Deformed steel rebar (hot-rolled ribbed steel bar) is a high-strength reinforcing bar used in reinforced concrete structures. Its distinctive ribs, lugs and indentations create a strong mechanical bond with concrete, providing the tensile strength that concrete alone lacks, and delivering excellent ductility, seismic performance and durability.
Core Selling Points: high tensile strength · strong concrete bond · earthquake-resistant · good weldability — the reliable backbone of construction projects worldwide.
Why Choose Us
| Feature | Benefit |
|---|---|
| High Tensile Strength | Supplies the tensile capacity required in reinforced concrete, from residential to heavy-duty infrastructure. |
