PRODUCT DISPLAY
Introduce the galvanized
Galvanized its protective effect is stronger, strong corrosion
resistance. The entire structure is made of zinc, forming dense
tetrad crystals that form a barrier on the steel plate, thus
effectively preventing corrosion agents from penetrating. Corrosion
resistance from zinc barrier layer protection. When zinc
sacrificial protection on cut edges, scratches and coating abrades,
zinc forms an insoluble oxide layer and acts as a barrier
protection.
Galvanized square pipe use
Mainly used in curtain wall, construction, machinery manufacturing,
steel construction projects, shipbuilding, solar power generation
support, steel structure engineering, power engineering, power
plant, agricultural and chemical machinery, glass curtain wall, car
chassis, airport and so on.

APPLICATION
Hot-dip galvanized square pipe and cold galvanized square pipe are
distinguished
There are hot dip galvanized square pipe and electric galvanized
square pipe two categories. Hot dip galvanized square pipe wet,
dry, lead - zinc, REDOX, etc. The main difference between different
hot-dip galvanizing methods is how to activate the surface of steel
pipe to improve galvanizing quality after acid leaching cleaning.
At present, dry method and REDOX method are mainly used in
production, and their characteristics are shown in the table. The
surface of zinc layer is very smooth and compact, and the structure
is uniform. Good mechanical properties and corrosion resistance;
Zinc consumption is 60% ~ 75% lower than hot dip galvanizing.
Electrogalvanizing has certain complexity in technology, but it is
necessary to use this method for single-sided coating, double-sided
coating with different thickness of inner and outer surface
coating, and galvanized thin-walled pipe.
