Why Is Copper Thickness Called Out by the Ounce and Not the Actual Thickness?
The ounce represents the weight per square foot for the stated material. For example, 32oz (.042) thick is twice as thick as 16oz. (.021) thick. The following list is an example of the methods IMS uses to measure different materials:
- Steel: Gauge
- Galvanized steel: Gauge
- Stainless steel: Gauge
- Aluminum: Decimal (i.e. .032 or .060)
- Brass: Decimal
- Copper: Ounces (Lbs. per sq/ft)
