1、In terms of steel structural characteristics, the steel plates exhibit good ductility and plastic deformation, with uniform material distribution. This leads to high structural reliability, making them suitable for bearing impact-driven loads and possessing excellent seismic performance ratings. The internal structure of steel plates is uniform, tending towards isotropic homogeneity. The performance of steel structures in specific operational conditions aligns well with calculated theoretical foundations. Therefore, steel structures demonstrate high reliability.
2、In comparison to concrete and wood, steel structures have a smaller cross-section and lighter weight due to the high compressive strength of raw materials, low relative density, and high tensile strength of bolts and elastic modulus. This makes them suitable for structures with large spans, high aspect ratios, and heavy loads, facilitating transportation and installation under the same load-bearing standards.
3、Steel structures offer excellent sealing performance due to the thorough sealing achieved through electric welding. They can be fabricated into pressure vessels with excellent sealing and pressure containment capabilities, suitable for large and medium-sized oil tanks, Class II pressure vessels, and similar applications.
4、In steel structures, resistance to high temperatures does not imply fire resistance. When the temperature is below 150°C, the characteristics of stainless steel plates undergo minimal changes. Therefore, steel structures are suitable for use in hot production workshops. However, when the surface of the structure is exposed to thermal radiation between 150°C to 300°C, it is necessary to employ various insulation materials for maintenance. At temperatures between 300°C to 400°C, both the strength of bolts and the modulus of elasticity significantly decrease. When the temperature reaches around 600°C, the compressive strength of stainless steel plates tends towards zero. In engineering constructions with unique fire safety requirements, steel structures must utilize fire-resistant insulation materials extensively to enhance the fire rating.
5、Steel structures are known to have poor corrosion resistance, especially in wet and cold environments with corrosive substances, making them prone to rust. Typically, steel structures require rust prevention treatment, hot-dip galvanizing, or architectural coatings, and they need regular maintenance. For offshore platforms situated in marine environments, unique corrosion-resistant measures such as 'zinc block anode protection' are necessary.
6、Steel structure production, manufacturing, and installation boast high levels of automation. Steel structural components contribute significantly to production and assembly in manufacturing plants and construction sites. Automated machinery in manufacturing plants ensures high precision in the production of steel structural components, leading to high productivity. As a result, assembly speed at construction sites is accelerated, meeting tight project deadlines. Steel structures represent one of the most advanced structural solutions in modern construction practices.
