Reinforcing steel bar ASTM A615 Grade 60

Description

1. Product Overview
This deformed reinforcing steel bar is manufactured to ASTM A615 Grade 60, offering a minimum yield strength of 60,000 psi (420 MPa) for reinforced concrete structures. It is primarily used in building foundations, highway pavements, precast concrete elements, and water-retaining structures. The key value proposition is predictable mechanical performance under tension and shear, reducing over-engineering and material waste. Strategically, it remains the most specified rebar grade in North American and Middle Eastern infrastructure markets due to its balance of strength, ductility, and weldability.

2. Key Specifications & Technical Characteristics

• Material composition: Low-carbon steel (max C 0.30%, Mn 0.60–1.10%, P ≤ 0.04%, S ≤ 0.05%)

• Grade / standard: ASTM A615 Grade 60 (420 MPa yield strength)

• Physical form: Deformed (ribbed) bars with two longitudinal ribs and transverse deformations

• Diameter range: #3 (10 mm) to #18 (57 mm)

• Color: Mill scale dark grey (uncoated) / optional epoxy coating available upon request

• Density: 7.85 g/cm³

• Packaging options: Bundled with 4 to 6 steel ties (bundle weight 1.5–3.0 MT), or loose bundles for container loading

• Shelf life: Indefinite when stored dry, off-ground, and protected from salt exposure

3. Core Industrial Applications

• Heavy civil engineering: Bridge piers, box culverts, retaining walls – outperforms plain bar through ≥12% elongation post-yield, preventing brittle failure.

• Commercial & residential high-rises: Column and beam reinforcement – reduces congestion compared to Grade 40, allowing faster cage assembly.

• Precast concrete manufacturing: Prestressed and non-prestressed elements – consistent bendability reduces rejection rates versus off-grade imports.

• Energy & marine structures: Wind turbine foundations, port terminals – wider bend radius tolerance (3x bar diameter) prevents cracking in highly reinforced sections.

4. Competitive Advantages

• Quality consistency: Mill test certificates (MTC) provided per heat – third-party inspected for ASTM compliance with ≤2% CV in yield strength across 2,000+ MT lots.

• Supply reliability: Dual mill sourcing (domestic + secondary strategic mill) ensures 98% on-time-in-full (OTIF) delivery even during peak construction seasons.

• Logistics capability: Bagged or loose bundle LCL/FCL – direct to job site or warehouse; rail/sea/road multimodal routing pre-optimized.

• Price competitiveness: 5–8% below average spot price for full container loads (FCL) via direct mill allocation, no broker markup.

• Sustainability: 97% recycled content + EPD available upon request – qualifies for LEED v4 MR Credit.

• Technical support: In-house PE-stamped lap splice and embedment length schedules provided free for orders ≥100 MT.

5. Commercial & Supply Information

• Minimum Order Quantity (MOQ): 20 metric tons (BULK)

• Loading capacity per 20’ general purpose container: ~22 MT (depending on bar diameter)

• Loading capacity per 40’ general purpose container: ~25 MT
