Core Structural Properties: Engineered for Load-Bearing Reliability
As a "deformed" steel bar (distinguished by surface ribs), its primary advantage lies in enhancing structural safety when embedded in concrete. These properties align with global standards (e.g., China’s GB/T 1499.2-2018, ASTM A615 for export) and 2022’s construction quality requirements:
Ribbed Surface for Superior Concrete Bonding The defining "deformed" feature – continuous transverse ribs (spiral, herringbone, or crescent-shaped) on the surface – drastically increases friction and mechanical interlocking with concrete. This prevents slippage between rebar and concrete under loads (e.g., building weight, seismic activity), ensuring the structure acts as a single, stable unit. Rib height, spacing, and shape strictly comply with standards (e.g., GB/T 1499.2) to guarantee consistent bonding performance across 10mm, 12mm, and 16mm diameters.
High Strength for Load-Bearing Demands Most 2022-vintage rebars of these sizes use the HRB400 grade (the global construction standard) or HRB500 (high-strength option), with mechanical properties meeting critical safety thresholds:
Tensile strength: ≥540 MPa (HRB400) / ≥630 MPa (HRB500) – prevents brittle fracture during sudden stress (e.g., earthquakes, heavy impacts).
Elongation: ≥16% (HRB400) – ensures ductility, allowing controlled deformation before failure (a key factor in seismic resilience, mandatory in 2022’s building codes for high-risk zones).
Durability for Long-Term Structure Life Made from low-carbon alloy steel (with micro-additives like vanadium or niobium), these rebars resist oxidation during storage and construction (via factory-applied rust removal, e.g., shot blasting to eliminate scale). Once embedded in concrete, the alkaline environment of concrete forms a protective film on the rebar surface, preventing corrosion and ensuring the structure’s service life (≥50 years for residential buildings, per 2022 standards).
2022-Era Cost & Market Alignment: Value for Bulk Buyers
In 2022, these rebars’ pricing and availability were shaped by global steel market trends (e.g., raw material costs, supply chain stability) and factory-direct advantages, making them cost-competitive:
Factory-Direct Pricing Benefits 2022’s "factory prices" eliminated middlemen (distributors/agents), reducing markups by 8–15% compared to retail channels. For bulk orders (100+ tons, common in 2022’s infrastructure projects), factories often offered volume discounts – a key factor for cost-sensitive buyers (e.g., state-owned construction firms).
Raw Material Cost Alignment 2022 saw moderate stability in iron ore and coking coal prices (vs. 2021’s volatility), allowing factories to offer predictable pricing for 10mm/12mm/16mm rebars. This stability helped construction companies lock in budgets – critical for long-term 2022 projects (e.g., road expansions, residential complexes).
Low Total Ownership Cost Beyond upfront pricing, their durability (reduced replacement needs) and processability (lower labor costs for cutting/bending) minimized long-term expenses. For example, 2022 projects using these rebars reported 5–10% lower maintenance costs vs. using low-quality "non-standard" rebars (which risk corrosion or structural failure).
