Marine & Coastal Infrastructure
Seawalls, Quay Walls & Bulkheads
Seawalls, Quay Walls & Bulkheads
Applications

Retaining walls, quay walls, and bulkheads exposed to tides or splashing
Mooring structures, dolphins, and dock foundations
Why F+G Rebar?

100 % corrosion-proof against seawater chlorides and sulfates
Eliminates spalling and rust expansion under tidal cycles
Lightweight for barge or over-water installation
Why F+G Mesh?

Provides secondary reinforcement in face panels and surface overlays
Controls shrinkage and temperature cracking caused by daily thermal shifts
Marine & Coastal Bridges
Marine & Coastal Bridges
Applications

Bridge decks, approach slabs, and parapet walls near saltwater zones
Piers, abutments, and pile caps subjected to splash or spray
Advantages

No corrosion from salt spray or de-icing salts
Extends bridge service life to 100 years + with zero cathodic protection
Compatible with AASHTO LRFD Bridge Design and FHWA corrosion-free specifications
Harbors, Piers & Docks
Harbors, Piers & Docks
Applications

Wharf decks, fenders, piling caps, and walkways
Port access ramps, loading bays, and jetty platforms
Benefits

Non-magnetic → safe for naval and shipyard environments
Resistant to chemical spills (fuel, oil, salt brine)
Reduces maintenance shutdowns for corrosion repairs
Offshore & Coastal Energy Facilitiess
Offshore & Coastal Energy Facilities
Applications

Offshore wind turbine foundations and cable vaults
Oil & gas platforms, seawater intake channels, and desalination plants
Why F+G Rebar & Mesh?

High tensile strength under cyclic and dynamic loads
Non-conductive — avoids galvanic corrosion with steel fittings
Superior fatigue resistance under vibration and wave loading
Desalination & Waterfront Utilities
Desalination & Waterfront Utilities
Applications

Intake/outfall tunnels, brine channels, chemical tanks
