The design and fabrication of steel structural supports must comply with relevant national and industry standards to ensure their safety, reliability, and durability. Commonly used steel structure design standards in China include the Code for Design of Steel Structures* (GB 50017) and the Code for Acceptance of Construction Quality of Steel Structures* (GB 50205); the former stipulates requirements regarding structural load-bearing capacity, stability, and material selection, while the latter establishes explicit specifications for the construction and acceptance processes.
Furthermore, strict standards govern the materials used for supports as well as welding processes. For instance, carbon structural steel and low-alloy high-strength steel must comply with standards such as Structural Steels (GB/T 700 and GB/T 1591). Welding operations must adhere to the Code for Welding of Steel Structures (GB 50661) and associated construction and acceptance regulations to ensure weld quality and overall structural integrity. Regarding requirements for corrosion protection, fire resistance, and weather resistance, reference should also be made to the *Code for Design of Corrosion Protection for Steel Structures* (GB 50046) and the *Code for Fire Protection Design of Buildings* (GB 50016).
In specialized industrial applications-such as the power, telecommunications, or petrochemical sectors-steel structural supports must also satisfy specific industry standards. For example, the power industry frequently utilizes the Code for Design of Steel Structural Supports for Power Equipment (DL/T 123) along with its accompanying construction and acceptance procedures; these standards impose detailed requirements regarding support loading, vibration resistance, weather resistance, and corrosion resistance, thereby guaranteeing the safety and reliability of the supports throughout their long-term operation.
