It is the process of coating iron and steel with zinc, which alloys with the surface of the base metal when immersing the metal in a bath of molten zinc at a temperature of around 4°C. When exposed to the atmosphere, the pure zinc reacts with oxygen to form zinc oxide, which further reacts with carbon dioxide to form zinc carbonate, a usually dull grey, fairly strong material that protects the steel underneath from further.

VS Galvanizing is a hot-dip galvanizing metal service company with galvanizing plants strategically located in the United States. Our galvanizing process provide fabricated steel corrosion resistance when immersed in molten zinc at a temperature of roughly 8˚F. The process is inherently simple which provides a distinct advantage over other corrosion protection methods.

The iron metallurgically reacts with the zinc to form a tightly-bonded alloy coating that protects the metal from decay and other damage. All metals revert to their ore state upon exposure to the elements.

The most common method is hot dip galvanizing, in which steel sections are submerged in a bath of molten zinc. The hot dip galvanizing process is highly versatile and articles ranging in size from nuts and bolts to long structural sections can be coated.

This range, together with the ability to bolt or weld fabrications after galvanizing, allows almost any size of structure to be hot dip galvanized. However, new technologies and creative chemistries evolve the specification and use of hot - dip galvanized steel constantly as new markets emerge.

Located in Oakland and serving the Bay Area, Northern Califona, and the Central Valley. Once dippe the steel reacts with the molten zinc to form a series of zinc-iron alloy layers, which together with the outer zinc layer, are metallurgically bonded to the steel surface.

HOT-DIP GALVANIZING Overview. This tank is called as Zinc Kettle too that contains molten zinc at about 4°C (8°F) where black steel is immersed for a determined time to get finally a coating result with a tightly-bonded alloy between iron and zinc forming itself into a long-term corrosion barrier. During the process, a metallurgically bonded coating is formed which protects the steel from harsh environments, whether they be external or internal.

The hot - dip galvanizing process consists of three steps: surface preparation, galvanizing, and inspection. Surface Preparation: For high quality hot - dip galvanizing, steel must be properly prepared prior to being immersed in a bath of molten zinc. We are the premier provider of hot dip galvanizing services in North America.

We strive to be the premier provider of galvanizing services, while honoring the golden rule with respect to our customers, employees, vendors, and the public at large. In the case of automobile bodies, where additional decorative coatings of paint will be applie a thinner form of galvanizing is applied by electrogalvanizing. The zinc coating provides both barrier and a cathodic protection to the steel. Hot Dip Galvanizing is.

Discontinuous hot-dip galvanizing (batch galvanizing ) In this process, previously manufactured steel parts (e.g. doors, metal fencing) are galvanized in one piece. Differences between continuous and discontinuous hot-dip galvanizing The main difference between the two methods is the thickness of the zinc coating.

The process, which has evolved over the years, entails dipping fabricated steel into a kettle of molten zinc. The iron in the steel reacts with the zinc to form a tightly bonded alloy coating which protects the steel from corrosion. As is known, the hot - dip galvanizing (HZ) is a reinforcement of steel with a thin layer of zinc by dipping the part into a tank filled with molten serpent.

This method exists with the only purpose - to protect the metal from destruction. This approach has become widespread due to its reliability, durability and efficiency. The process of molecular bonding between two metals is unique and simple, yet provides excellent molecular bonding and cathodic protection.

Initially the coefficient of friction between galvanized contact surfaces is low at about 0. However, when hot dip galvanizing steel, there are no such delays. Cold galvanizing, among other galvanization types, does not reach the same levels of protection as hot dip galvanization, but it can be employed as a base to make the most of the metal’s antioxidant properties.

Then, a second hand of colored finishing polish gets spread out. Galvanizing is effective in protecting steel for very long periods, thus saving energy and resources with minimal environmental impact.

Zinc scrap and hot dip galvanized steel can be easily recycled and the material can be used again for new production. As an experienced supplier to hot - dip galvanizing companies, we offer a complete range of chemicals from a single source. Our experts are there to support and advise you and to recommend the right product combination for your operational requirements.

With our strip galvanizing plants at locations in Austria, the Netherlands and Hungary, we fully cover the requirements for comprehensive corrosion protection. An ITP (Inspection Test Procedure) is incorporated at each stage of the galvanizing process including stores and dispatch.
