HDGL #1 and #3 Components

AM/NS Calvert has the ability to produce 1.5m tonnes/year of Coated products (under current configuration), including Galvanized (GI), Galvannealed (GA), and Aluminized (AL) as well as 700,000 tonnes/year of fully-finished (continuously annealed) Cold Rolled. HDGLs #1 and #3 produce high-quality GI and GA for both exposed and unexposed applications. 

Multiple Coating Pots - Our HDG lines have dedicated coating pots for each different coating type. This allows for superior control of the pot chemistry. 

Radiant Tube Atmosphere Controlled Furnace – The lines have “Atmosphere Controlled Radiant Tube Heating,” which provides consistent and uniform mechanical properties. 

Rapid Cooling – The lines can quickly and evenly cool the strip after annealing, which produces steel with better strength characteristics and a wider range of mechanical properties.

HDGL #4 Components

Galvalume®, Aluminized & Galvanized Capabilities. AM/NS Calvert has a 550,000 tonne/year light-gauge line which is designed to produce Aluminized, and Galvanized. The line focuses on flatness-critical construction applications as well as high-heat exhaust systems in the automotive segment. 

Multiple Coating Pots – Our HDG line #4 has three coating pots, with each one dedicated to a different coating type, Aluminized or Galvanized. The multiple pot configuration allows for superior control of the pot chemistry, which gives us the ability to offer a superior product to our customers.

Tension Leveler – The line has a tension leveler device located after the in-line Skin Pass Mill (SPM). The tension leveler, combined with the SPM, allows us to offer an extremely flat product, a very critical attribute to the users of Galvanized in the Construction segment.
