I. Core Characteristics and Advantages of Steel Structures
High Strength with Light Self-Weight：For commonly used Q235 and Q355 steel, their yield strengths reach 235MPa and 355MPa respectively, with high tensile strength. The strength of steel enables it to bear large loads; at the same time, its self-weight is only 1/3 to 1/4 of that of a concrete structure with the same volume. This characteristic is particularly prominent in long-span buildings and projects with limited foundation bearing capacity, significantly reducing the construction cost of the foundation. For example, in large stadiums, exhibition halls and other buildings, the use of steel structures can easily achieve column-free designs for large spaces.

High Construction Efficiency：Components of steel structures can be accurately prefabricated in factories, then transported to the construction site for assembly via bolts or welding. Compared with the construction of traditional concrete structures, the construction period can be shortened by 40% to 60%. This efficient construction method not only reduces on-site operation time but also minimizes the impact of construction on the surrounding environment, making it particularly suitable for projects with tight schedules.

High Space Utilization：Thanks to the small cross-section yet strong load-bearing capacity of steel, steel structures can create column-free spaces with larger spans. In industrial workshops, this means production equipment can be arranged more flexibly, improving the utilization efficiency of production space; in commercial buildings, it can provide customers with a more spacious and comfortable shopping environment.

Outstanding Environmental Performance：Steel features 100% recyclability and reusability, which endows steel structures with significant advantages in terms of environmental protection. During the construction process, the amount of construction waste generated is reduced by more than 70% compared with concrete structures. This fully complies with the current development concept of green buildings and contributes to sustainable development.

II. Common Types of Steel Structures and Their Applicable Scenarios

Gabled Frame Structure：Composed of gabled frame columns and gabled frame beams, it features a simple structure and rational force bearing. Generally, it is applicable to industrial workshops, warehouses and other buildings with a span of 15-30 meters. This type of structure can meet the space requirements for mechanical production, cargo storage and other scenarios, and its simple structure also makes construction relatively convenient.

Grid Structure：Formed by connecting multiple rods to form a mesh structure, it has excellent seismic and wind-resistant performance. It is often used in large public buildings such as stadiums and exhibition centers with a span of 30-100 meters. For example, the roofs of some large stadiums often adopt grid structures with bolted spherical joints, which not only ensure the sense of space of the building but also resist various natural disasters.

Frame Structure：Composed of beams and columns connected by rigid joints, it has highly flexible spatial layout. It is suitable for multi-story office buildings, commercial complexes and other building types. In these buildings, spaces can be divided freely according to different functional needs to meet diverse usage scenarios such as office work and commerce.

Other Special Types：

Light Steel Structure：It adopts thin-walled steel members, featuring light weight and easy installation, and is often used in low-rise residences, agricultural greenhouses, etc. Its cost-effective and practical characteristics make it widely applied in projects with strict cost control.

Tower Structure：Such as communication towers and power transmission towers, it forms a high-rise structure through the combination of section steel, with good stability and wind resistance, meeting the needs of high-altitude facilities in fields such as communications and electric power.

 Composite Steel Structure：It combines the advantages of steel and concrete; for example, steel-concrete composite beams are often used in bridges, high-rise buildings, etc. This structural form balances strength and economy, playing an important role in different construction scenarios.
