Product Description
Galvanized Fire Pipes are carbon steel pipes coated with zinc to prevent rust and corrosion in wet or humid environments. These pipes are widely used in wet fire sprinkler systems, where constant water exposure is expected.
They are manufactured in accordance with standards like ASTM A795 / A53 / A135, and are available in hot-dip galvanized (HDG) or electro-galvanized finishes. Grooved or threaded ends are available to suit installation requirements.
