Steel Rebar Deformed Reinforcing Steel Bar Complete Product Guide
Product Overview: What is Rebar?
Rebar (reinforcing steel bar) is a high-strength steel bar used as a tension device in reinforced concrete and masonry structures. Concrete alone is strong under compression but weak under tension — rebar provides the tensile strength needed to make concrete structures durable, safe, and long-lasting.
Key Product Features:
High Tensile Strength: Yield strength from 400 MPa to 600 MPa depending on grade
Superior Bonding: Deformed surface (ribs/lugs) ensures excellent adhesion with concrete
Multiple Standards Available: ASTM A615, BS 4449, DIN 488, JIS G3112, GB 1499.2
Flexible Supply: Diameters from 6mm to 50mm; standard lengths 6m, 9m, 12m (custom lengths available)
Export Ready: Mill Test Certificate (EN 10204 3.1) provided with every shipment

Application
1. Residential & Commercial Buildings
Rebar is the backbone of modern building construction, used in foundations, columns, beams, slabs, and staircases. Typical diameters: 8mm–16mm for residential, 16mm–32mm for high-rise and commercial structures.
2. Bridges & Highway Infrastructure
Bridge decks, piers, abutments, and highway pavements demand high-strength rebar to withstand heavy traffic loads, wind forces, and temperature variations. Typical diameters: 20mm–40mm (BS B500C / ASTM A706 preferred for seismic zones).
3. Industrial & Heavy Foundations
Factory floors, heavy equipment foundations, and industrial complexes require large-diameter rebar for load distribution. Typical diameters: 25mm–50mm.
4. Marine & Coastal Structures
Docks, seawalls, piers, and offshore platforms require epoxy-coated or stainless steel rebar for superior corrosion resistance in saltwater environments.
5. Tunnels & Underground Structures
Tunnel linings, subway stations, and underground parking use rebar cages to withstand earth pressure and water penetration.
