Product details
Technical Specifications of Steel Reinforcement Bars for Road Construction
| Property | Parameter | Description |
|---|---|---|
| Product Name | Steel Reinforcement Bars for Road Construction | Deformed and plain steel rebar used in road base, pavement slabs, bridges, and highway infrastructure |
| Material Grade | Grade 60 / HRB400 / B500B / SD390 | International equivalents: ASTM A615 Gr.60, GB/T 1499.2 HRB400, EN 10080 B500B, JIS G3112 SD390 |
| Standard Compliance | ASTM A615 / A706, GB/T 1499.2, EN 10080, JIS G3112, BS 4449 | Meets major international standards for structural and road reinforcement applications |
| Chemical Composition – Carbon (C) | ≤ 0.30% | Controls hardness and weldability; lower C improves ductility for seismic and road load conditions |
| Chemical Composition – Manganese (Mn) | 0.60% – 1.60% | Enhances tensile strength and hardenability of the rebar |
| Chemical Composition – Phosphorus (P) | ≤ 0.045% | Kept low to prevent brittleness and cold-shortness |
| Chemical Composition – Sulfur (S) | ≤ 0.045% | Minimized to avoid hot-shortness and reduce inclusion defects |
| Chemical Composition – Silicon (Si) | 0.17% – 0.80% | Acts as deoxidizer; improves strength and corrosion resistance |
| Tensile Strength | ≥ 600 MPa (Gr.60 / HRB400) | Per ASTM A615: min. 90 ksi (620 MPa); per GB/T 1499.2 HRB400: min. 540 MPa |
| Yield Strength | ≥ 400 MPa – 520 MPa | ASTM A615 Gr.60: min. 60 ksi (420 MPa); HRB400: min. 400 MPa; B500B: min. 500 MPa |
| Elongation | ≥ 9% – 16% | Minimum elongation at fracture; higher values ensure ductility under dynamic road loads |
| Diameter Range | 6 mm – 50 mm (No.3 – No.18) | Common road construction sizes: Ø8, Ø10, Ø12, Ø16, Ø20, Ø25, Ø32 mm |
| Length | 6 m, 9 m, 12 m (custom available) | Standard mill lengths; cut-to-length service available per project specification |
| Surface Finish | Deformed (ribbed) / Plain round | Deformed bars with transverse ribs for superior concrete bond; plain bars for specific slab applications |
| Application | Road pavements, highway bridges, tunnels, retaining walls, drainage structures | Suitable for reinforced concrete road slabs, median barriers, culverts, and foundation works |
| Certification | ISO 9001, CE Marking, Mill Test Certificate (MTC) per EN 10204 3.1 | Third-party inspection available; certificates traceable to heat and lot number |
| Packaging | Bundled in 2–5 MT bundles, steel-strapped | Bundles tagged with grade, heat number, and standard; seaworthy export packing available |
| MOQ | 25 MT per size/grade | Mixed container orders accepted; bulk project quantities negotiable with mill-direct pricing |
Steel Reinforcement Bars for Road Construction | Mill Direct
Steel reinforcement bars for road construction serve as the structural backbone of modern highway, expressway, and urban road infrastructure projects. Engineered to withstand extreme dynamic loads, temperature fluctuations, and long-term stress cycles, these rebar products are indispensable for reinforced concrete pavements, bridge decks, retaining walls, and drainage structures. Sourcing mill-direct ensures that contractors and project developers receive consistent mechanical performance verified against international standards such as ASTM A615, BS 4449, and GB/T 1499.2. Our manufacturing facilities maintain rigorous quality control at every production stage — from raw billet selection through hot-rolling to final surface deformation — delivering rebars that meet the precise tensile, yield, and elongation benchmarks demanded by civil engineering specifications. Whether your project involves a high-traffic arterial road, a highway interchange, or a rural road rehabilitation scheme, selecting the correct grade and diameter of steel reinforcement bars for road construction is critical to long-term pavement durability and structural safety.
What are Steel Reinforcement Bars for Road Construction?
Steel reinforcement bars for road construction — commonly called rebar — are deformed or plain steel bars embedded within concrete to absorb tensile and shear forces that concrete alone cannot resist. Produced from carbon or low-alloy steel billets via hot-rolling, they feature surface ribs that maximize mechanical bond with surrounding concrete, preventing cracking, settlement, and structural failure under repetitive traffic loading and environmental stress.
