Pipe
CONDUCTION PIPE, BLACK OR GALVANIZED
Conduction pipe is produced using the hot-reduction method, which allows the steel to normalize and obtain qualities ideal for the conduction of liquids and gases. The pipe is hot-dip galvanized, which guarantees uniform coating interior and exterior surfaces and provides corrosion resistance superior to that of other processes.
