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.
