Ναι έχουμε λάβει το ενισχύοντας πλέγμα και είμαστε αρκετά ευχαριστημένοι από την ποιότητα. Πολλές ευχαριστίες! Chris

—— Chris Johnson

Έχω διατάξει ντυμένο το σκόνη πλέγμα οθόνης μυγών Τ 316 από Qijie αντίθετα από άλλους, δεν κόβουν ποτέ τις διαταγές και πάντα το ποιοτικό υλικό ανεφοδιασμού σε με.

—— Νεώτερος Venida του Michael

Είχα την πολύ κακή εμπειρία αγοράς με τον προηγούμενο προμηθευτή, γιατί αναβάλλουν πάντα το χρόνο αποστολών. Στον ενθουσιασμό μου, Qijie είναι πάντα ακριβές.

High Durability Zinc Coated Tubes Galvanized Steel Round Tube Square Tube

 

Hot dip galvanized tube is to make molten metal and iron matrix reaction and produce alloy layer, so that the matrix and coating of the combination of the two. Hot dip galvanizing is the first steel pipe pickling, in order to remove iron oxide on the surface of the steel pipe, pickling, through ammonium chloride or zinc chloride aqueous solution or ammonium chloride and zinc chloride mixed aqueous solution tank for cleaning, and then into the hot dip plating tank. Hot dip galvanizing has the advantages of uniform coating, strong adhesion and long service life. Complex physical and chemical reactions occur between hot dip galvanized steel tube and molten plating solution to form a tightly structured zinc-ferroalloy layer with corrosion resistance. The alloy layer is integrated with pure zinc layer and steel tube matrix, so its corrosion resistance is strong.

1.Black square&rectanhgular steel pipe:ERW steel tube
2.Pre-galvanized square&rectangular steel pipe: Pre-galvanized square/rectangular tube is made of hot dipped galvanized steel strip directly.
3.Hot dipped galvanizedsquare&rectangular steel pipe : Hot dipped galvanized square/rectangular tube owns thicker zinc coating than pre-galvanized square/rectangular tube. Black tubes will be dipped into zinc pool for galvanizing.
4.Electro galvanized square&rectangular steel pipe : The technology of electro galvanized square/rectangular tube is similar to hot dipped galvanized tube, but the thickness of zinc coating is less than hot dipped galvanized tube.
5.Painted square&rectangular steel pipe:Painted square/rectangular to remove the rust and clean the oil first and then paint the required color paint.
