20mm Rebar for Sale | High-Strength Steel for Construction

20mm rebar for sale refers to reinforcing bars with a nominal diameter of 20mm (0.79 inches), a popular choice for medium to heavy duty construction due to its balance of strength and workability. Manufactured from grades like HRB 400 (400 MPa yield), ASTM A615 Grade 60 (414 MPa), or BS 8666 Grade 500B, these rebars are hot rolled with rib patterns designed to meet regional bond strength requirements (e.g., minimum 1.2MPa bond stress in GB/T 1499.2). Key applications include: reinforced concrete beams, column reinforcements in mid rise buildings, and foundation piles in commercial projects. Suppliers offer both uncoated and coated options: epoxy coated for marine environments (ASTM A775), galvanized for moderate corrosion (ASTM A767), and bare steel for dry climates. Value added services include: 1) cutting to project lengths (tolerance ±5mm); 2) bending into L/ U shapes for corner reinforcements; 3) bundled packaging (2–3 tons per bundle) with moisture resistant wrapping for overseas shipment. Compliance documentation includes mill test reports (MTR), certification of conformity to target standards, and third party inspection certificates (SGS, Bureau Veritas), facilitating customs clearance and project approval. The global market for 20mm rebars is driven by infrastructure growth in emerging markets, with suppliers offering competitive pricing through economies of scale and direct mill partnerships, ensuring consistent quality and timely delivery for large scale projects.
