Top 8 Wire Manufacturers in Mexico

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

Mexico’s wire industry is the most internationally integrated in Latin America, and it isn’t close. Deacero, the country’s largest wire producer, opened a trade office in Washington, D.C. in 2021 and runs the largest nail factory in the United States. Ternium Mexico traces back to Hylsa, a company whose ownership group once co-owned Venezuela’s SIDOR before its 2008 nationalization. Aceros Camesa runs plants in Mexico City, Texas, and Lima, Peru. This isn’t a domestic market that happens to export — it’s a network built around the US border and USMCA from the ground up. Here’s how Mexico’s leading wire manufacturers compare, and where OEM sourcing fits into that picture.

At a Glance

Mexican Wire Manufacturers

1. Deacero

Founded: 1952  |  Base: Monterrey, Nuevo León

Deacero began in a small Monterrey warehouse sorting rejected US wire into fencing, integrated its own steelmaking in 1981, and has grown into one of the world’s largest wire producers, family-owned, with over 8,000 employees, 21 recycling centers, 3 steel mills, and 15 wire facilities across 20+ countries. Its US operations include the largest nail manufacturer in the United States, based in Poplar Bluff, Missouri, and it opened a trade and corporate affairs office in Washington, D.C. in 2021 — the first Mexican company to do so.

2. Ternium Mexico

Founded: predecessor Hylsa dates to 1943; part of Ternium since the Techint Group’s 2005–2007 consolidation  |  Base: Monterrey and Puebla

Ternium Mexico traces back to Hylsa/Hylsamex, whose wire and rod division was long established before the Techint Group folded it into Ternium alongside Argentina’s Siderar. Notably, Hylsamex’s ownership group once held a stake in Venezuela’s SIDOR steel plant through the 1990s Amazonia Consortium privatization, before SIDOR was nationalized by the Venezuelan government in 2008. Ternium’s Puebla plant today produces rebar, wire rod, and round bar for construction, industrial, and automotive customers.

3. Grupo Simec (ICH)

Base: Guadalajara, Jalisco, and Mexicali, Baja California  |  History: ICH acquired 82.5% of Grupo Simec in 2001

Grupo Simec manufactures rebar, wire rod, wire mesh, and structural steel products, and expanded internationally with a Brazilian facility in 2011 and acquisitions of former ArcelorMittal plants in Brazil in 2018, alongside operations in the United States and Canada.

4. AHMSA

Founded: 1942  |  Base: Monclova, Coahuila

Altos Hornos de México is one of the country’s original large-scale integrated steel producers, with crude steel capacity exceeding 5.5 million tonnes a year using Coahuila and Chihuahua coal and iron ore.

5. Aceros Camesa

Founded: 1953, as Cables Mexicanos S.A.  |  Base: Mexico City area, with plants in Rosenberg, Texas, and Lima, Peru

Camesa was founded by Mexican and American investors to sell high-carbon steel wire rope, became Aceros Camesa in the 1960s, and has held ISO 9001 certification since 1993. It manufactures high-carbon wire and cable for mining, fishing, oil, and electrical transmission industries across four production plants spanning three countries.

6. Mallalux

Founded: 1975  |  Base: Mexico, national distribution

Mallalux manufactures galvanized wire fencing products, including hot-dip galvanized G60 welded mesh and security concertina, distributed and installed across the country.

7. Mallacero / MallAcerco

Base: Monterrey, Nuevo León, and Coahuila  |  History: over 30 years

Mallacero (also operating as MallAcerco) supplies chain-link mesh, hexagonal mesh, welded panel, ornamental fencing, and related wire products for agricultural, industrial, and residential use across northern Mexico.

8. 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. It produces to the buyer’s specification, covering galvanized wire, PVC-coated wire, wire mesh, and barbed wire, with BSCI-certified, audited production suited to bulk private-label and distributor orders.

Why Mexico’s Wire Industry Looks North, Not Just Inward

What sets Mexico apart from most other wire markets in the region is how deliberately its largest producers have built around the US relationship rather than just exporting to it. Deacero didn’t just start selling into the US — it bought and now operates the country’s largest nail factory, and its CEO has publicly lobbied Washington on Section 232 tariff policy on behalf of both companies’ interests. Camesa runs a production plant inside Texas itself. Ternium’s lineage runs through a consortium that once controlled Venezuela’s SIDOR, tying Mexico’s steel history to a very different outcome elsewhere in Latin America. None of this changes what a Mexican distributor or brand owner actually needs day to day — reliable wire product at a workable cost — but it does mean the market here reacts more directly to US trade policy and tariff decisions than most of its neighbors.

Sourcing Wire Through an OEM Partner

If your buyers need standard galvanized or mesh wire, Mexico’s established manufacturers cover that ground directly, often at a scale few other Latin American markets can match. If you’re a distributor or brand owner who needs a specific coating, gauge, or private-label packaging outside the pricing and trade dynamics tied to USMCA steel policy, an OEM/ODM partner works from your exact spec rather than a fixed catalog, offering a sourcing option less exposed to North American tariff swings.

FAQ

Does US steel and wire tariff policy affect the Mexican wire market?
Yes, directly. Mexico’s largest wire producers, including Deacero, have significant US manufacturing operations and have publicly engaged with US Section 232 steel tariff policy, since pricing and trade flows for Mexican wire and steel are closely tied to US trade decisions under USMCA.

What standard applies to wire products manufactured in Mexico?
Mexican wire manufacturers typically certify products against Normas Oficiales Mexicanas (NOM) or Normas Mexicanas (NMX) for domestic sale, and against ASTM specifications for products destined for the US market under USMCA. Buyers should confirm which standard a given supplier’s product is certified against.

Is it better to source wire from a Mexican manufacturer or import from an OEM partner?
It depends on the product and where it will be sold. For standard wire sold domestically or exported to the US, Mexico’s established manufacturers are often the more direct route given the country’s USMCA trade position. For custom specifications, private-label branding, or markets outside North American trade dynamics, an OEM/ODM partner is often more practical.

Conclusion

Mexico’s wire industry is built less like a domestic market and more like a cross-border production network, with its largest players running factories, offices, and trade advocacy directly inside the United States. If you’re sourcing standard wire products, the manufacturers above are worth comparing directly. If you’re building a custom or private-label wire product line, particularly for markets outside the USMCA trade framework, an OEM/ODM partner is generally the more direct path to a product built to your own specification.
