Hot-Rolled Carbon Steel Bars - ASTM A615 Grade 60 Structural Rebar

Technical Specifications of Hot-Rolled Carbon Steel Bars

Hot-Rolled Carbon Steel Bars - ASTM A615 Grade 60 Structural Rebar

Hot-rolled carbon steel bars represent a fundamental structural material extensively employed across construction, manufacturing, and infrastructure projects worldwide. These deformed reinforcing bars are produced through a thermomechanical rolling process at temperatures exceeding 1700°F, resulting in superior mechanical properties and cost-effective performance for concrete reinforcement applications. Engineered to meet stringent industry standards including ASTM A615/A615M-20, these bars serve critical roles in commercial buildings, bridges, highways, and heavy industrial facilities where reliable tensile strength and ductility are non-negotiable requirements.

What is Hot-Rolled Carbon Steel Bars?

Hot-rolled carbon steel bars are deformed reinforcing steel products manufactured by heating steel billets above their recrystallization temperature and subsequently passing them through precision rolling mills to achieve specified dimensional tolerances and mechanical characteristics. The thermomechanical processing imparts a characteristic mill scale surface finish and enhanced grain structure, delivering yield strengths ranging from 60,000 psi (Grade 60) to 80,000 psi (Grade 80) per ASTM specifications.

Hot-Rolled Carbon Steel Bars Technical Specifications

Our mill-direct hot-rolled carbon steel bars comply with ASTM A615/A615M-20 Section 6 chemical composition requirements, featuring carbon content of 0.30% maximum for weldable grades. Grade 60 bars exhibit minimum yield strength of 60,000 psi (420 MPa) and tensile strength of 90,000 psi (620 MPa) with elongation values of 9% minimum in 8-inch gauge length per ASTM E8 testing protocols. Available diameter ranges span from #3 (⅜") through #18 (2¼") bars, manufactured to standard lengths of 20 feet, 40 feet, and 60 feet with deformation pattern spacing conforming to ASTM A615 Section 7.4.1 geometry requirements.

Frequently Asked Questions

What is the minimum order quantity (MOQ)?

Our standard minimum order quantity is 20 metric tons per specification and size, though we accommodate smaller quantities for established accounts or multi-grade shipments. Consolidated orders combining multiple bar sizes can meet the 20-ton threshold while optimizing freight economics for your project requirements.

Do you provide material test certificates?

Yes, we furnish certified mill test reports (MTRs) compliant with ASTM A615 Section 15 documentation requirements for every shipment. These certificates include heat-specific chemical analysis results, mechanical property test data, heat number traceability, and third-party inspection stamps when specified. Digital MTR copies are available through our online portal within 24 hours of shipment.

What is the typical delivery time?

Stock sizes (#4 through #11 bars in Grade 60) ship within 5-7 business days from our regional distribution centers. Custom lengths, special grades, or large-volume orders require 3-4 weeks production lead time from mill scheduling. Expedited processing is available for critical-path projects with premium freight arrangements to jobsite locations.

Can you cut to custom sizes?

Our fabrication division provides precision cutting services to project-specific dimensions with tolerances of ±½ inch on lengths up to 60 feet. We also offer value-added services including bar bending per ACI 315 schedules, epoxy coating application meeting ASTM A775 Class A standards, and bundling configurations optimized for crane handling at construction sites.
