Advantages of Steel Structure Elevators:
High material strength with light weight
High strength and high modulus of elasticity. Compared to concrete and wood, its ratio of density to yield strength is relatively low, so the cross-sectional area of steel structural components is smaller and the weight is lighter under the same load conditions, making it convenient for transportation and installation, suitable for structures with large spans, high heights, and heavy loads.
2. High toughness and plasticity of steel, uniform material, and high structural reliability.
Suited for withstanding impact and dynamic loads, it exhibits excellent seismic performance. The internal microstructure of the steel is uniform, nearly isotropic and homogeneous. The actual working performance of steel structures is quite in line with calculation theories. Therefore, steel structures have high reliability.
3. High degree of mechanization in steel structure manufacturing and installation
Steel structural components are easy to manufacture in factories and assemble on-site. Factory mechanized production of steel structural components ensures high precision, high production efficiency, quick assembly on-site, and a shorter construction period. Steel structures are a type of structure with a high degree of industrialization.
4. Good sealing performance of steel structure
Due to the ability to achieve complete sealing, welding structures can be made into high-pressure containers with excellent gas and water tightness, large oil tanks, pressure pipelines, and more.
5. Steel structures are heat-resistant but not fire-resistant.
At temperatures below 150°C, the properties of steel change minimally. Therefore, steel structures are suitable for hot workshops; however, when the surface of the structure is exposed to heat radiation around 150°C, insulation boards should be used for protection. At temperatures of 300°C to 400°C, both the strength and elastic modulus of steel significantly decrease, and at around 600°C, the strength of steel approaches zero. In buildings with special fire protection requirements, steel structures must be protected with refractory materials to enhance their fire resistance rating.
6. Poor corrosion resistance of steel structure
Especially in environments with humidity and corrosive media, rusting is prone to occur. General steel structures require rust removal, galvanizing, or coating, and regular maintenance is necessary. For offshore platform structures in seawater, special measures such as "zinc block anodic protection" should be employed to prevent corrosion.
7. Low-carbon, energy-saving, and environmentally friendly, reusable
Structural steel building demolition generates almost no construction waste, and the steel can be recycled and reused.
