2. Long lifespan: the lifespan of the zinc-aluminum-magnesium square tube is about 50 years, and the traditional galvanized square tube is only 20 to 30 years
3. Easy to process: the rectangular tube made of zinc, aluminum and magnesium has excellent wear resistance and scratch resistance, and can be adapted to a variety of processing; the traditional galvanized rectangular tube requires galvanizing, paint touch-up, surface treatment and repeated logistics in the middle, and the process is cumbersome
4.Automatic repair: automatic repair of cutting, stamping and section coatings, reacting with oxygen ions in the air, forming a white protective film on the surface to prevent rust.
5. Environmental protection: Passed a number of international environmental protection tests.
6.Low Cost:cheaper than stainless steel
7.Easy Operation:The thickness, strength and galvanizing amount can be adjusted
