Siderúrgica de Orinoco

What Siderúrgica de Orinoco does

Siderurgica del Orinoco Alfredo Maneiro (SIDOR) is Venezuela's largest integrated steel producer, a state-owned enterprise operating under the Corporacion Venezolana de Guayana (CVG) holding from its main industrial complex in the Ciudad Guayana / Puerto Ordaz Zona Industrial Matanzas. Founded in 1962, the company runs a fully vertical production chain from iron ore agglomeration (pelletizing) through Midrex direct reduction, electric arc furnace steelmaking with EBT tapping, continuous casting, hot and cold rolling mills, and seamless tube manufacturing, yielding an installed liquid steel capacity of 3.6 million tonnes per year following completion of Plan 4. Its product portfolio spans primary products (fired pellets), semi-finished goods (ingots, slabs, billets), flat products (hot-rolled coils, cold-rolled sheet, tinplate, electrolytic chromium-coated steel, annealed sheet), long products (rebar/cabillas and wire rod), and tubular products (seamless casing pipe, line pipe, and TPC tube blanks for couplings).

SIDOR's primary customers operate in four verticals: oil and gas (OCTG, line pipe, couplings for Venezuelan petroleum operations), construction (rebar and structural products for reinforced concrete and infrastructure), industrial and manufacturing (wire rod and semi-finished feedstock), and steel rerollers (billets, slabs, wire rod for further processing). Distribution is conducted through a B2B direct-sales model coordinated by the Direccion General de Ordenes y Logistica (Digol), supported by a Webservice client ordering portal, modernized weighing stations (including the 100,000-tonne-capable Balanza Comercial 3), and port (muelle) infrastructure that supports both domestic Venezuelan dispatch and export shipments to Brazil and Colombia.

Pricing is quotation-based for industrial B2B customers and is not publicly disclosed. In February 2025, SIDOR received ISO 9001-2015 certification from Fondonorma covering design, commercialization, technical assistance, and manufacturing of pellets, billets, wire rod, and carbon steel bars; in March 2025, the company signed investment MoUs with Chinese partners Zhongshe Foreign Co. (seamless tube factories) and Puentes Gran Muralla (bridge construction steel) during Expo Metal 2025. Revenue is not disclosed in available sources, and the company operates without private shareholders as part of Venezuela's national industrial policy under CVG coordination.

Core offering

SIDOR is an integrated steel manufacturer producing pellets (iron ore agglomerates for direct reduction), semi-finished steel (ingots, slabs, billets), flat products (hot-rolled bands, cold-rolled sheet, tinplate, ECCS, annealed products), long products (rebar/cabillas, wire rod/alambrón), and tubular products (line pipe, casing, TPC blanks). The company operates a full vertical process from pelletizing and Midrex direct reduction through electric arc steelmaking, continuous casting, rolling, and tube manufacturing, supplying construction, industrial, and oil & gas customers domestically and in export markets.

Product overview

Siderúrgica del Orinoco Alfredo Maneiro (SIDOR) is Venezuela's largest steel producer, operating as an integrated steel mill. The company manufactures a comprehensive portfolio of steel products organized into four main categories: Primary Products (pellas/pellets for direct reduction), Semi-Finished Products (lingotes/ingots, planchones/slabs, palanquillas/billets for further processing), Flat Products (hot-rolled and cold-rolled products including tinplate/ECCS/annealed sheets), and Long Products (construction bars/rebars and wire rod). The product range also includes tubular products for the petroleum industry (line pipes, casing pipes, and TPC tube blanks). SIDOR's production process encompasses iron ore agglomeration (pelletizing), direct reduction, steelmaking via electric arc furnace, continuous casting, and rolling operations for both flat and long products.

Products and services

• Pellas (Iron Ore Pellets) Spherical agglomerates produced from iron ore concentrates with uniform size distribution, high iron content, high mechanical strength, and good performance under reducing atmospheres; used as feedstock in direct reduction processes.
• Lingotes (Ingots) Semi-finished steel products cast into molds, intended for further processing through rolling or forging.
• Planchones (Slabs) Semi-finished steel products of rectangular cross-section used as feedstock for flat rolling mills to produce hot-rolled and cold-rolled products.
• Palanquillas (Billets) Semi-finished steel product of square cross-section with round corners and maximum area of 23,200 mm², used for rolling into bars, wire rod, and structural products.
• Laminados en Caliente (Hot-Rolled Products) Flat steel products reduced to final thickness by heating and rolling at elevated temperatures, supplied in bundles or coils.
• LAF Crudo (Crude Cold-Rolled Steel) Cold-rolled steel products in crude/unprocessed state, intended for further processing such as coating or annealing.
• Hojalata (Tinplate) Light-gage, low-carbon, cold-reduced steel sheet electrolytically coated with tin for corrosion resistance, used in food packaging and container applications.
• Hoja Cromada (Electrolytic Chromium-Coated Steel / ECCS) Light-gage, low-carbon, cold-reduced steel sheet with electrolytically deposited chromium and chromium oxide coating for corrosion resistance and paintability.
• Recocido (Annealed Cold-Rolled Products) Cold-rolled steel products subjected to annealing heat treatment to achieve desired mechanical properties and surface finish.
• Barras/Cabillas (Rebar and Construction Bars) Hot-rolled steel bars with circular cross-section and regularly spaced protrusions to enhance bond with concrete; used as structural reinforcement in reinforced concrete and masonry construction.
• Alambrón (Wire Rod) Hot-rolled steel product with smallest round cross-section and smooth surface, intended for wire drawing or cold deformation processes to produce wires, meshes, and fasteners.
• Tubo de Línea (Line Pipe) Hollow circular steel product without weld seam, with beveled ends, obtained from hot forming of ingots or steel bars; used for conduction of fluids (gas, petroleum, water) in the petroleum industry.
• Tubo de Revestimiento (Casing Pipe) Hollow circular steel product without weld seam, with threaded ends for coupling, obtained from hot forming; designed for oil or gas well casing in the petroleum industry.
