Eventually, the zinc will be corroded, although how long this takes depends on the thickness of the coating and the environment. Galvanized steel has a much shorter lifespan when it’s regularly exposed to rain or seawater.

Various American Society for Testing and Materials (ASTM) specifications provide guidelines and continuity for the thickness of galvanized metals. Galvanization of nails and screws is the most common method of preventing the unsightly staining seen on many types of house siding.

What Are the Different Uses of Galvanized Iron?

Galvanized iron is iron ore that has been refined, molded and coated with zinc plating. The zinc provides the galvanization, as zinc resists corrosion typical of ungalvanized wrought or cast iron. Galvanized iron is manufactured and used for wide variety of purposes but its primary use is for sheet metal roofing and other building materials, such as metal framing studs, metal roof shingles and fencing. Other uses include wire mesh, pipes, roof ornaments and other decorative exterior architectural products, gutters, flashing, metal buckets and connectors, such as screws and nails. The material resists rust and is therefore a very…

Critical role of galvanized steel in the mining industry

The mining industry requires a significant investment in infrastructure to be as efficient and as productive as possible. This is where galvanized steel plays a critical role, reports Simon Norton, Manager, Africa Desk of the International Zinc Association.

Essential infrastructure in the mining industry ranges from steel shaft structures (buntons, station steelwork, headgear) to stope structures (roof supports, pipe hangers), haulway structures (ore transfer stations, electrical stubbies) as well as surface structures (plant buildings, tank supports, pipe gantries, conveyor belts, stacks, stockpile structures, stairways, railings).

Maintenance of structural components can often be difficult because of the environment of exposure (including those…

Hot dip galvanizing versus zinc-rich paint

Engineering and technical staff often get confused over the various terms bandied about in South African industry such as ‘galvanized’ or ‘cold galvanizing’ or ‘zinc-rich paints’. So, what’s the difference?

It is metallic zinc in hot dip galvanizing that affords cathodic protection and barrier protection to galvanized steel. The extent of protection offered is directly proportional to the zinc coating thickness.

This is not so for zinc-rich paint, which consists of fine zinc powder dispersed in a dry film of paint resins. A further factor to be considered is the environment to which these coatings would be exposed. Paint coatings are…

The credit for the invention of galvanization goes to Stanislas Sores.
Galvanized steel can live up to almost 170 years! Free from corrosion
Galvanized steel is waterproof and prevents water damage well.

Like any other metal in the universe, cars are susceptible to corrosion or rusting. Corrosion refers to the metal surface’s oxidizing process that leads to its deterioration and eventual disintegration. It is extremely important to prevent car parts from getting damaged due to corrosion. One of the best ways to prevent corrosion is by galvanization. Let us look at what galvanization is and find out the advantages of galvanizing the…

  • Leave a comment

Pressure vessels are the names given to closed containers that house gases or liquids at a significantly different pressure to ambient pressure. Given that safety and reliability are two key factors in the utility of pressure vessels, their production process is tightly controlled and the products are often tested for quality.

A range of materials can be used to fabricate pressure vessels, including pressure vessel steel. Pressure vessel steel, as the name suggests, is specifically designed and engineered to meet the stringent regulations regarding the manufacture of pressure vessels.

Galvanized Steel

What Does Galvanized Steel Mean?
Galvanized steel is a type of steel that has been galvanized by the application of a zinc coating throughout its body so that it can be protected from corroding or rusting. Galvanized steel has a longer life and durability compared to non-galvanized steel. The application process of zinc on a steel structure is called “galvanization.” This process was first invented and developed in France and England in 1837, in which a sheet of steel was dipped in a molten zinc bath (a method called “hot…

Using continuously galvanized steel for light steel frame building

Light steel frame building (LSFB) is not the same as prefabricated or ‘kit’ buildings, as it is rather a building method. Another term is ‘off-site’ construction, due to the fact that a lot of the manufacturing takes place in factories, whereafter the components are transported and assembled on-site. LSFB consists of structured wall panels, trusses and floor joists that are assembled using cold-formed steel sections, which in turn are made from thin-gauge high-strength continuously galvanized steel sheet.

Hot-dip galvanized substrate is produced on continuous zinc coating lines from either cold-rolled (thickness range 0.27 mm to < 2.0 mm) or hot-rolled...
