High Strength Bolt Friction Surface Corrosion Hot Galvanized Steel Pipe ASTM DX51D
Detail:
Can galvanized steel handle high heat?
High temperatures above 480 F (250 C) will accelerate peeling and continued exposure can result in the zinc-iron alloy layers cracking and separating from the steel. Temperature applications of hot-dip galvanized steel above 480 F (250 C) are not recommended.
What is hot dip galvanized pipe?
The Hot Dip Galvanized Pipes are made using quality steel metal with a galvanized coating. These pipes are coated with additional layer of zinc by plunging the metal in a bath of molten zinc at quite a high temperature. The hot dip galvanized pipes are preferred over others as these have superior corrosion resistance.
