Zinc-Tech™ In-Line Galvanizing Process

Fully galvanized exterior

360 Degrees of Protection

Zinc-Tech™ provides full protection over the circumference of the tube exterior, including the weld seam through our unmatched process using molten zinc. Say goodbye to weld line rust and failure of your steel product which affects your brand name, quality and reputation.

Zinc-Tech™ in-line galvanizing process is designed and engineered to perfection and helps you control the zinc coating on your products like pipes, tubes, scaffoldings, electrical conduits, fence tube, agricultural product tubes and greenhouse structure tubes. With the Zinc-Tech™ in-line galvanizing process you are able to control zinc coating weight by 45 g/m2 to over 250 g/m2 without affecting the quality and performance of the end product and support superior corrosion protection which would be difficult to attain with hot dip galvanizing.

Zinc-Tech™ in-line galvanizing process facilitates uniform coating over the entire surface of the product with molten zinc after surface preparation. No matter the product length, as long as it can be manufactured on the line, Zinc-Tech™ can perform the galvanizing process with ease and perfection. Galvanized steel products are often looked upon to share maximum corrosion protection, and the same being administered with continuous galvanizing method saves time and provides superior quality products.

Thick, free zinc layer

Get Top Corrosion Performance

Zinc-Tech™ in-line galvanizing process applies a fully fused zinc coating to the exterior surface after the process of seam welding. This is beneficial in that the total circumference of the tube is coated with zinc including the section of weld seam which could be compromised if the galvanized coating would have been performed at pre welding stage.  Zinc-Tech™ provides an equal amount of protection over the entire surface of the tube including the weld seam. Unlike products manufactured using pre-galvanized strip materials with a metallized seam, the weld seam has the same level of protection as the body of the tube or pipe. It is widely accepted that metallization of the weld seam will fail far more rapidly than the pre - galvanized strip material due to being affected with the welding process.

The Zinc-Tech™ process applies the highest percentage of "Free Zinc" weight as a percentage of overall coating weight. Fundamentally stated, other galvanizing processes like hot dip galvanizing have higher percentage of zinc - iron alloy layers. Our process by nature of its design applies a very thick layer of ductile pure zinc coating absent of iron. Up to three times greater than that of alternative galvanizing methods. The result is a galvanized coating that due to its composition will resist corrosion at a much higher rate.

Viewing the corresponding micrograph you will note the compressed zinc-iron alloy layers. Only the base layer which promotes adhesion is well defined. the total % of "free zinc" is approximately 80% of the total coating thickness.

The respective micrographs demonstrates the significantly greater concentration of free or pure zinc that is characteristic of Zinc-Tech™ in-line galvanizing process. This is the fundamental reason for the exceptional corrosion performance exhibited by the products manufactured utilizing our technology.
