STRUCTURE HOT-DIP GALVANIZED SQUARE PIPE
What is hot-dip galvanized square tube？
Hot dip galvanized square tube is to make molten metal react with iron matrix to produce alloy layer, so that the matrix and coating can be combined. Hot galvanizing refers to pickling the steel pipe first. In order to remove iron oxide on the steel pipe surface, after pickling, the steel pipe is cleaned in ammonium chloride or zinc chloride aqueous solution or mixed ammonium chloride and zinc chloride aqueous solution tank, and then sent to the hot dip tank. Hot dip galvanized square tube has the advantages of uniform coating, strong adhesion and long service life.
Use of hot-dip galvanized square pipe？
Hot dip galvanized square and rectangular tubes are widely used in manufacturing industries such as construction, machinery, coal mines, chemical industry, railway vehicles, automobile industry, highways, bridges, containers, sports facilities, agricultural machinery, petroleum machinery, exploration machinery, etc.
Galvanized square pipe is a name for square pipe and rectangular pipe, that is, steel pipe with equal side length. It is made of rolled strip steel after process treatment. Generally, the strip steel is unpacked, leveled, crimped, welded to form a round pipe, then rolled into a square pipe from the round pipe and then cut into the required length. Generally 50 pieces per package. Also known as square and rectangular cold-formed hollow section steel, referred to as square pipe and rectangular pipe, code f and j respectively

Q5：How to prolong the service life of hot-dip galvanized square pipe?In fact, if we want to use it for a longer time, our usual maintenance is indispensable. Our square tubes can be pickled, which is mainly to remove some stains on the surface of our hot-dip galvanized square tubes. But after pickling, we also want them to be cleaned again with an ammonium chloride or zinc chloride aqueous solution, and then put them in the hot dip tank. After so many maintenance steps, our hot-dip galvanized square tube can be used for a long time.
