| 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
- Spangle can be specified "Small-Minimum" or "Large"
- 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 |
- 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
