HOW TO USE GALVALUME® FOR YOUR METAL ROOF
One of the best features of a metal roof is its durability. You may have heard of GALVALUME while searching for metal roof materials. It’s a specific galvanized sheet metal product coated with a mixture of aluminum and zinc alloy with a touch of silicon. It was developed by Bethlehem Steel in 1972, and nearly all large steel manufacturers produce it using their patents. GALVALUME® is only one trademarked name for the material and the process; others include ZINCALUME (Steelcase, LLC) and Galval, Cincalum, or Zintro-Alum (Ternium USA and Ternium Mexico). GALVALUME PRODUCTION GALVALUME is produced through a continuous hot-dip process in which coils of cold-rolled steel are laid out, cleaned, and welded into one long piece. The sheet is placed on a coating line that can run as fast as 600 feet per minute and moves the sheet through the hot dip process.
