Steel Buyers Basics: Mill Coating Extras

Last week I discussed how Steel Mills calculate thickness and width extras.  This week we will look at Mill coating extras for Galvanized and Galvalume coated steel coil. I am going to refer again to US Steel’s published list of price extras which you can find on their website. Other mills tend to have similar extras but it is important to compare as there can be variations which can be significant depending on the product and thickness.

The US Steel’s pricing extras for Hot Dipped Galvanized/Galvannealed coil chart (HDG) begins on page 23.  The base price of HDG coil tends to be about $100 to $120 per ton higher than hot rolled coil so I will use a base price of $38.00/cwt.  (SMU latest hot rolled average is $33.25/cwt but for ease of use and example purposes we will use a $38.00/cwt base for coated products.)
