Rebar Steel (TMT Fe500)

Description

Product Overview:
Rebar Steel (TMT Fe500) is a thermo-mechanically treated reinforcing bar with a minimum yield strength of 500 MPa, designed for concrete reinforcement in heavy civil construction. Its primary industrial use includes structural frameworks for bridges, dams, flyovers, and high-rise buildings. The key value proposition is superior ductility combined with high corrosion resistance, reducing total construction costs by up to 12% through lower steel tonnage requirements. Strategically, it is indispensable for markets undergoing rapid urbanization, where safety standards and lifecycle durability directly impact project financing and insurance terms.

Key Specifications & Technical Characteristics

• Chemical composition: Carbon 0.25–0.30%, Sulphur ≤0.040%, Phosphorus ≤0.040%, Manganese 0.80–1.20%

• Grade: Fe500 (min yield strength 500 MPa; min tensile strength 545 MPa)

• Physical characteristics: Ribbed/deformed dark grey bar; diameter range 8mm–32mm; unit weight 0.395–6.31 kg/m

• Packaging: Tightly bundled with color-coded plastic rings or iron wire; custom cut lengths available (9m or 12m standard)

• Shelf life: Indefinite when stored indoors on dry wooden planks (avoids rust formation)

Core Industrial Applications

• Primary industries: Infrastructure engineering, precast concrete manufacturing, deep excavation shoring, marine construction

• Specific use cases: Earthquake-resistant frame ties, pile caps, foundation raft mats, tunnel linings, port wharfs

• Performance advantage: Thermo-mechanical treatment creates a three-layer microstructure – soft inner core for ductility, tough outer ring for weldability and bendability – unlike cold-twisted bars which become brittle under cyclic loading

• Efficiency & cost: 15–18% less steel tonnage vs. mild steel for same load; reduces rebar cage assembly time due to uniform straightness and rib geometry

Competitive Advantages

• Quality consistency: Every batch tested for yield/ultimate ratio (min 1.10), elongation (min 12%), and bend/rebend performance

• Supply reliability: Dedicated rolling mill capacity of 200,000 MT/year with backup power and raw material inventory for 90 days

• Logistics capability: Just-in-time delivery to project sites via company-owned fleet; rail sidings at two plants

• Price competitiveness: Direct mill pricing with volume rebates; no trader markup

• Sustainability: Produced using electric induction furnaces with 72% recycled scrap; EPD available upon request

• Technical support: Free structural design verification and third-party lab testing coordination

Commercial & Supply Information

• Minimum Order Quantity (MOQ): BULK 20MT (single diameter per order)

• Loading capacity: 25–28 MT per 20ft standard container (depending on bar diameter and packing pattern)
