Industrial Specifications
& ASTM Compliance for GFRP

Every bar we distribute meets ASTM D7957 at minimum, the governing specification for solid round GFRP bars used in concrete reinforcement. This standard sets the baseline for fiber content, tensile strength, modulus of elasticity, degree of cure, and bar dimensions. For projects with tighter engineering demands, we also stock high-strength products rated to ASTM D8505.

Compliance isn’t just a certification on paper. GFRP rebar built to D7957 delivers roughly three times the tensile strength of conventional steel while weighing a fraction as much, which is why precast operators increasingly specify it for structures exposed to moisture, deicing salts, or marine environments. Because the material is non-conductive and corrosion-proof, it eliminates the rust-jacking failures that plague steel reinforcement in these conditions over time.

We only source bars produced with vinyl ester or epoxy resin systems. Polyester-resin products don’t make it onto our shelves, since it falls short of the durability standards our customers need for long-service structures. If your project calls for ICC-ES evaluation reports to support code approval, we can provide that documentation alongside your order to keep your submittal package moving.

#3 Rebar Specifications: Steel and Fiberglass Options

Adelphia Metals distributes #3 rebar in steel and composite fiberglass options. We process more volume for #3 rebar than #4 rebar, making it a cornerstone of our inventory. Both material options feature a 3/8″ nominal diameter.

Steel #3 Rebar Specifications

We supply 3/8” (0.376”) bars in ASTM A615 Grade 40, Grade 60, Grade 80, and ASTM A706. Types include standard black steel, epoxy-coated (ASTM A775), and Galvabar galvanized options. We stock these in standard 20 ft., 30 ft., or 40 ft. lengths, and we supply custom cuts.

Fiberglass #3 Rebar (Pinkbar™) Specifications

These 0.375” bars consist of vinyl ester or epoxy resins and strictly avoid polyester. They meet ICC-ES AC454 criteria. Crews frequently utilize this material in flatwork and shrinkage crack mitigation. Due to its high tensile strength and zero-rust properties, a #3 fiberglass bar can replace a #4 steel bar. These composite units weigh up to 75% lighter than steel equivalents.

#4 Fiberglass Rebar Bulk Bundle Options

Most composite reinforcement orders come through for 3/8″ & 1/2″ diameters, and we have built our stocking program around that specific demand. We keep #4 fiberglass rebar in ready stock, packaged in 150-piece bundles for straightforward crane handling and job-site distribution.

Beyond standard #4 fiberglass rebar, we carry straight bar from #3 to #8 in standard lengths of 20 ft., 30 ft., and 40 ft., allowing procurement teams to match bar size to load requirements without waiting on custom factory mill runs. If your project calls for a shape outside that standard, our engineering team sources custom bent bars directly to your drawings.

To simplify site receiving and inventory management, we align our high-volume distribution around standardized bundle and length specifications:

  • Bundle quantities. Standard 150-piece bundles for #3 and #4 fiberglass rebar; Other diameters are bundled proportionally by weight.
  • Stock lengths. Available in 20′, 30′, and 40′ straight lengths, with custom cut-to-length services for major orders.
  • Bend availability. Pre-fabricated 90-degree stirrups and corners ship from stock, while complex geometries are custom-formed to project drawings.

Sourcing Domestic vs. Imported
Fiberglass Reinforcement

One of the first questions we get from procurement managers is whether to buy domestic or imported bars. We stock both, and we quote both on nearly every inquiry, because the right answer depends on your project budget, timeline, and any Buy America requirements attached to public contracts.

The origin of production impacts both lead times and project budgets:

Domestic bar

Carries a premium due to U.S. manufacturing costs, but offers faster shipping and meets domestic-sourcing mandates on public infrastructure contracts.

Imported bar

Provides a lower initial price point for budget-conscious projects while maintaining full compliance with ASTM D7957 through verified mill test reports.

We have built deep relationships across global and domestic markets over three decades in this business, allowing us to shop the market on your behalf. Rather than locking customers into a single supply source, we compare pricing across our network for every order.

We hold quoted prices firm for three months, protecting your project margin from raw material cost spikes. If price and availability drive your decision, we can run side-by-side quotes before you finalize project sourcing.

Through high-volume agreements with certified mills, we help insulate procurement teams from sudden market fluctuations. Navigating the technical parameters of alternative fiberglass rebar manufacturing requires an experienced distribution partner who can vet mill allocations before designs go to print.

Strategic Staging & Nationwide
Distribution Logistics

Material availability only matters if the product arrives on schedule. We distribute high-strength fiberglass rebar from more than 50 locations across the US, a footprint that lets us stage inventory near major precast and infrastructure markets rather than shipping everything from a single regional warehouse.

We leverage large distribution fleet relationships to move the bar quickly once an order is placed. Under normal market conditions, this translates to standard lead times of three to five days from order to delivery. When supply chains tighten industry-wide, we work our supplier network to keep customers close to that window rather than leaving crews waiting.

Financial bottlenecks should not delay a concrete pour, either. We process commercial credit applications within 48 hours so approved customers move straight from quote to contract fulfillment. Plant operators get a single point of technical contact who manages both the engineering spec sheet and the shipping logistics behind it.
