Widely used in chemical, assembly of medical equipment, installation of outdoor products. Quality from the practice we must understand excellence, high-quality services in place of philosophy, we constantly go hand in hand with suppliers and customers, mutual encouragement to reach the realm of perfection. 2, "high quality, reasonable price" is our commitment to you. Specializing in the production of stainless steel bolts and nuts and flat washers. Along with the industry found that hot dip galvanized products have been used in many areas, the advantages of hot dip galvanizing is a long time to adapt to the environment protection, has been widely anticorrosive treatment method is very popular. Is widely used in power transmission tower, communication tower, railway, highway, street lamp pole, marine parts, construction steel structure component, the substation ancillary facilities, light industry etc.. Hot dip galvanized anti-corrosion life long, but in the different environment of the anticorrosion time is not the same: heavy industrial region of 13 years, 50 years on the outskirts of ocean, 104 years, 30 years in the city. Hot dip galvanized principle: Iron clean, and then the solvent treatment, drying after immersed in liquid zinc, zinc layer generates a alloyed iron and molten zinc reaction, The procedure is: -- -- -- washing degreasing pickling galvanizing plating - drying - - Separation - cooling passivation. The chemical composition of alloy layer thickness of hot dip galvanized steel mainly depends on the content of silicon, cross-sectional size of steel, the roughness of steel surface, the zinc pot temperature, immersion time, cooling speed, cold rolling deformation etc.. The advantages of hot dip galvanized 1, low processing costs: hot dipped galvanized antirust costs than other coatings of low cost; 2, durable: in the rural environment, hot-dip galvanized thickness standards can be maintained for more than 50 years without repair; in urban or offshore, hot-dip galvanized layer of standard can keep 20 years without repair; 3, good reliability: galvanized layer and steel is metallurgical combination, become a part of the surface of steel, so persistent coating is reliable; 4, coating toughness: galvanized layer formed a special metallurgical structure, the structure can withstand the mechanical damage in transit and when in use; 5, comprehensive protection: each part plating can be plated with zinc, can fully protected even in sharp corners and hiding place; 6, time and labor saving: galvanized process faster than other coating construction method of agile, and can avoid the installation after brushing at the site of the the time required for.
