  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 ...

  Main inspection contents in steel structure engineering: The components used in steel structures are generally mass-produced by steel mills and are required to have certificates of conformity, so the strength and chemical composition of the materials are well guaranteed. The focus of engineering inspection is on the quality problems generated during the installation and splicing process. The main testing contents in the steel structure project are: (1) Detection of member size and flatness; (2) Detection of surface defects of members; (3) Detection of connection (welding, bolting); (4) Detection of steel corrosion; (5) Fireproof coating thickness test. If there is no factory certificate of conformity for the steel, or if there is doubt about its quality, the mechanical properties test of the steel should be increased, and if necessary, its chemical composition should be tested.  (1) Detection of member size and flatness For each size in the member of the 3 parts of the meas...

  Arch roofs   need to be designed with several factors in mind to ensure their structural stability, aesthetics, and functionality. Below are some of the main points to consider: 1. Structural stability: The arch design must be able to withstand external forces such as self-weight, snow load, wind pressure, etc. to ensure the stability and safety of the structure. Designers need to calculate the force on the arch structure at different points and design suitable support and reinforcement measures. 2. Material selection: Choosing the right building materials is key. The materials need to be strong and durable enough to withstand the expected loads. Steel is a common choice, they can provide good load-bearing capacity and weather resistance. 3. Force analysis: The stability of an arch structure depends on its shape and the way it is stressed. Each part of the arch is subjected to pressures that need to be evenly distributed through the footings into the foundation. Therefore, a...

Control points for acceptance of raw materials and finished products on-site ① Steel: should be based on the design requirements to specify the choice of steel grade, reference standard number, chemical composition, and physical properties of the index. Raw material suppliers should provide a complete quality assurance certificate and material test reports. The varieties, specifications, and performance of steel and steel castings should be in line with the current national product standards and design requirements, and the quality of imported steel should be in line with the requirements of design and contractual standards. Supervision shall require the steel structure contractor to submit quality certification documents, Chinese marks, and inspection reports to the supervisor for review, and the supervising engineer shall check all of them. ② Welding materials: the varieties, specifications and performance of welding materials shall meet the current national product standards and des...
