The 16mm rebar price (nominal diameter 16mm, ~0.63 inches) is a benchmark in the construction industry, widely used in residential, commercial, and light industrial projects for its balance of strength and cost. Prices vary by region, grade, and coating: in China, HRB 400 16mm rebars range from CNY 3,800–4,500/ton (\(550–\)650/ton), influenced by billet prices and government steel production policies. In North America, ASTM A615 Grade 60 16mm rebars are priced at US\(750–\)850/ton, reflecting higher alloy content and compliance with OSHA safety standards. Key cost components include: 1) material: microalloyed steels for high strength grades add \(50–\)80/ton; 2) coating: hot dip galvanization adds \(100–\)150/ton, while epoxy coating (ASTM A775) adds \(180–\)250/ton; 3) logistics: inland transportation ( \(20–\)50/ton) and import duties (5–15% in markets like India). Price fluctuations are driven by seasonal demand (peak in Q2/Q3 for construction) and global events (e.g., COVID 19 lockdowns caused a 20% price spike in 2021 due to supply chain disruptions). Suppliers often provide price alerts for contract clients, along with hedging options to mitigate raw material volatility, ensuring predictability in project budgeting for mid sized constructions like apartment complexes or retail buildings.
