8 mm Reinforcing Steel Coil
DIN 488 / EN 10080-compliant 8 mm rebar coil in grades B500A and B500B — 0.395 kg/m, hot- or cold-rolled, in 2–3 t coil weights. Ideal for automated stirrup bending and mesh welding machines. Export-ready with Mill Test Certificate.
8mm Rebar Coil: Technical Specification
The 8 mm reinforcing steel coil is one of the most widely used diameters in the coil format — valued by prefabrication plants and stirrup-bending operators alike for its combination of flexibility and structural contribution. At 0.395 kg per linear metre and a cross-sectional area of 50.3 mm², it delivers reliable reinforcement in wall ties, column stirrups, slab distribution reinforcement, and automated mesh production.
Steel Rebar Germany supplies 8 mm coil to DIN 488 and EN 10080 in grades B500A (normal ductility, characteristic yield 500 MPa, k ≥ 1.05, Agt ≥ 2.5%) and B500B (high ductility, k ≥ 1.08, Agt ≥ 5.0%). Both grades carry a 500 MPa minimum yield strength. B500A is most common in the cold-rolled coil format used for mesh and light stirrups; B500B hot-rolled coil suits load-bearing stirrup production where higher ductility reserve is specified.

Why Choose Coil Format Over Straight Bar for 8 mm?
Coil supplies continuous wire without bar-end offcuts, making it the preferred feedstock for CNC stirrup bending machines and automatic mesh welding lines. For 8 mm rebar, coil format reduces handling waste, enables high-speed production of closed stirrups, and integrates directly into slab mesh panels without manual cutting. Typical coil weight of 2–3 tonnes provides substantial run-lengths between reel changes on automated lines.
For site applications where straight bar is preferred, see our B500B straight bar range and cut-and-bend stirrup service.
Grade Selection: B500A vs B500B in 8 mm Coil
B500A (cold-rolled coil): Normal ductility (Agt ≥ 2.5%). The dominant grade for automated mesh and light stirrup manufacturing. Cold-rolling refines grain structure and holds tight dimensional tolerances. Suitable for EN 1992-1-1 / Eurocode 2 applications not requiring enhanced ductility class.
B500B (hot-rolled coil): High ductility (Agt ≥ 5.0%, k ≥ 1.08). Required for seismically sensitive regions or where Eurocode 2 specifies ductility class B or above. Hot-rolled surface texture provides superior bond to concrete. Increasingly specified in Middle Eastern, African, and Southern European export markets.
Applications of 8 mm Rebar Coil
Where 8 mm coil is specified in structural and precast concrete production.
Stirrup Production
Continuous coil feed for CNC stirrup benders producing column and beam stirrups at high throughput — no offcut waste from bar lengths.
Welded Mesh Manufacturing
8 mm coil feeds automatic mesh-welding lines producing standard and bespoke reinforcement panels per DIN 488-4 for slabs and walls.
View Mesh Products →Distribution Reinforcement
Used as distribution / secondary reinforcement in slabs, retaining walls, and foundation mats alongside larger diameter main bars.
Precast Concrete Elements
Precast producers use 8 mm coil for lattice girder cross-members and as cage reinforcement in columns, beams, and hollow-core slabs.
Precast Applications →Infrastructure & Bridges
Shear stirrups in bridge piers and abutments frequently specify 8 mm at tight spacing — coil format enables efficient site-based bending.
Infrastructure Applications →Export Projects
8 mm coil is bundled in seaworthy packaging for container export. We supply Mill Test Certificates and Certificate of Origin for every shipment.
Export & Delivery →Export Documentation and Delivery
Every consignment of 8 mm rebar coil from Steel Rebar Germany is supplied with the full documentation package required for international procurement:
- Mill Test Certificate (MTC) per EN 10204 3.1 — chemical composition, mechanical properties, heat number traceability
- Certificate of Origin — for customs, tariff, and letter-of-credit compliance
- CE Marking / Declaration of Performance (DoP) — where required by destination country
- Packing list — coil count, net/gross weights, bundle dimensions
Coils are strapped in seaworthy bundles and can be loaded into standard 20 ft or 40 ft containers or shipped as break-bulk. Lead times and Incoterms (EXW, FOB, CFR, CIF) are confirmed at quotation stage. Contact us to discuss your port of destination and delivery schedule.
