Product Specification
Ingredients/Data

Galvanized rectangular pipe is divided into:

Hot-dip galvanized rectangular pipe and electrogalvanized rectangular pipe two categories. Hot-dip galvanized square pipe has wet method, dry method, lead-zinc method, REDOX method and so on. The main difference between different hot dip galvanizing methods is what method is used to activate the surface of the pipe to improve the quality of galvanizing after the acid dip cleaning of the steel pipe. At present, dry method and REDOX method are mainly used in production, and their characteristics are shown in the table. The surface of the zinc layer of electrogalvanizing is very smooth and compact with uniform structure. Good mechanical properties and corrosion resistance; The zinc consumption is 60%~75% lower than that of hot dip galvanizing. Electrogalvanizing has a certain complexity in technology, but this method must be used for single-sided coating, double-sided coating with different thickness of internal and external surface coating, and thin-wall pipe galvanizing.

Acceptance criteria:

Hot-dip galvanized rectangular pipe generally determines whether it is qualified by the appearance of the product, and if there is leakage plating, pitting, white spots, heavy skin, bubbles, green and the frequency is too high on the surface of the square pipe wall, it is judged to be unqualified products. However, in the product standard, the deviation of the product has a specified range, that is, the "allowable deviation" of the size.

Purpose:

Mainly used in curtain wall, construction, machinery manufacturing, steel construction projects, shipbuilding, solar power generation bracket, steel structure engineering, power engineering, power plant, agriculture and chemical machinery, glass curtain wall, automobile chassis, airports and so on.
