Top 9 Iron Wire Manufacturers in Brazil

Established 1988  •  7 Specialized Factories  •  100+ Countries Served  •  BSCI Certified

Brazil’s iron wire industry runs deeper into the country’s industrial history than most buyers realize — the nail factory that eventually became Brazil’s largest steelmaker started out importing wire because no domestic producer existed yet. Today the market splits between a handful of large-scale integrated steel groups, established regional wire manufacturers serving agriculture and construction, and OEM/ODM partners supplying private-label buyers. Here’s how Brazil’s leading iron wire manufacturers compare, and where OEM sourcing fits in for brands and distributors building their own product line.

Brazilian Iron Wire Manufacturers

1. Belgo Arames

Founded: 1975  |  Base: Contagem, Minas Gerais (plus units in Osasco, Sabará, Feira de Santana, and Itaúna)

Belgo Arames grew out of a strategic partnership between ArcelorMittal and Bekaert, the world’s largest wire producer, and has operated in Brazil since the 1970s. It runs nine industrial units across the country and covers agribusiness, construction, automotive, and industrial wire segments.

2. Gerdau

Founded: 1901  |  Base: Porto Alegre, Rio Grande do Sul

Gerdau’s origin is directly tied to wire: the company began in 1901 when João Gerdau bought a struggling nail factory that, at the time, had to import its wire raw material from Europe because no domestic wire industry existed yet. Gerdau has since grown into Brazil’s largest steel producer and a major supplier of wire rod, the upstream raw material used across the country’s wire manufacturing sector.

3. Telmetal

Founded: Over 50 years in the metalworking market  |  Base: São Paulo, SP

Telmetal manufactures galvanized wire and wire mesh for fencing and construction applications, with a production process built around metal coating for corrosion resistance and durability.

4. Morlan

Base: Brazil, national distribution

Morlan was the first manufacturer in Brazil to adopt the alternating-twist barbed wire technique, and its products are made to the ABNT NBR 6317 national standard. Its Nelore barbed wire line is one of the best-selling barbed wire products in the country.

5. Wireplast

Base: Brazil

Wireplast produces its own galvanized wire in-house and specializes in galvanized and nylon-coated wire used for spiral binding, wire-o double-loop binding, and paper clips and fasteners — a narrower niche than general construction or agricultural wire.

6. New-fix

Base: Brazil

New-fix manufactures fastening products including wire, screws, and nails, and positions itself as working toward becoming one of Brazil’s largest fastener manufacturers, with quality control applied across its product range.

7. Central Mesh

Base: Brazil

Central Mesh supplies galvanized wire across a full range of BWG (Birmingham Wire Gauge) diameters, from heavier construction gauges down to fine wire, with products kept in ready stock for agricultural, construction, and manufacturing applications.

8. Trade Fence (Casa da Tela)

Founded: 15+ years  |  Base: São Paulo, SP

Trade Fence, operating as Casa da Tela, supplies galvanized wire, fencing, and mesh across São Paulo state and holds PEQ (Quality Excellence Program) certification.

9. Yongwei

Founded: 1988  |  Type: OEM/ODM manufacturer  |  Reach: 100+ countries  |  Certification: BSCI-certified, EU market access

Yongwei is a China-based OEM/ODM iron wire manufacturer operating seven specialized factories, supplying customers in more than 100 countries. Unlike the domestic manufacturers above, it does not sell under its own retail brand in Brazil — it produces to the buyer’s specification, covering galvanized wire, PVC-coated wire, wire mesh, and barbed wire, with BSCI-certified, audited production and tolerance control suited to bulk private-label and distributor orders.

Why Brazil’s Wire Industry Started With an Import Problem

It’s worth understanding where Brazil’s wire industry actually came from. When Gerdau’s founders acquired their nail factory in 1901, the raw wire had to be imported from Europe every few weeks — there was no domestic supply chain to draw on. That gap is what eventually pushed Brazilian steel groups to build their own wire rod and wire production from the ground up. More than a century later, a version of the same gap still exists for many buyers: domestic manufacturers cover standard construction and agricultural wire well, but a brand building a custom product line — specific coatings, gauges, or packaging — often runs into the same limitation Gerdau’s founders did: the domestic options don’t quite match the spec they need.

Sourcing Custom Iron Wire Through an OEM Partner

If your buyers need standard galvanized or barbed wire off the shelf, the domestic manufacturers above cover most of that ground directly. If you’re a distributor or brand owner who wants a specific coating, tensile strength, packaging, or private-label branding, an OEM/ODM partner works from your spec rather than a fixed catalog. This is a different calculation from “domestic vs. imported”: it’s about who controls the product specification and the margin, and whether a domestic factory’s standard range can actually match what you’re trying to sell.

FAQ

What standard applies to barbed wire manufactured in Brazil?
Barbed wire sold in Brazil is generally manufactured to the ABNT NBR 6317 standard set by the Associação Brasileira de Normas Técnicas, Brazil’s national standards body. Buyers sourcing from any manufacturer, domestic or OEM, should confirm the product is built to this specification if it’s intended for the Brazilian market.

Is it better to buy iron wire from a Brazilian manufacturer or import from an OEM partner?
It depends on the product. For standard galvanized or barbed wire at retail or agricultural scale, established domestic manufacturers are often the more direct route. For custom specifications, private-label branding, or large bulk orders at a lower per-unit cost, an OEM/ODM partner is typically better suited to that kind of order.

What’s the difference between wire rod and finished iron wire?
Wire rod is the hot-rolled coiled steel that serves as the raw material for wire production. Large steel groups such as Gerdau produce wire rod at scale, while wire manufacturers draw it down further and finish it into galvanized, coated, or barbed wire products for end use.

Conclusion

Brazil’s iron wire industry ranges from century-old steel groups that trace their roots to the country’s first wire shortage, to regional manufacturers serving agriculture and construction, to OEM/ODM partners built for custom and private-label orders. If you’re sourcing standard wire products, the domestic manufacturers above are worth comparing directly. If you’re building a custom or private-label wire product line, an OEM/ODM partner is generally the more direct path to a product built to your own specification.
