CSI Increases Zinc Coating Extras

Written by Michael Cowden

California Steel Industries (CS) will increase its zinc coating extras effective July 1.

“Due to changing zinc costs, our galvanized coating extras have been revised,” the company said in a letter to customers on Friday, May 14.


The West Coast slab re-roller last increased coating extras in early December.

Zinc prices have since risen.

Zinc prices averaged $2,829.01 per metric ton in April 2021, according to data from the International Monterary Fund compiled by the Federal Reserve Bank of St. Louis.

The price in April, the last full month for which data are available, was up 1.8% from $2,779.85 per metric ton in December 2020, when CSI last increased coating extras.

Steel is run through a bath of molten zinc in a process known as hot-dipped galvanizing. The resulting zinc coating helps prevent rust.
