Galvanized steel grille

After the production of zinc steel steel grid and steel grid plate, rust prevention treatment should be carried out. There are two kinds of hot dip galvanizing and electric galvanizing. Hot-dip galvanizing standard: GB/T 13912-2002 hot-dip galvanizing steel parts technical requirements and experimental methods Steel grid plate as a new material, new products are being increasingly widely used, its more superior performance and good performance-to-price ratio shows its application prospects. This paper discusses the performance of steel grid plate, the economic selection of steel grid plate and its comprehensive technical and economic analysis. In metallurgy, mining, petroleum, electric power and industrial fields as well as some civil fields, steel grid as a new building materials is being increasingly widely used. The so-called new materials, in fact, have a history of more than decades in foreign countries, but it has only been widely used in China for nearly 10 years. But just like aluminum alloy doors and Windows, compared with traditional materials, people are used to calling it a new material.

Scope of use

Galvanized steel grille is suitable for alloys, building materials, power stations, boilers, shipbuilding, petrochemical, chemical and general industrial plants, municipal construction and other industries, with ventilation and light, anti-slip, strong bearing capacity, beautiful and durable, easy to clean, easy to install and other advantages. At present, steel grid has been widely used in all walks of life at home and abroad, Mainly used as industrial platform, ladder pedal, banisters, passage floor, railway bridge side, overhead tower platform, gutter cover, manhole cover, road barrier, three-dimensional parking lot, organs, schools, factories, enterprises, sports fields, garden villa fence, can also be used as residential Windows, balcony guardrail, highway, railway guardrail and so on.

Processing mode

Electrogalvanizing and hot-dip galvanizing

We often say that there are two kinds of galvanized steel grid plate: pay attention to the difference hot-dip galvanized ----, also known as hot-dip galvanized, he is to melt the zinc ingots at high temperatures, put some auxiliary materials in, and then dip the metal structure into the galvanized tank, so that the metal component is attached to a layer of zinc layer. The advantage of hot dip galvanizing is that it has a strong anti-corrosion ability, and the adhesion and hardness of the galvanizing layer are better. The weight of the product has increased after galvanizing, and the amount of zinc we often say is mainly for hot dip galvanizing. "Cold plating" ---- "electroplating", that is, the zinc salt solution through electrolysis, so that iron ions and zinc ions are replaced to reflect, generally speaking, there is no heating, the amount of zinc is little, and it is easy to rust in wet environment.
