Application / Bridges and Highways
Bridges and Highways
Bridges
Decks, Barriers, Parapets, & Abutments
Applications

Bridge decks, approach slabs, parapet walls, and barrier rails
Pile caps, piers, abutments, and retaining walls
Expansion joints and edge girders in high-chloride zones (e.g., near coasts or salted roads)
Why GFRP Rebar?

100% corrosion-free — ideal for areas exposed to de-icing salts and moisture
Lightweight → reduces crane load and simplifies deck placement
Extends bridge service life from ~25 years (steel) to 80 - 100 years
Why GFRP Mesh?

Used as secondary reinforcement for crack control on decks, overlays, and parapet faces
Prevents shrinkage cracking from temperature fluctuations
Non-magnetic → allows for magnetic particle inspection and structural health monitoring
Highways, Pavements & Barriers
Highways, Pavements & Barriers
Applications

Roadway pavement overlays and median barriers
Noise barriers, guard walls, and retaining panels
Jersey barriers and sound walls near coastal zones
GFRP Rebar

Prevents rebar corrosion from road salts, especially in freeze–thaw regions
Maintains load-bearing capacity over decades without delamination
4× lighter than steel → faster rebar cage assembly and lower handling costs
GFRP Mesh

Ideal for pavement joints, slabs, and surface reinforcement
Provides distributed reinforcement in thin pavement sections
Reduces reflective cracking and fatigue in concrete roadways
Tunnels, Culverts & Underpasses
Tunnels, Culverts & Underpasses
Applications

Lining segments, portals, and retaining walls
Drainage culverts, access tunnels, and ventilation shafts
Advantages

GFRP bars eliminate the need for cathodic protection systems
High tensile strength ensures crack control in curved and confined sections
GFRP mesh provides uniform reinforcement across tunnel walls and arch surfaces
Precast & Modular Infrastructure
Precast & Modular Infrastructure
Applications

Precast barriers, slabs, and box culverts
Modular bridge components and deck panels
Advantages

GFRP rebar can be cut and shaped onsite without sparks or rust risk
Lighter precast units → reduced shipping weight and easier installation
Mesh used to reinforce thin precast panels and ensure surface durability
