Powder Coating Hot-Dip Galvanized Steel

October 1, 2011

Powder coatings on hot-dip galvanized steel provide an excellent corrosion resistant coating. The selection of this duplex system has two major attractions; the duplex system provides a high-grade architectural finish that does n... Read More...

Painting zinc rich

September 1, 2011

Zinc-rich paints contain 65-94% metallic zinc in the film of the paint after it dries. The paints are usually applied by brushing or spraying onto steel that has been cleaned by sandblasting. While white metal blasting (NACENo. 1... Read More...

Mechanical Plating

September 1, 2011

Production Process Small iron and steel parts may be coated by drum tumbling with a mixture of proprietary promoter chemicals, zinc powder and glass beads. After cleaning, the parts, which are usually limited in size to about 8-... Read More...

Metallizing

September 1, 2011

Production Process The sprayed zinc coating is rough and slightly porous, with a specific gravity of 6.4, compared to zinc metal at 7.1. Zinc corrosion products tend to fill the pores as the zinc corrodes in the atmosphere. The ... Read More...

Zinc Plating

September 1, 2011

Production Process: Zinc plating is identical to electrogalvanizing in principle in that both are electrodeposition processes. Zinc plating is used for coatings deposited on small parts such as fasteners, crank handles, springs,... Read More...

Electrogalvanizing Electrogalvanized

August 27, 2011

Electrogalvanized coatings are applied to steel sheet and strip by electro-deposition. Electrogalvanizing is a continuous operation where the steel sheet is fed through suitable entry equipment, followed by a series of washes and... Read More...

In-line Continuous Sheet Galvanizing

August 27, 2011

The continuous sheet galvanizing process is also a hot-dip process. Steel sheet, strip or wire is cleaned, pickled, and de-oxidized on a processing line 500 feet in length, running at speeds of over 300 feet per minute. In the co... Read More...

High Temperature Galvanizing

August 27, 2011

High temperature galvanizing is very similar to batch hot-dip galvanizing at a conventional temperature (830ºF). The steel is run through a batch process beginning with multiple chemical pretreatment tanks used to clean residues... Read More...

Zinc Coating

August 27, 2011

Zinc metal has a number of characteristics that make it well suited for use as a coating for protecting iron and steel products from corrosion. Its excellent corrosion resistance in most environments accounts for its successful u... Read More...

General Corrosion Corrosion and Galvanic Compatibility

July 16, 2011

General corrosion involving water and steel generally results from chemical action where the steel surface oxidizes, forming iron oxide (rust). Many of the systems and components in the plant are made from iron. Some standard me... Read More...

Galvanic corrosion

July 16, 2011

Galvanic corrosion occurs when two dissimilar metals with different potentials are placed in electrical contact in an electrolyte. It may also take place with one metal with heterogeneities (dissimilarities) (for example, impurit... Read More...

Galvanising Galvanized

July 6, 2011

Galvanising is a method of protecting a steel surface from corrosion by providing a surface coating of  Zinc. Galvanised coatings corrode preferentially to steel, providing sacrificial or cathodic protection to small areas of ... Read More...

Painting Process
