What happens when copper touches galvanized steel?
If an installation requires contact between galvanized materials and copper or brass in a moist or humid environment, rapid corrosion of the zinc may occur. Even runoff water from copper or brass surfaces can contain enough dissolved copper to cause rapid corrosion.
What is better copper or galvanized?
Due to their toughness and extended lifespan, copper pipes are favored by homeowners. Galvanized pipes don't last as long as copper pipes do, which makes copper pipes a better option for residential and commercial uses.
How strong is galvanized steel wire?
The wire has a tensile strength of 145,000 to 175,000 psi, making it perfect for high-stress applications. The galvanized coating gives the wire excellent corrosion resistance, making it ideal for use in environments where corrosion is a concern.
