Galvalume (GL) Steel Coils

Galvalume (GL) is a metallic coated carbon steel product that has proven its superior performance as a corrosion resistant building material in extended field testing in a diverse range of environments. The Galvalume coating is an alloy composed of 55% Aluminium and approximately 45% zinc by weight. It is applied on both sides of cold-rolled steel sheet using a precise continuous hot dip process. The result is highly corrosion resistant coated steel that combines the barrier protection and extended durability of Aluminium with the galvanic protection of zinc.

 

Advantages of Galvalume coating :

  • At least twice the corrosion resistance of traditional galvanized coatings of similar thickness under the same exposure conditions
  • Excellent corrosion protection at cut edges
  • A distinctive appearance, with a smooth, fine spangle and silvery metallic appearance
  • Exceptional solar reflectance, resulting in lower energy load on buildings and improved interior comfort
  • High temperature resistance

 

Applications :

  • Roofing
  • Trusses
  • Spandeck
  • Trimdeck
  • Batten
  • Hollow
  • Gutter
