The galvanized steel grating is the rustproof treatment after the steel grating is produced. The hot-dip galvanizing specification is: GB/T 13912-2002 "Steel galvanizing technology request and test method" steel slab as a new data, new products are being used more and more widely, and its more superior functions and The outstanding feature price ratio shows the vision of its use. The article discusses the function of steel grating, the economic selection of steel grating and its technical and economic analysis. In the metallurgical, mining, petroleum, electric power and industrial categories as well as some civil categories, steel gratings are increasingly being used as a new type of building materials. The so-called new materials have been in foreign countries for more than a decade, but they have been widely used in China for only about 10 years. But like aluminum alloy doors and windows, compared with traditional materials, people are still used to refer to it as new information.
Hot-dip galvanizing----also known as hot-dip galvanizing. He melts the zinc ingot at high temperature, puts some auxiliary materials, and then immerses the metal structural member in the galvanizing tank to attach a layer to the metal member. Zinc layer. The advantage of hot-dip galvanizing is that it has strong anti-corrosion ability, and the adhesion and hardness of the galvanized layer are good. After the product is galvanized, the amount of zinc has increased. We often say that the amount of zinc is mainly for hot-dip galvanizing.
"Cold plating"----"Electroplating", that is, the zinc salt solution is electrolyzed to reflect the replacement of iron ions and zinc ions. Generally, it does not need to be heated, the amount of zinc on the surface is very small, and it is very simple to rust in a humid environment.
