Dalian Kairui Metal Products Company is a manufacturer specializing in the production of traffic guardrails. The municipal traffic guardrails produced by this unit can be divided into zinc steel guardrails, traffic guardrails, Beijing-style guardrails, etc. according to their materials. The product features are as follows:
According to custom, the hot-dip galvanizing process is divided into two categories: off-line annealing and in-line annealing based on different pre-plating treatment methods. In recent years, hot-dip galvanized guardrail nets have been used in many fields. The advantage of hot-dip galvanized guardrail nets is that they have a long anti-corrosion life and are widely adaptable to the environment. It has always been a very popular anti-corrosion treatment method. It is widely used in power towers, communication towers, railways, highway guardrails, street light poles, marine components, building steel structure components, substation ancillary facilities, light industry, etc. >
Due to the long anti-corrosion life of hot-dip galvanized guardrail nets, the anti-corrosion life is different in different environments: heavy industrial area years, ocean years, suburban years, and city years. The principle of hot-dip galvanizing treatment for highway guardrail nets: clean the welded mesh, then treat it with solvent, dry it and then immerse it in zinc liquid. The welded mesh reacts with molten zinc to form an alloyed zinc layer. The process is: Degreasing, water washing, pickling, aid plating, drying, hot dip galvanizing, separation, cooling and passivation. The thickness of the hot-dip galvanized alloy layer for railway guardrail mainly depends on the chemical composition such as silicon content of the steel, the cross-sectional area of the steel, the roughness of the steel surface, the temperature of the zinc pot, the zinc immersion time, the cooling speed, and cold rolling Deformation etc. The product specifications and models are complete and can be customized according to customer needs. New and old customers are welcome to come to discuss cooperation>!
