Coating steel with a thin layer of electrolitically deposited zinc or zincnickel to increase its corrosion resistance. It is available in a variety of coating weights depending on the protection desired. Electrogalvanizing is becoming more important today. Electrogalvanizing is a cold-coating electroplating process that, unlike the hot-dip process, does not influence the mechanical properties of the sheet steel. Electrogalvanizing provides a more uniform coating.
Hot Dipped Galvanized
Coating steel with a thin layer of zinc to increase its corrosion resistance. Most galvanizing is done on a hot-dip operation.
Galvalume steel sheet combines the best qualities of aluminum and zinc offering at least two times the corrosion resistance of galvanized. The aluminum-zinc coating provides superior corrosion resistance and heat reflectivity. It also has good bare edge protection and form qualities.
An extra tight coat of galvanizing metal (zinc) applied to a soft steel sheet, after which the sheet is passed through an oven at about 1200 degrees F. The resulting coat is dull gray without spangle especially suited for subsequent painting.
Produced by coating a soft steel with a terne metal (lead-tim alloy) coating, the surface is very ductile and acts as a lubricant for deep drawing. It also provides a surface that is readily solderable. Fuel tank applications are common due to the excellent corrosion resistance provided.
This product is designed to optimize forming, fabrication, and porcelain enameling capabilities. It is available in various grades depending on end use applications.
Steel that is coated with an aluminum or aluminum-silicon alloy coating. The coating combats the destructive effects of exposure to combinations of heat and corrosion. It is available in various grades to accommodate specific applications.
The following secondary operations can be performed on Coated Sheet Coil Steel in order to receive "Job Ready" coil or blanked product.
