Steel Space Frame Structure Supplier - SAFS

                 Steel structures are widely used in the construction industry, but many people do not understand the difference between HN and HW steel structures. What role do they play in steel structures? SAFS steel structure engineering company will take you to understand: The difference between HN and HW: H-beam is welded, HM, HN, HW are hot-rolled. HM is called middle flange H-beam, and the ratio of H-beam height to flange width is 1.33-1.75. It is mainly used as steel frame column in steel structure. Used as frame beams in load-bearing frame structures, such as equipment platforms. HW is called wide flange H-beam, and the height of the H-beam is basically equal to the width of the flange. It is mainly used for steel core columns in reinforced frame structures, also known as rigid steel columns, and is mainly used for columns in steel structures. WH270*250*18*23 is for welding H-beam W is the first letter of welding. After reading the above introduction, do you have a certain un

         What are the standards for building gas stations with steel sapce frame  structure? Let's take a look. The most important material used in the construction of gas station sapce frame s is steel sapce frame . Therefore, the quality of the steel structure used is directly related to the quality of the mesh frame. The steel mesh frame structure used by users in the renovation of the roof of the gas station must meet the following points before they can be built:   Steel Structure Space Frame Gas Station 1.  The welding wire to be used in the installation of the steel mesh frame should be checked for the quality certificate before installation. The written content should fill in the actual inspection results of the manufacturer, especially the chemical composition of the welding wire, the mechanical properties of the deposited metal, the radiographic inspection results of the welding seam, and the imprint of the technical supervision department. Also pay attention to check the

        When we have not been exposed to the steel structure industry, we must not know much about it. But for professionals, they must know the reason. The same is true for steel structure space frame , so why should large-span steel structure projects be reinforced? 1. Changes in process operations cause changes in the structural layout and stress conditions of steel structures; 2. The increase of load (such as adding insulation layer to the roof of steel structure buildings, increasing the lifting capacity of cranes in steel structure workshops, or adding cranes to workshops without cranes, etc.); 3. Accidental damage, such as war damage, damage caused by natural disasters (such as earthquakes); 4. Various defects due to poor design consideration or design errors, as well as construction quality accidents of steel structure buildings. For example, the design of the truss gusset plate does not consider the construction assembly error, resulting in insufficient length of the welding s

  Building a steel structure canopy can be used to park our mobility vehicles, so that the vehicle can reduce corrosion and protect it from the wind and rain. So how should we design the steel structure canopy? SAFS steel structure is introduced here. steel structure canopy   To make a steel structure canopy, it is necessary to prepare a suitable amount of reliable materials. The rigid standard used in the entire canopy is divided into load-bearing steel columns, and 10cm*10cm square pipes are used, while the requirements for beams are slightly lower. The square tube of 4cm*8cm, and then the top of the canopy, can choose the membrane structure, which is more durable.   For welding, electrodes, wires, and fluxes are all indispensable materials. After purchasing these materials, you can start construction.   Before the steel frame is erected, the iron is pre-buried. After the steel plate is buried in the ground, use an electric welding machine and a level to ensure the level of the steel
