10 mm Reinforcing Steel Coil
DIN 488 / EN 10080-compliant 10 mm rebar coil in grades B500A and B500B — 0.617 kg/m, hot- or cold-rolled, in 2–3 t coil weights. The versatile mid-range coil size for stirrup bending, mesh welding, and structural reinforcement. Export-ready with Mill Test Certificate.
10mm Rebar Coil: Technical Specification
The 10 mm reinforcing steel coil sits at the mid-range of the coil product family — heavier than the 8 mm wire used in mesh production, yet still compact enough for continuous coil processing on CNC stirrup benders. At 0.617 kg per linear metre and a cross-sectional area of 78.5 mm², it delivers meaningful structural contribution as stirrups in beams and columns, as well as secondary reinforcement in walls and slabs.
Steel Rebar Germany supplies 10 mm coil to DIN 488 and EN 10080 in grades B500A (normal ductility, 500 MPa yield, k ≥ 1.05, Agt ≥ 2.5%) and B500B (high ductility, k ≥ 1.08, Agt ≥ 5.0%). Both grades carry the German legacy designation BSt 500. The 10 mm diameter is frequently specified in European and export-market structural drawings where 8 mm stirrups are undersized and 12 mm is unnecessarily heavy.

10 mm Coil vs Straight Bar: When to Specify Coil
For 10 mm diameter, the choice between coil and straight bar depends on production method. Coil is ideal when the bar will be processed through automated stirrup bending machines or fed into a straightening-and-cutting line on site. It eliminates the offcut waste generated by fixed-length bars and enables continuous high-speed processing. Straight bar at 6–12 m lengths may be preferred for manual bending operations or where coil-straightening equipment is unavailable.
Explore our coil vs straight bar comparison or view the B500B straight bar range for projects requiring fixed lengths.
Grade Selection for 10 mm Coil
B500A: Cold-rolled, normal ductility (Agt ≥ 2.5%). Suited for applications not requiring high ductility class — mesh cross-bars, light stirrups, distribution reinforcement. Tight dimensional tolerances from the cold-rolling process.
B500B: Hot-rolled, high ductility (Agt ≥ 5.0%, k ≥ 1.08). Required when the structural design specifies ductility class B under Eurocode 2 or equivalent national standard. The B500B hot-rolled surface provides enhanced bond with concrete and is the standard choice for load-bearing stirrup applications in seismically active regions.
Applications of 10 mm Rebar Coil
Structural and manufacturing uses where 10 mm coil is commonly specified.
Beam & Column Stirrups
10 mm is a common stirrup diameter in medium-span beams and columns — coil format enables fast CNC production of closed rectangular and spiral stirrup forms.
Slab Reinforcement
Used as main or distribution reinforcement in reinforced concrete slabs, flat plates, and raft foundations where higher cross-section than 8 mm is needed.
Foundation Applications →Precast Production
Precast manufacturers use 10 mm coil as stirrup reinforcement in precast beams, columns, and wall panels — high throughput with coil-fed bending machines.
Precast Applications →Bridge & Infrastructure
Shear reinforcement in bridge decks, retaining walls, and tunnel linings frequently specifies 10 mm stirrups at defined spacing per EC2 design.
Infrastructure Applications →High-Rise Construction
Core walls and shear walls in tall buildings use 10 mm coil-fed stirrups at close centres — ductility class B500B supports seismic design requirements.
High-Rise Applications →Export Projects
Full documentation package — MTC, Certificate of Origin, CE/DoP — supplied with every export consignment. Container and break-bulk shipment available.
Export & Delivery →Coil Weight and Logistics for 10 mm
A standard 2-tonne coil of 10 mm rebar contains approximately 3,241 linear metres, calculated from the 0.617 kg/m unit weight. This provides a substantial processing run before reel change on automated equipment. For large-volume export orders, multiple coils are bundled into seaworthy units for container loading.
We confirm exact coil weights, bundle configuration, and packing dimensions at quotation stage. Consignments are supplied with:
- EN 10204 3.1 Mill Test Certificate (chemical + mechanical test results, heat traceability)
- Certificate of Origin for customs and LC compliance
- CE Marking / Declaration of Performance where applicable
- Full packing list with net and gross weights
