Commodity: Galvanized Square Tubing
The galvanized square tubings are available in two categories: hot-dip galvanized square tubes and electro-galvanized square tubes. The hot-dip galvanized tube has a wet method, a dry method, a lead-zinc method, a redox method, and the like. Electrogalvanizing is to make the zinc powder and the steel material fully contact, resulting in electrode potential difference. The surface of the zinc electroplated layer is very smooth and compact, and has a uniform structure; it has good mechanical properties and corrosion resistance.
Due to the galvanizing treatment on the steel, the application range of the square tube has been greatly expanded compared with the square tube.

1. Since the galvanized square tubing is hot-dip galvanized on the basis of the welded square tube, the galvanized tube has stronger protection effect than the ordinary welded square tube and has strong corrosion resistance.
2. The hot-dip square tube is processed by a very advanced infusion galvanizing process, which makes the surface of the material white and beautiful, and there are absolutely no defects such as leakage iron, leakage plating and scarring, allowing the hot-dip galvanized tube to have a very uniform surface.
3. The galvanized steel pipe has excellent impact resistance and can be used to transport liquids.
4. It has good anti-wear performance during use, and the paint layer of the material is not damaged for a long time, prolonging the service life of the material.
