REBAR

FIBERGLAS™ REBAR Straight Bar

A PROVEN, SUCCESSFUL REINFORCEMENT SOLUTION FOR CONCRETE

Lighter. Stronger. Smarter Reinforcement.

Concrete cracks, water seeps in and corrosion of internal reinforcing steel causes concrete structure failure. Owens Corning® Fiberglas™ Rebar is a proven, successful alternative reinforcement that provides longer service life in a wide variety of applications.

Performance Attributes

EXTENDED SERVICE LIFE OF STRUCTURES
INCREASED PRODUCTIVITY
EXCEPTIONAL STRENGTH
  • Extended Service Life Of Structures

    • Fiberglas™ Rebar is a proven corrosion resistant reinforcement designed to provide structures with longer service life compared with structures reinforced with steel.

  • Increased Productivity

    • Four times lighter than steel, Owens Corning® Fiberglas™ Rebar can be installed faster with less labor.*

  • Exceptional Strength

    • Ultimate tensile strength of Fiberglas™ Rebar is twice the yield strength of steel.* <br> <br> * Based on sample testing of #5 rebar, GFRP exhibits linear-elastic behavior up to ultimate tensile strength.

APPLICATIONS

Transportation Structures - Bridge decks, traffic barriers, civil roadways, "soft-eye" for tunnels. <br> <br> Marine - Seawalls, piles <br> <br> Buildings - Balconies, wall panels, foundations <br> <br> High Voltage & Electromagnetic Fields - Light & heavy rail, MRI rooms

Field forming of Large Radius Curves: It is possible to field form the bar into large radius curves. This induces a bending stress in the bar which must be lower/smaller than the creep rupture limit/allowable stresses.

Packaging, Shipping and Labeling

Straight bars will be shipped to the project site in bundles. Bundle sizes vary by bar length and diameter. Bundle weights usually range from 1,500 lbs. to 3,000 lbs. Lead time is subject to plant production schedules at the time of order processing. Customer-specific packaging requirements may be available upon request. Material traceability markings per ASTM D7957 or CSA S807 will be present on straight bars.


Storage and Handling

Product should be covered or stored away from direct sunlight. Follow guidelines in ACI440.5-08, “Specification for Construction with FRP Bars.” In general, field handling and placement is the same as epoxy coated or galvanized steel bars. However, do not shear fiberglass bars. Field cut fiberglass bars using a fine blade saw, grinder, and carborundum or diamond blade. Sealing the ends of fiberglass bars is not necessary. Place support chairs at two-thirds the spacing of support chairs for steel rebar. Plastic-coated tie wires are the preferred option for most projects. Use plastic or nylon zip ties when required for electromagnetically neutral reinforcing. In precast applications, secure fiberglass bars to the formwork to avoid float during compaction.


Safety

When using and handling Owens Corning® Fiberglas™ Rebar, proper personal protective equipment (PPE) is required. Owens Corning® Fiberglas™ Rebar Straight Bar has a machined helical surface that may be abrasive to skin without proper PPE. Proper PPE includes canvas gloves and shirts with sleeves, long work pants, and sturdy work shoes or boots.

Regional Availability

Owens Corning® Fiberglas™ Rebar straight bars are available in North America and Europe.
