Flo-Coat Process

Allied’s steel profiles comes from an inline hot-dip galvanizing process called Flo-Coat. This one-of-a-kind technique runs welded tubing through molten zinc while still on-line.

The Flo-Coat tube process is the superior method of galvanizing steel tubing. It begins with flat strip steel, which is then cold-formed and electric-resistance or induction welded. After welding, the tube receives a triple layer of protection-zinc, conversion coating, and a clear polymer topcoat all applied in-line to assure a uniform coating. The result is a smooth, shiny end product appearance that is unmatched in terms of strength and durability.

In-line galvanized tubing exhibits greater corrosion resistance because of the synergism created between the coatings; the conversion coating passivates the zinc to slow down the white rust growth process, and the clear top-coat then “seals in” the protection.

The triple coat corrosion provided by Allied’s in-line galvanizing process has never been equaled. This triple layer protection (zinc, conversion coating, and clear organic polymer) provides a smooth, shiny product appearance that is unmatched in terms of strength and durability.
