tianjin galvanized square tube chinese galvanized
galvanized square tube has two categories: hot-dip galvanized square tube and electro-galvanized square tube. hot-dip galvanized square tube has wet method, dry method, lead-zinc method, redox method and so on. the main difference between different hot-dip galvanizing methods is how to activate the surface of the pipe to improve galvanizing quality after the pickling of steel pipes. the main production methods are dry method and redox method. the characteristics are shown in the table. zinc electroplated zinc surface is very smooth and dense, uniform structure; has good mechanical properties and corrosion resistance; zinc consumption is 60% to 75% lower than hot-dip galvanizing. zinc electroplating has certain technical complexity, but this method must be used for single-sided plating, double-sided plating with different coating thickness on the inner and outer surfaces, and thin-walled tube galvanizing.
as the galvanized square tube is galvanized on the square tube, the scope of application of the galvanized square tube has been greatly expanded compared with the square tube. it is mainly used for curtain wall, construction, machinery manufacturing, iron and steel construction projects, shipbuilding, solar power support, steel structure engineering, power engineering, power plants, agriculture and chemical machinery, glass curtain walls, car chassis, airports and so on.

galvanizing has stronger protection and corrosion resistance. the entire structure consists of zinc, forming a dense quaternary crystal, which forms a barrier on the steel plate, thus effectively preventing penetration of corrosion factors. corrosion resistance the barrier layer from zinc has a strong protective function. when zinc is sacrificially protected by trimming, scratches, and scratches on the plated layer, zinc forms an insoluble oxide layer and functions as a barrier.
