According to Webster dictionary one of the definitions of “galvanized” is “the process of shocking or stimulating a muscle into action”. The definition we know is the second one listed: “to coat iron or steel with a protective layer of zinc”. The term “hot dipped galvanized” is commonly referenced although many might not know what

The production of copper is not that much different from the production of carbon steel. There are fewer ingredients required for copper but the process is practically the same. Companies who produce rolled copper buy cathodes of copper, which are basically big slabs of copper. They melt (cast) them by heating at high temperatures, add
Galvannealed is carbon steel coated with zinc/iron alloy on both sides Galvanized steel is cold-rolled carbon steel with a zinc coating on either side. The zinc provides great corrosion resistance, but it does not provide a great paint surface. It can be painted but only after the metal has been exposed to the elements for
Galvanized steel is cold-rolled carbon steel with a zinc coating on either side. Hot-dipped galvanized steel is the process of dipping fabricated steel into a kettle or vat containing molten zinc. The process is inherently simple, which provides a distinct advantage over other corrosion protection methods. While the steel is in the kettle, the iron in
Red Rust vs White Rust When most people use the term “rust”, they are referring to the “red-oxide” rust that forms when iron and oxygen react in the presence of water. This is the kind of rust that looks pretty cool on an old barn, however it is corrosive. It will eventually deteriorate the metal.

Galvanized vs Galvannealed vs Phosphatized: Coated Products Explained We sell a variety of different coated flat-rolled products. The overwhelming majority of our steel is Galvanized, followed by Galvannealed. Here is a breakdown of the differences. Galvanized steel is cold-rolled carbon steel with a zinc coating on either side. The zinc coating weight is denoted with

Steelmaking 101 With all that is happening in today’s steel market, I think it would be helpful to review the two primary ways to make steel. There are two ways to make steel—in a Blast Furnace (BOF) or in an Electric Arc Furnace (EAF). In the U.S., approximately 75% of steel is made using the
