10 mm B500B Steel Rebar
10mm rebar is a highly versatile diameter for links, stirrups, light-to-medium slabs and mesh reinforcement — with a nominal mass of 0.617 kg/m and full B500B high-ductility compliance to DIN 488 / EN 10080. Supplied in bar or coil with complete export documentation.
10mm Rebar: Technical Specification (B500B, DIN 488)
The 10 mm diameter reinforcing bar in grade B500B is one of the most common diameters in European reinforced-concrete construction. Compliant with DIN 488 and EN 10080, it delivers a minimum yield strength of 500 MPa with strain-hardening ratio k ≥ 1.08 and uniform elongation at maximum force Agt ≥ 5.0% — confirming high ductility class B. At 0.617 kg/m it sits at the crossover point between small-diameter ancillary reinforcement and structural primary bars, making it exceptionally versatile.
| Property | Value |
|---|---|
| Nominal diameter | 10 mm |
| Nominal mass (weight per metre) | 0.617 kg/m |
| Nominal cross-section area | 78.5 mm² |
| Minimum yield strength (ReH) | 500 MPa |
| Strain-hardening ratio k (Rm/ReH) | ≥ 1.08 |
| Uniform elongation Agt | ≥ 5.0 % |
| Standard | DIN 488 / EN 10080 |
| Bars per tonne (12 m bars) | ≈ 135 bars (≈ 1 621 m total) |
| Available form | Straight bars (6–12 m) · Coil |
Formula verification: kg/m = d²(mm) × 0.00617 = 10² × 0.00617 = 0.617 kg/m. Cross-section A = π/4 × 10² = 78.5 mm².
Typical Applications for 10 mm Rebar
A transition diameter equally at home in ancillary and structural roles across building and civil projects.
Stirrups & Column Links
10mm stirrups provide increased shear capacity versus 8mm in medium-span beams and columns, remaining easy to fabricate by hand or machine bending.
Slabs & Ground Beams
Light-to-medium slabs, ground-bearing slabs and shallow ground beams commonly specify 10mm bars at 150–200 mm centres for economic design.
Walls & Retaining Structures
10mm horizontal and vertical bars are standard in reinforced masonry backing walls and lightly loaded retaining walls.
Coil for Stirrup Machines
10mm B500B coil is compatible with most automated stirrup-bending machines. View rebar coils →
Pile Cage Helicals
Helical reinforcement in bored piles from 450 mm diameter upwards frequently uses 10mm bar. See foundations & piling →
Cut & Bend Elements
10mm B500B is cut and bent to standard shape codes (DIN 488 / BS 8666) for prefabricated cage elements. Cut & bend service →
Weight & Quantity Reference for 10mm Rebar Orders
Planning steel take-offs for export or project procurement requires accurate kg-per-metre data. All values based on the nominal mass of 0.617 kg/m:
| Bar length | Weight per bar | Bars per tonne | Total length per tonne |
|---|---|---|---|
| 6 m | 3.70 kg | ≈ 270 bars | ≈ 1 621 m |
| 12 m | 7.40 kg | ≈ 135 bars | ≈ 1 621 m |
| 18 m | 11.11 kg | ≈ 90 bars | ≈ 1 620 m |
