What Sidenor does

Sidenor (Société des Aciéries de Tunisie) is a Tunisian private steel manufacturer founded in 1993, operating as a wholly-owned subsidiary of the diversified conglomerate Groupe Mokhtar. It is positioned as the first private rolling mill in Tunisia, with a stated production capacity of 200,000 tonnes per year. The company runs a single-site integrated hot-rolling mill in Tunis equipped with a latest-generation, fully-automated DANIELI rolling line, processing purchased steel billets into a focused three-product portfolio: RB500W ribbed rebar in straight bars (8–32 mm), RB500W ribbed rebar coils for prefabricated reinforcement, and fil machine / wire rod (5.5–16 mm) in 1.4–2 tonne coils for downstream drawing, welded mesh, and pre-assembled reinforcement. All products are manufactured under an INNORPI licence for the Tunisian standard NT 26.05 (2004), equivalent to ISO 6935-02 (1997), and the RB500W grade carries tight chemistry caps (C ≤ 0.22%, Ceq ≤ 0.50%) for seismic-resistant, weldable rebar. A proprietary SID marking engraved approximately every metre along each bar plus bundle-level labelling enables end-to-end traceability from mill to construction site, and an on-site laboratory performs geometric, mechanical (tensile, bending/unbending), and chemical inspection on every batch.

Sidenor sells exclusively on the Tunisian domestic market via a direct B2B motion: customers — wholesale building-materials merchants and industrial processors — submit a written commercial file to the Commercial Director (legal status, tax ID, commercial registry, bank RIB) before annual supply terms are approved. RB500W rebar pricing is state-homologated in Tunisia and aligned with the prevailing RB400 market price, so Sidenor has limited individual pricing power and revenue tracks the Tunisian construction cycle. Marketing is event-driven rather than digital: the company maintains a regular presence at Tunisian construction trade shows (CARTHAGE, BTP EXPO, Journées Eco-construction, Salon Bâtiment de Sousse) and the Mediterranean MEDIBAT show in Sfax, supplemented by a basic corporate website, Facebook, and LinkedIn pages. Distribution runs directly from the Tunis mill to customers; no third-party resellers, e-commerce channel, or export sales operation is referenced.

The company is supported by its parent Groupe Mokhtar — a Tunisian industrial group with sister operations in food commodities (Carthage Grains, 600,000 t/year soybean crushing) and metal construction (Carthage Industries) — which provides industrial, financial, and reputational backing with more than 20 years of credibility with funders and partners. Sidenor has held the AFCAB French reinforcing-steel certification consecutively in 2021 and 2022 and consecutive INNORPI re-certifications through 2018 and 2019, with an additional D32 mm diameter licence. No public listing, equity financing rounds, acquisitions, or leadership changes are disclosed; cap-table detail beyond the parent-subsidiary relationship is a data gap.

Revenue model

1. Steel product sales (rebar and wire rod): Core revenue comes from selling hot-rolled steel products — RB500W rebar in bars and coils and fil machine (wire rod) — to wholesale building-materials merchants and industrial users in Tunisia. Prices for RB500W are homologated in Tunisia and aligned with the prevailing RB400 market price. Revenue tied directly to construction-sector demand and production capacity (~200,000 tonnes/year).

Core offering

Sidenor operates an integrated hot-rolling steel mill producing three core long steel products — RB 500W high-bond ribbed rebar in bars, RB 500W ribbed rebar in coils, and round smooth wire rod (fil machine) — from purchased steel billets. All products are manufactured in compliance with Tunisian standard NT 26.05 (2004) equivalent to ISO 6935-02 (1997), serving the Tunisian construction and industrial processing sectors at an annual production capacity of 200,000 tonnes.

Product overview

Sidenor is a single-product-line steel manufacturer offering a focused portfolio of three core hot-rolled steel products — Ronds à béton nervuré (RB 500W ribbed rebar bars), Fil machine (round smooth wire rod), and Ronds à béton en bobines (RB 500W ribbed rebar coils). All three are produced on the same hot-rolling mill from purchased steel billets, in compliance with Tunisian standard NT 26.05 (2004) and the equivalent international ISO 6935-02 (1997), with the company's production process and quality control spanning from raw material supply (billettes d'acier) through finished product inspection. As the first private rolling mill in Tunisia with an annual production capacity of 200,000 tonnes, Sidenor positions its ribbed rebar (RB 500W) and wire rod (Fil machine) as complementary offerings for the construction and industrial sectors, including welded mesh, pre-assembled reinforcement, and prefabrication applications.
