Precast Concrete (PC) Construction
Ultra-lightweight and strong enough to withstand extreme environments, Completing the innovation of precast (PC).
PC construction involves fabricating components (PC members) at a factory, ensuring the required strength through rebar placement, formwork installation, concrete pouring, and curing. These components are then assembled on-site.

Precast Concrete (PC)
Road Bridge
Concrete Deck Panel
• Bridge decks are directly exposed to de-icing chemicals (chloride) in winter, making them prone to rebar corrosion.
• Using GFRP rebar instead of rebar in the construction of PC decks fundamentally resolves salt-induced corrosion, significantly improving the durability and lifespan of the structure.

Precast Concrete (PC)
Concrete Barrier
(PC Barrier)
• Road bridge barriers are also vulnerable to chloride damage, and are manufactured in PC form using GFRP rebar.
Precast Concrete (PC)
Underground Box Structures and Waterway Pipes
(PC Culverts)
• Applying GFRP to PC culvert components buried underground or above ground, such as manholes, sumps, and drainage ditches, enhances chemical resistance and creates a corrosion-resistant structure.
Precast Concrete (PC)
Marine Precast Structures
• Using GFRP rebar in PC components such as coastal retaining walls, breakwaters, and docks exposed to salt mist (sea fog) can prevent salt corrosion caused by seawater infiltration, extending the lifespan of the structure.
Precast Concrete (PC)
Railway Precast Sleepers
• Applying GFRP rebar to precast concrete slab tracks enhances insulation performance and resolves the problem of steel corrosion caused by cracks in conventional reinforced concrete track.
