GLASSPREE® TS fiberglass rebar represents an advanced, high-performance solution for the structural strengthening of reinforced concrete works, suitable both for new construction and for the upgrading or rehabilitation of existing structures.
Manufactured from glass fiber composite reinforced with vinyl ester resin, these GFRP rebars combine high mechanical performance with lightweight properties, corrosion resistance, and long-term durability, ensuring safe and reliable glass fibre reinforced concrete structures. Thanks to their quartz sand coating, GLASSPREE® TS fiberglass reinforcement bars ensure excellent bonding with concrete, providing effective stress transfer and enhancing the reliability and lifespan of the structural system.
Compared to traditional steel reinforcement, GLASSPREE® TS GFRP rebar provides numerous advantages:
 |
DurabilityService life exceeding 100 years – twice that of steel. |
 |
LightweightWeighs just one-quarter of steel, simplifying handling and transport. |
 |
High Tensile StrengthTensile capacity up to 1100 MPa. |
 |
Corrosion ResistanceIdeal for marine and chemically aggressive environments. |
 |
Thermal StabilityMaintains mechanical properties even under extreme temperatures. |
 |
Electromagnetic NeutralityNon-conductive. No electromagnetic interference. |
 |
Environmental SustainabilityReduced maintenance and compatible with green concrete technologies. |
 |
Cost EfficiencyLower transport, installation, and maintenance costs. |
GLASSPREE® TS fiberglass rebar is designed for the reinforcement of reinforced concrete infrastructures, including transport structures (bridges, viaducts, tramways, metro platforms), marine and hydraulic works (piers, quays, breakwaters, weirs, and canals), as well as civil and industrial constructions such as foundations and containment tanks and historic building restoration.
Thanks to their versatility, GFRP rebar can be used both as primary reinforcement in new concrete pours and as post-installed bars for localized repair and strengthening of reinforced concrete elements such as beams, columns, pillars, panels, and slabs.
Sireg Geotech was the first company to certify and market fiberglass rebar for reinforced concrete with CE marking in Europe, ensuring full compliance with European construction product standards. The AVCP 1+ conformity system subjects production to continuous, rigorous third-party testing, guaranteeing product consistency, traceability, and safety.
