Packaging, Shipping and Labeling
Bent bars will be palletized and shipped to the site. 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 tags per ASTM D7957 or CSA S807 will be attached to bent bar bundles.
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.
When using and handling Owens Corning® Fiberglas™ Rebar, proper personal protective equipment (PPE) is required. Owens Corning® Fiberglas™ Rebar Bent Bar has a sand coating 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.
Owens Corning® Fiberglas™ Rebar bent bars are available in North America and Europe.
