What you save on the coating, you pay for in downtime.
We apply protective coatings to fasteners and components for oil and gas. 62 years, three generations, one plant — and every figure we publish carries its coating thickness, its test method and who ran the test.
Three coatings, and the standard for each.
The designation comes from your specification, not from a menu on our side. What we add is the measurement that proves it.
NanoGalv®
Specified under ASTM B1025-25. Salt-spray performance published by coating thickness, with the test source named. Exclusive licence in Brazil.
Zinc-nickel
12 to 16% nickel, measured by X-ray fluorescence. Class, type and grade as your order specifies — including grade 10.
Cadmium
Yellow chromate and olive drab. 1,000 h in ASTM B117, reported by an ISO/IEC 17025 accredited laboratory. Qualified by TechnipFMC for this process.
The failure mode is invisible on the part.
A zinc-nickel deposit with the wrong alloy looks exactly like one with the right alloy. Same colour, same gloss, same thickness reading. The difference shows up in the field, years later, on someone else's schedule.
That is why a thickness certificate alone proves very little, and why we measure alloy composition by X-ray fluorescence, with standards traceable to an ISO/IEC 17025 accredited laboratory. It is also why every salt-spray figure on this site is published with the coating thickness, the test method and who ran the test — including when the answer is "the licensor of the technology, not us".
The full technical site.
Process data sheets, the standards table, laboratory capability and the corrosion scale are published in Portuguese — a standard designation and a thickness table read the same in any language.
All processes
Ten coating lines with data sheets, standards and salt-spray figures.
Standards we work to
ASTM, ISO, API, AMS, NBR and the OEM specifications behind them.
