
