What Resinex does

Resinex (legal name Protendidos Resinex Ltda) is a privately held Brazilian specialty industrial manufacturer founded in 1993 and headquartered in Criciúma, Santa Catarina. The company designs and produces high mechanical resistance prestressing systems, with its core product being monobar tie rods (tirantes) featuring a proprietary continuous thread design, available in models RT-00 through RT-10 and RX variants with working loads ranging from 6 to 120tf. The product line is completed by a full accessory ecosystem including anchor nuts, plates, coupling sleeves with a proprietary STOP system, angular compensation rings, spacers, sleeve valves, metal sheaths, anchor bolts, and resin cartridges. All products are manufactured from 100% nationally sourced raw materials developed exclusively for Resinex, comply with ABNT NBR-5629:2018, and are quality-tested at Falcão Bauer laboratories; anti-corrosion treatments meet Petrobrás N-1761 and Usiminas NCU-0201 standards.

The company sells directly to engineering firms, construction contractors, and government infrastructure project developers on a project-by-project quotation basis, with no intermediaries. Its installed base includes marquee Brazilian public infrastructure references — Maracanã and Fonte Nova stadiums, Metrô de Salvador, Imigrantes Highway, Rota do Sol Highway, Régis Bittencourt Highway, Eurico Salles Airport, the Irapé and Capanda hydroelectric plants (Capanda in Angola), the PCH Castro small hydro plant, and the Bom Jardim da Serra wind farm — demonstrating penetration across sports, urban transit, road, airport, hydroelectric, and wind power verticals. Resinex states its products are present in all 27 Brazilian states.

Revenue is generated through one-time industrial sales of tie rods and accessories supplied in custom project-specific lengths to eliminate waste, with an additional professional services layer for factory-applied epoxy anti-corrosion protection. Pricing is opaque and quote-based, the company is privately held with no disclosed investors or parent entity, and there is no publicly available revenue, headcount, or financial disclosure. The 2014 inauguration of a 3,500 m² headquarters marked the most significant physical expansion on record, and the Angola delivery evidences latent cross-border execution capability.
