Join the next generation of galvanizing excellence.
With Zinc-Tech™ In-Line Galvanizing, your products receive full exterior coverage, including over the weld seam—ensuring consistent 360-degree protection against corrosion. Our advanced zinc coating process eliminates the common issue of weld line rust, safeguarding your brand reputation, product performance, and customer trust.
Unlike traditional hot-dip galvanizing, Zinc-Tech™ allows precise zinc coating control from 50 to over 250 g/m², ensuring superior corrosion resistance across a wide range of steel tubulars.
Whether you're manufacturing short lengths or continuous profiles, Zinc-Tech™ applies a uniform, high-quality zinc coating that adheres seamlessly to the entire surface—ensuring performance, durability, and compliance with international standards.
Unlike traditional hot-dip galvanizing, which involves batch processing and manual handling, the Zinc-Tech™ In-Line Galvanizing System uses a continuous, integrated process that delivers a high-luster, smooth finish directly on the production line.
This advanced galvanizing technology eliminates the limitations of conventional hot-dip methods, where products must be manufactured, stored, and then processed through multiple stages—pickling, rinsing, drying, fluxing, zinc immersion, quenching, and bundling. These steps not only require extensive space and labor but also increase the risk of handling damage and inconsistent finish quality.
With Zinc-Tech™, everything is integrated into the tube mill line:
Inline surface preparation and zinc coating
No additional work in progress inventory or off-line transfers
Consistent zinc coating thickness control in real time
The galvanized steel pipe production line with Zinc-Tech™ system can be operated efficiently with as few as 2–3 personnel
Whether you're producing structural tubes, conduits, or scaffoldings, Zinc-Tech™ ensures your product exits the line with a premium, brilliant finish—ready for shipment or installation.
Products galvanized using Zinc-Tech™ not only meet performance standards but also exceed visual expectations—making them more appealing in competitive markets and enhancing your brand’s value.
With Zinc-Tech™ In-Line Galvanizing, your tubes and pipes receive a fully fused, high-purity zinc coating across the entire outer surface—including the critical weld seam, post-welding. Unlike pre-galvanized strip material where the weld seam is often the weak link, Zinc-Tech™ ensures uniform protection over the full circumference of the product, drastically reducing the risk of corrosion failures.
Pre-galvanized strips, when welded, expose the seam to heat-affected zones where metallization often fails over time. Zinc-Tech™ avoids this by applying a thick, ductile pure zinc coating after welding, offering the same level of corrosion resistance at the seam as the rest of the tube—a major advantage over conventional methods.
Unlike traditional hot-dip galvanizing, which forms a significant portion of brittle zinc-iron alloy layers, Zinc-Tech™ delivers a coating that is:
Composed of up to 80% pure, free zinc
Up to 3x thicker in free zinc than alternative processes
More ductile, resilient, and better at resisting corrosion over time
Our process promotes a dense, well-bonded adhesion layer, while maximizing the upper protective layer with pure zinc, which actively guards against environmental degradation.
Unlike conventional Hot-Dip Galvanizing, which may reduce material integrity due to prolonged heat exposure, Zinc-Tech™ In-Line Galvanizing rapidly heats and cools the tube during the zinc application process—enhancing both tensile and yield strength.
Zinc-Tech™ galvanized tubes consistently outperform hot-dip galvanized products in mechanical strength tests. The process supports improved grain structure and surface integrity, making the finished product:
Stronger and more impact-resistant
Better suited for load-bearing applications
Ideal for thinner wall designs—without sacrificing performance
If using low-carbon steel, you can expect significant gains in strength post-galvanizing. When higher-grade raw materials are used, proportional strength increases are also maintained—ensuring reliable performance in demanding applications.
Your customers get more than just corrosion resistance—they get superior strength, which opens up new possibilities for:
For electrical conduit products, nothing matches the quality and efficiency of the Zinc-Tech™ in-line galvanizing process.
For farming and agriculture purposes, our triple-coated, non-porous exterior prevents bacteria from penetrating the surface of products.
For fencing, our superior zinc coating composition, surface treatment, and available top coats provide the ultimate protection against white rust.
In greenhouse structures, Zinc-Tech™ allows for the use of lighter wall material, resulting in cost savings for your customers.
Zinc-Tech™ allows you to produce products that accurately match material consumption to customer specification.
The staff at Superior Technologies trained our staff on running the new technology and in a very short time our staff was running the line smoothly and we were able to produce a wide range of good quality products which were later certified by UL.
From the beginning through to the aftermarket support, Superior Technologies has been very supportive and responsive to our questions and needs. They work more as partners than suppliers.
Superior Technologies have been a pleasure to work with and have a vast amount of knowledge and experience relating to the tube industry. Anytime there was a question or feedback requested, Mr. Chifo or his staff were available to address any items.
With the Zinc-Tech process we are able to export quality pipes and compete with the US products.
Look at the wide range of finished products that are currently being produced more efficiently, at a lower cost and with a consistently higher quality than any other galvanizing process. Any and all of these products can be produced on a single installation.
