Weight of galvanized layer - "red line indicator"

In the new national standard, the zinc layer weight of galvanized steel pipes first proposed the "bottom line requirements"! Namely: In the old version of the standard only on the basis of "negotiating terms required" on the basis of an increase of "the internal and external surface of the steel galvanized layer per unit area of the total weight should not be less than 300g/m2" mandatory standards.

As a result, the average life of the steel pipe is at least 30% longer.
