What are all the ways of corrosion protection for structural steel materials?

 Anti-corrosion of steel structure materials is very important because steel is prone to rusting in a humid environment, and rusting destroys the strength and durability of the steel structure. Here are some common ways of corrosion prevention:



  • Hot-dip galvanizing anticorrosion method: This is a commonly used anticorrosion method to prevent corrosion by dipping the steel into melted zinc solution so that the steel surface is attached to a zinc layer. The advantages of this method are long durability, high industrialization of production, and stable quality.
  • Paint anticorrosion method: the surface of the steel is first painted with primer, and after the primer dries and solidifies, the topcoat is then painted. This method is mainly used for indoor steel treatment.
  • Arc Spraying Anti-corrosion Method: First polish and descale the components, then beat the hair, then ignite the arc to melt the metal material, and spray paint it on the pre-polished components to achieve the effect of corrosion and wear resistance.
  • Use of weathering steel: Weathering steel has better corrosion resistance compared to ordinary steel.

The above methods have their own characteristics and are suitable for different environments and uses. In practical application, the appropriate anti-corrosion method should be selected according to the specific situation.

Several cutting methods of steel structure space frame

图片
  Steel st ructure space frame s are now widely used, such as galvanized steel warehouse , glass dome building , airport hangar ,steel structure warehouses, hall roofs, gymnasiums, etc. The builder will cut, produce, and process according to the customer's requirements. There are many ways to cut steel structure space frame s, which will help you to have more choices of cutting. Then, the space frame   manufacturers below will give us a detailed description of several common cutting methods. The cutting methods of the steel structure space frame   are as follows: 1. Flame cutting by CNC machine tools: that is to say, use oxygen cylinders to oxidize and melt steel at a high temperature continuously. At present, natural gas is generally available, which is relatively reliable. 2. Waterjet cutting machine: Generally, high-pressure flowing water is used for cutting, and the accuracy is very high. It is often cut in some very thin, medium-thick steel that requires precision m...

What are the advantages of steel over traditional concrete?

  steel warehouse Steel structures offer several advantages over traditional concrete structures that cover a wide range of areas, including speed of construction, flexibility, sustainability, and more. Here are some common advantages of steel construction:   Lightweight and High Strength: Steel is a lightweight and strong building material. Compared to concrete, the use of steel reduces the dead weight of the building, which in turn reduces the load on the foundation and lowers the overall weight of the building.   Fast construction: Steel structures can be prefabricated in a factory and then simply assembled on site. In contrast, traditional concrete structures typically require more on-site pouring and maintenance time. As a result, steel structures are often faster to construct, helping to shorten project duration.   Design Flexibility: Steel structures are strong and malleable and can support large spans and diverse building designs. This gives designers more f...

  With the continuous improvement of socialist productivity, various industries are developing in the direction of rapid development, so is the steel space frame engineering industry. Due to the Therefore, we should attach great importance to the  space frame cost  management, because the project involves many aspects and fields, and only through reasonable project space frame cost management, can we ensure the quality of the last step of the project. Therefore, we should fully realize that dynamic management and control of project cost is a very important work content and link. In order to improve the quality level of steel grid engineering, dynamic management and control of project cost should be further strengthened. Optimizing the investment process is the most critical link in the steel space frame. the same time, it is also a very important aspect in the process of space frame construction cost management. Therefore, active and effective measures should be take...
