Nikasteel supplies continuous-cast square billets 100×100 to 150×150 mm in 3SP/5SP, Q235 and 20MnSi grades through our partner mills — 6 m lengths by container (25–27 t) or 6/12 m break-bulk cargoes, with EN 10204 3.1 mill certificates. Regular destinations: Egypt, Algeria, Morocco, Tunisia and West Africa re-rolling mills.
Re-rolling mills live on billet. When scrap prices spike or local casting capacity falls short, mills in North and West Africa import square billets to feed their rebar and wire-rod lines — and Chinese mills are the flexible swing supplier. This page lays out the billet spec system so your inquiry comes back priced fast.
Billet Sizes We Supply
| Section (mm) | Weight (kg/m) | Ton per 6 m Piece | Typical Product After Re-rolling |
|---|---|---|---|
| 100 × 100 | 78.5 | 0.47 t | 8–12 mm rebar, wire rod |
| 120 × 120 | 113.0 | 0.68 t | 10–16 mm rebar |
| 130 × 130 | 132.7 | 0.80 t | 12–18 mm rebar |
| 150 × 150 | 176.6 | 1.06 t | 16–25 mm rebar, sections |
| 150 × 250 (bloom) | 294.4 | 1.77 t | Large sections, beams |
Lengths: 6 m standard for container cargo; 9–12 m for break-bulk vessels feeding larger mills.
The 3SP / 5SP Grade System — What African Mills Ask For
| Grade | Carbon | Mn | Character |
|---|---|---|---|
| 3SP | 0.14–0.22% | 0.40–0.65% | Standard re-rolling billet — good ductility for rebar |
| 5SP | 0.28–0.37% | 0.50–0.80% | Higher strength — for high-yield rebar lines |
| Q235 | ≤ 0.22% | ≤ 1.40% | Chinese general structural grade |
| 20MnSi | 0.17–0.25% | 1.20–1.60% | Higher Mn — feeds high-strength rebar (HRB400) lines |
Tell your mill's product mix (rebar sizes and strength class) and we will match the billet grade — ordering 5SP when the line makes 3SP-grade rebar wastes money, and the reverse loses strength.
Logistics: Container vs Break-Bulk
- Container (trial / small mills): 6 m billets in 40GP — 25–27 t per box, bundles of 1.5–2 t, easy discharge at ports without bulk handling.
- Break-bulk (working mills): 500–2,000 t parcels, 6/9/12 m lengths, geared vessels or port cranes. Freight per ton drops sharply at this scale.
- Ports we serve regularly: Alexandria & Dekheila (Egypt), Algiers (Algeria), Casablanca (Morocco), Tunis (Tunisia), Benghazi, plus Dakar, Tema, Lagos and Mombasa further south.
- Documents: CI, PL, BL, CO and EN 10204 3.1 mill certificate per heat — the paper your customs broker and quality lab both need.
Four Checks Before Booking a Billet Cargo
- Grade on the MTC: the certificate must name 3SP/5SP (or your specified grade) with heat chemistry — "equivalent" is not a grade.
- Dimensional check at loading: billet tolerance runs ±3–5 mm on section; agree inspection at loading port (SGS/BV) for large parcels.
- Length mix: confirm 6 m ±50 mm vs exact lengths — mill rolling schedules vary.
- Payment terms by parcel size: containers run T/T 30/70; break-bulk cargoes commonly L/C at sight.
