FRP rebar

When sourcing FRP Rebar, you must prioritize the tensile strength, which should typically be 2 to 3 times higher than steel rebar. Ensure the modulus of elasticity meets your structural requirements, as FRP is more flexible than steel. Additionally, verify the fiber content (usually >70%) and the type of resin used (Vinyl Ester is preferred for high corrosion resistance over Polyester).

For North American markets, ensure the product complies with ACI 440.1R or ASTM D7957 specifications. For European projects, look for Eurocode 2 compliance. Always request ISO 9001 certification from the manufacturer and a third-party lab test report covering alkali resistance and glass transition temperature (Tg).

FRP Rebar is ideal for highly corrosive environments such as marine structures (piers, seawalls), bridge decks exposed to de-icing salts, and MRI rooms or power plants due to its non-conductive and non-magnetic properties. It is also significantly lighter, reducing transportation and handling costs on-site.

The most common treatments are sand-coated, ribbed, or wrapped surfaces. A sand-coated finish provides the highest bond strength with concrete, ensuring the rebar does not slip under load. Ribbed profiles are standard for mechanical interlocking, similar to traditional steel.

Request a pre-shipment inspection (PSI) to verify the bar diameter and surface consistency. Since FRP cannot be reshaped on-site, ensure the cutting and bending (if using bent bars/stirrups) are done precisely at the factory according to your BBS (Bar Bending Schedule) before shipping.

Focus on the Total Cost of Ownership (TCO). While the unit price might be higher than steel, negotiate based on volume discounts (typically 10-20% for full container loads) and emphasize the reduced logistics costs due to the material being 1/4 the weight of steel. Use Made-in-China.com to compare verified manufacturers with 'Audited Supplier' status.

FRP Rebar is susceptible to UV degradation if exposed for long periods; ensure the supplier uses UV-protective packaging for transit. For transaction security, utilize secured payment terms (like LC or Escrow) and clearly define the Incoterms (FOB or CIF) to establish where the risk transfers during the cross-border journey.
