| Property | Parameter | Description |
|---|---|---|
| Product Name | Corrosion Resistant Rebar Materials | High-performance reinforcing bar engineered for superior corrosion resistance in aggressive environments |
| Material Grade | ASTM A1035 Grade 100/120; 316L Stainless Rebar; MMFX2 (Micro-composite Steel); Epoxy-Coated Rebar Grade 60 | Equivalent international grades: EN 1.4404 (316L), GB/T 1499.2 HRB400E; chromium-alloy and stainless steel variants available |
| Standard Compliance | ASTM A1035 / A1035M; ASTM A955 / A955M; ASTM A775 / A775M; EN 10080; GB/T 1499.2 | Covers low-carbon chromium steel, stainless steel, and epoxy-coated deformed reinforcing bars |
| Chemical Composition (Cr-alloy) | C ≤ 0.15%; Mn ≤ 1.50%; Cr: 8.0–10.9%; Si ≤ 0.50%; P ≤ 0.035%; S ≤ 0.045% | High chromium content forms passive oxide layer; low carbon minimizes sensitization and weld decay |
| Chemical Composition (316L SS) | C ≤ 0.03%; Cr: 16.0–18.0%; Ni: 10.0–14.0%; Mo: 2.0–3.0%; Mn ≤ 2.0%; P ≤ 0.045%; S ≤ 0.030% | Molybdenum addition enhances pitting and crevice corrosion resistance in chloride-rich environments |
| Tensile Strength | ≥ 1035 MPa (ASTM A1035 Gr.150); ≥ 690 MPa (ASTM A955 316L); ≥ 520 MPa (Epoxy-coated Gr.60) | Significantly higher tensile capacity vs. conventional carbon steel rebar (ASTM A615 Gr.60: ≥ 620 MPa) |
| Yield Strength | ≥ 862 MPa (ASTM A1035 Gr.125); ≥ 517 MPa (ASTM A955 316L); ≥ 414 MPa (Epoxy-coated Gr.60) | High yield-to-tensile ratio allows reduced rebar quantity in design, lowering overall project cost |
| Elongation | ≥ 7% (ASTM A1035); ≥ 12% (ASTM A955 316L); ≥ 9% (Epoxy-coated) | Measured over 8-inch (200 mm) gauge length per ASTM standards; ensures adequate ductility for seismic zones |
| Bar Diameter Range | #3 – #18 (9.5 mm – 57.3 mm); Metric: 10 mm – 50 mm | Standard deformed bar profiles; custom sizes available upon request for specialized structural applications |
| Length | Standard: 6 m / 12 m; Custom: up to 18 m | Mill-cut or saw-cut lengths; cut-to-length service available with tolerance ±25 mm |
| Surface Finish | Deformed (ribbed) surface; Epoxy coating (ASTM A775); Fusion-bonded epoxy; Bare bright finish (SS grade) | Deformed ribs enhance mechanical bond with concrete; epoxy coating thickness: 130–300 µm per ASTM A775 |
| Corrosion Performance | Chloride threshold: 5–15× higher than black steel; Salt spray resistance: ≥ 1000 hrs (ASTM B117) | Suitable for marine structures, bridge decks, coastal highways, wastewater treatment plants, and parking garages |
| Application | Marine infrastructure, bridge decks, coastal buildings, tunnels, water treatment facilities, highway pavements, seismic structures | Ideal where chloride-induced corrosion, carbonation, or chemical exposure significantly reduces service life of conventional rebar |
| Certification | ISO 9001:2015; Mill Test Certificate (MTC) per EN 10204 3.1/3.2; AISC; ACI 318 compliant | Full traceability documentation provided; third-party inspection by SGS, Bureau Veritas, or TÜV available on request |
| Packaging | Hexagonal bundles: 1–3 MT per bundle; steel-strapped; waterproof kraft paper wrapping for epoxy-coated bars | Bundle tags include heat number, grade, standard, and diameter; sea-worthy export packing available |
| MOQ | 5 MT per grade/size combination; 25 MT for full container load (FCL) | Mixed grades accepted for LCL shipments; stock items available for immediate dispatch within 7 business days |
Initial size mix-up on galvanized rebar order — resolved satisfactorily after follow-up
We ordered 30 tons of ASTM A767 Class I galvanized rebar split between #4 and #6 bars for a port quay wall in Mumbai. The first delivery contained an incorrect ratio — more #4 than specified in the purchase order. This created a short delay while we awaited the correct #6 quantity. To their credit, the supplier acknowledged the picking error quickly, arranged priority dispatch of the balance stock, and provided a partial credit on freight costs. Final material met the 420 MPa yield specification and zinc coating weight requirements per the MTRs. Issue resolved, and we would consider using them again with clearer order confirmation steps.
