Alufer

What Alufer does

Alufer S.A. is a privately held Brazilian structural steel construction company founded in 1962 by Siro Palenga in Itu, São Paulo, with over 60 years of continuous operation. The company designs, fabricates, and installs custom steel structures for industrial plants and civil construction, delivering end-to-end services that span structural calculation, basic and detailed engineering, CNC-automated manufacturing, surface treatment and painting, and on-site field assembly. Its product portfolio covers process buildings, pipe racks, industrial buildings, multi-story commercial buildings, aircraft hangars, stadiums, bridges, viaducts, platforms, warehouses, towers, transmission towers, and heliports.

Operations are anchored by a 60,000 m² integrated manufacturing facility in Itu, São Paulo (less than 100 km from the state capital), equipped with automated CNC machining lines and advanced surface treatment and painting equipment. A separate Technical-Commercial Division in São Paulo handles sales and client relations for the company, which is qualified under an Integrated Management System certified to ISO 9001, ISO 14001, and ISO 45001.

Alufer sells almost exclusively to enterprise and institutional buyers across Brazil on a project-based, quote-driven basis, with documented customers spanning the steel, mining, petrochemical, automotive, oil and gas, energy, paper and pulp, aluminum, tire manufacturing, media, sports, education, and healthcare sectors — including Petrobras, CSN, Ford do Brasil, Renault, Embraer, Goodyear do Brasil, Suzano, Klabin, Votorantim Metais, Veracel, Alunorte, Hospital Albert Einstein, and Arena Corinthians. Pricing is not publicly disclosed, project sizes range from hundreds to thousands of tons of steel, and revenue is generated principally through one-off fabrication and assembly contracts supplemented by technical advisory services to architecture and engineering firms on steel-specific project design.

Direct peers

• Açotubo (Grupo Açotubo): Brazilian manufacturer and fabricator of steel structures, tubes, and related products serving industrial construction markets. Overlaps with Alufer in steel structure fabrication for industrial and commercial applications across Brazil.
• Codeme Estruturas Metálicas: Brazilian steel structure fabricator with a similar end-to-end model covering engineering, fabrication, and assembly for industrial and commercial construction. Competes with Alufer for industrial building contracts in the Brazilian market.
• Cimaf Estruturas Metálicas: Brazilian steel structure manufacturer focused on industrial buildings, sheds, and process structures. Direct competitor to Alufer in the Brazilian mid-to-large scale industrial steel structure market.
• Brafer Estruturas Metálicas: One of the largest Brazilian structural steel fabricators, serving heavy industrial sectors including oil & gas, mining, energy, and paper & pulp. Direct competitor to Alufer on multi-thousand-ton process building and pipe rack projects for Petrobras, Vale, and similar customers.
• Metalflex Estruturas Metálicas: Brazilian structural steel fabricator offering design, fabrication, and assembly services for industrial and commercial projects. Comparable in scope and target market to Alufer's core structural steel business.

Broad incumbents

• Voestalpine AG (Steel Division): Global steel and steel-processing group with significant structural steel fabrication capabilities serving industrial, construction, and infrastructure markets. Comparable in product range and end-market exposure, though at much larger scale and with integrated steelmaking.
• BlueScope Steel Limited: Australian-listed global steel manufacturer with a Buildings segment producing pre-engineered steel buildings and structural solutions for industrial and commercial markets. Comparable in product mix and end-market orientation to Alufer, though far larger and globally diversified.
• NCI Building Systems (Cornerstone Building Brands): US-based manufacturer of metal buildings, components, and engineered steel structures for commercial and industrial construction. Comparable product portfolio (pre-engineered steel buildings, components), though more standardized and lower-tonnage than Alufer's heavy industrial focus.
• Severfield plc: UK-listed structural steel fabricator serving commercial construction, industrial, and infrastructure projects. Useful international benchmark for Alufer on scale, vertical integration, and project execution economics, though operating in a different geography.

Regional players

• Zamil Steel Buildings Company: Saudi Arabia-based global steel structure fabricator serving industrial, commercial, and infrastructure projects across the Middle East, Africa, and Asia. Comparable in vertical integration and project-based model, though operating in a different geographic region than Alufer's Brazil-only footprint.
