The higher the carbon content, the higher the hardness of the steel, but the worse its plasticity and toughness.

During the tensile process of the sample, the maximum force (Fb) it is subjected to when it breaks, divided by the original cross-sectional area of th

Cold galvanized pipe is electric galvanized, galvanized amount is very small, only 10-50g/m2, its own corrosion resistance is much different than hot

Hot dip galvanized pipe is the reaction of molten metal with iron matrix to produce alloy layer, so that the matrix and the coating are combined.

Galvanized steel pipe Welded steel pipe with hot dip plating or electrogalvanized coating on the surface.

Galvanizing has stronger protective effect and strong corrosion resistance.

Because the galvanized square pipe is galvanized on the square pipe, the application range of galvanized square pipe has been greatly expanded compare

Galvanized square pipe has two categories: hot-dip galvanized square pipe and electric galvanized square pipe.

Galvanized square pipe from the production process is divided into hot galvanized square pipe and cold galvanized square pipe.
