Galvanized & Galvannealed Steel

GALVANIZED
GALVANNEALED (PAINT BONDABLE)

 

GALVANIZED 
GALVANIZED
  • ASTM-A653
  • Sheet .135 and thinner
  • Mild Steel / Low Carbon
  • Galvanized Coating resists corrosion
  • Air Conditioning and Heating  and Ventilation Ducts
  • Good Bending
  • Welding can cause dangerous fumes
  • Spangle = surface snowflake-like pattern
  • Different manufacturers offer different Spangle
  • Coating Thickness Designated as G60 or G90
COATING THICKNESS
  • G60 = 0.60 Ounce Per Square Foot (Total Both Sides)
  • G90 = 0.90 Ounce Per Square Foot (Total Both Sides)

GALVANNEALED
GALVANNEALED 
  • Combined process of galvanizing and annealing
  • line annealing creates very fine greyish matte finish
  • Coating does not flake off when formed
  • Matte finish acts as primer allowing paint to adhere
  • Very rust proof
  • Good paintability and weldability
  • Good corrosion resistance and formability
  • Used in automotive, signage and electric equipment
  • Trade Names = Jet-Kote and Redi-Coat
