Sidersa

What Sidersa does

Sidersa is an Argentine B2B steel manufacturer and wholesale distributor headquartered in Rosario, operating two industrial plants (San Nicolás de los Arroyos in Buenos Aires province and Justo Daract in San Luis province) plus commercial offices in Rosario and Buenos Aires. The company produces a comprehensive portfolio of flat and formed steel products—including sheets, strips and blanks, galvanized/cincalum/prepainted roofing sheets, welded tubes, cold-formed C/U/Z profiles, heavy hot-rolled plates, and rolled profiles (U, I, H, W, angles, flats, bars)—compliant with IRAM and ASTM standards and serving over 2,000 wholesale clients across construction, infrastructure, agriculture, mining, oil and gas, energy, and industrial manufacturing. Current annual production capacity is 250,000 tonnes, supported by 650+ direct employees, an in-house extranet platform for 24/7 client order management, and an ESG infrastructure that includes two solar parks (notably Ullum IV at 24 MW) and IRAM carbon footprint certification.

The company makes money through wholesale one-time sales of steel products to enterprise customers, with no retail or individual consumer channel, supplemented by revenue from surplus solar energy generation that exceeds its own consumption by approximately 7x. Its go-to-market is relationship-driven: a direct sales force, the online extranet platform, and participation in trade events such as Expoagro for agricultural clients. Sidersa's near-term strategic trajectory is dominated by Proyecto Sidersa+, a $305M greenfield steel mill under construction in San Nicolás de los Arroyos—the first industrial project approved under Argentina's RIGI incentive regime—deploying Italy's Danieli MIDA continuous-process minimill technology (the only such facility in the Southern Hemisphere). When the plant commissions in 2028, it will add 360,000 tonnes/year of long steel capacity (rebar and wire rod), more than doubling total output, enabling entry into mining, energy and oil-and-gas supply chains, and capturing a 77% reduction in CO2 versus traditional blast furnace steelmaking with 99.5% scrap-input capability.

Core offering

Sidersa is a vertically integrated Argentine steel manufacturer and wholesaler that produces and distributes a comprehensive range of flat and long steel products, including steel sheets, strips, blanks, roofing and cladding sheets, welded tubes, cold-formed profiles (C, U, Z), heavy hot-rolled plates, hot-rolled structural profiles (U, I, H, W), and angles/flats/bars. The company sells exclusively on a wholesale B2B basis to construction companies, metalworking shops, infrastructure developers, and industrial manufacturers across Argentina, with planned expansion into rebar and wire rod production via the Sidersa+ minimill.

Product overview

Sidersa is an Argentine steel company offering a comprehensive portfolio of steel products, operating as both a manufacturer and commercial distributor. The product range includes: (1) flat steel products – steel sheets, strips, blanks (hojas, flejes y blanks), and heavy rolled plates (chapa laminada gruesa); (2) roofing and cladding solutions – galvanized, cincalum, and prepainted sheets (chapa para techos y cerramientos); (3) formed products – welded steel tubes (tubos de acero con costura) and cold-formed profiles (perfiles conformados) in C, U and Z shapes; (4) long steel products – hot-rolled profiles including U, I, H, W series, angle profiles, flats, and round/square bars. The company also operates an online client Extranet platform for order management. With its Proyecto Sidersa+ expansion, the company is constructing a new steel mill in San Nicolás using Danieli technology to enter long steel production (varilla and alambrón) for construction, mining, energy, and infrastructure sectors, doubling its current capacity.

Direct peers

• Ternium (Argentina operations): Major Argentine flat and long steel producer (subsidiary of Techint's Tenaris/Siderca ecosystem). Directly competes with Sidersa across construction, infrastructure, and industrial steel customers in the same Argentine market.
• Acindar (ArcelorMittal): Argentina's largest long steel producer (rebar, wire rod, profiles) and a subsidiary of ArcelorMittal. Head-to-head competitor on the long-product lines that Sidersa+ is being built to enter, serving the same construction and industrial clients.
• Tenaris: Argentine-founded steel pipe and tube manufacturer (Techint group). Comparable in steel manufacturing heritage and Argentine footprint, with overlap in tubular products and a similar focus on serving oil & gas customers that Sidersa is targeting.
• GMS (Grupo Metalúrgico San Martín): Argentine metalworking and steel products manufacturer serving similar construction and industrial customers. Domestic peer overlapping in formed profiles, tubes, and structural components for the Argentine market.

Broad incumbents

• Gerdau: Latin America's largest long steel producer with Brazilian roots and Argentine operations (Gerdau Corsa). Comparable in product mix (rebar, structural profiles) and serves overlapping construction/infrastructure customers across the region.
• Usinas Siderúrgicas de Minas Gerais (Usiminas): Brazilian integrated flat steel producer with potential to serve Argentine markets. Comparable as a regional steel incumbent whose export flows can affect Argentine steel pricing and competitive dynamics.
• Companhia Siderúrgica Nacional (CSN): Large Brazilian integrated steelmaker with flat and long product capabilities. Regional incumbent whose export posture and capacity utilization decisions directly influence Argentine steel pricing and competitive intensity.
• Ternium México / Grupo Imsa: Latin American flat and coated steel operations within the broader Ternium/Techint group. Comparable in process technology and downstream product mix, though primarily Mexico-focused rather than Argentine.

Regional players

• Villacero: Mexican steel producer with long-product and tubular offerings serving construction and industrial markets. Comparable in product mix and scale, but operates in a different geography (Mexico/USMCA) without direct Argentine market overlap.

Others

• Danieli: Italian steel plant equipment supplier providing the MIDA minimill technology to Sidersa+. An enabling ecosystem partner rather than a competitor — but critical to Sidersa+'s capital plan, commissioning timeline, and proprietary process know-how.
