Pulwell composite R-bar:
Pulwell manufactures composite
R-bars by combining the pultrusion process and an in-line winding & coating
process for the outside sand surface. The FRP composite rebar is made from high
strength glass fibers along with an extremely durable vinyl ester resin. The
glass fibers impart strength to the rod while the vinyl ester resin imparts
excellent corrosion resistance properties in harsh chemical and alkaline
environments. For improved stiffness and mechanical properties a carbon/vinyl
ester product is available. FRP rebar significantly improves the longevity of
civil engineering structures where corrosion is a major factor. As compared to
con-ventional steel rebars, composite rebars should be a suitable alternative
to steel reinforcing in:
¡¤ Architectural Concrete: cast stone, architectural cladding,
balusters, column facades, window lentils, architectural precast elements, hand
railing, and statuary and fountains, etc.
¡¤ Concrete exposed to de-icing salts
in: bridge decks, railroad
grade crossings, median barriers, parking garage elements, and salt storage
facilities, etc.
¡¤ 
Concrete exposed to marine salts in: seawalls, water
breaks, buildings & structures near waterfront, aquaculture operations, and
floating marine docks, etc.
¡¤ Applications
Subjected to Other Corrosive Agents: Wastewater treatment
plants; petrochemical plants; pulp/paper mills; liquid gas plants; pipelines /
tanks for fossil fuel; cooling towers; chimneys; mining operations of various
types; nuclear power and dump plants.
¡¤ Applications
Requiring Low Electric Conductivity or Electromagnetic Neutrality: Aluminum and copper
smelting plants; manholes for electrical and telephone communication equipment;
bases for transmission / telecommunication towers; airport control towers;
magnetic resonance imaging in hospitals; railroad crossing sites, and
specialized military structures.
¡¤ 
¡¤ Tunneling /
Boring Applications Requiring Reinforcement of Temporary Concrete Structures: Structures including mining
walls; underground rapid transit structures and underground vertical
shafts.
¡¤ Weight Sensitive
Structures: Concrete construction in areas of poor load
bearing soil conditions, remote geographical locations, sensitive environmental
areas, or active seismic sites posing special issues that the use of
lightweight reinforcement will solve.
¡¤ Thermally Sensitive
Applications: Apartment
patio decks; thermally insulated concrete housing and basements; thermally
heated floors and conditioning rooms.
Reasons Why Composite R-bar is Superior to Epoxy Coated Steel Bar:
¡ï Non-corrosive
¡ï Tensile strength is more
than twice that of steel
¡ï Non-metallic and
non-conductive
¡ï Consistent modulus of
elasticity
¡ï Deformation patterns are
the same as with steel
¡ï Four times lighter than
steel
¡ï Pre-fabricated ACI
standard angles and bends available
¡ï Coefficient of thermal
expansion more similar to concrete than that of steel
