1. Excellent structural performance, outstanding load-bearing and earthquake resistance
Equipment steel structures are made of high-strength steel with a yield strength exceeding 345 MPa, meaning each square millimeter of steel can withstand a force of 345 Newtons. This characteristic makes them excellent for applications requiring enormous loads, such as large-scale industrial equipment, wind turbines, and bridges. For example, the steel structure of the Beijing Daxing International Airport terminal building was prefabricated by a specialized fabrication plant. High-precision stress simulation analysis ensured the stability of the column-free structure, spanning 1,000 meters, and capable of withstanding a magnitude 8 earthquake and a force 12 typhoon.
Steel's plastic toughness further enhances structural safety. Under earthquake or impact loads, steel structures absorb energy through plastic deformation, preventing brittle fracture. For example, a tank platform at a chemical company, constructed using Q345B steel, survived a simulated earthquake test, even after deformations of 1.5 times its design value. Traditional concrete structures, however, suffered severe cracking under the same conditions. Furthermore, steel structures weigh only 50%-60% of concrete structures, significantly reducing foundation costs and making them particularly suitable for soft soil foundations or high-rise equipment platforms.
2. Industrialized Production: Efficient, Significant Precision and Cycle Time Advantages
Equipment steel structure processing utilizes a highly prefabricated model, shifting cutting, welding, and assembly processes to the factory. Qingdao Ruichen Electric Power Environmental Protection Equipment, for example, uses laser cutting machines and automated welding robots on its production line to maintain component dimensional tolerances within ±1mm, far exceeding the ±5mm standard typically required for on-site construction. This precision advantage is particularly crucial in wind turbine equipment installation. One offshore wind turbine project, facing rework due to excessive steel tower splicing errors, used prefabricated components to achieve a successful first-time installation, saving 20 days.
A shortened construction cycle is another major advantage. Traditional concrete equipment foundations require a 28-day curing period, while steel foundations can support equipment in just 7 days. In an automobile manufacturing plant expansion project, the use of a steel-structured equipment platform shortened the construction period by 45% compared to a concrete-structured one, enabling the production line to begin operations three months earlier and increasing annual output value by over 50 million yuan. Furthermore, factory-based production reduced on-site wet work and mitigated the impact of inclement weather, such as rainy seasons and high temperatures, on construction, increasing the project's contract fulfillment rate to over 98%.
3. Prioritizing both economic efficiency and environmental performance, optimizing lifecycle costs
While the unit cost of a steel-structured equipment platform is 10%-15% higher than that of a concrete-structured one, the overall lifecycle cost is lower. Over a 10-year lifecycle, maintenance costs for steel structures are only 30% of those for concrete, primarily due to their corrosion-resistant coating and replaceable components. Statistics from a steel company show that the average annual maintenance cost for their steel-structured equipment platform is 8 yuan per square meter, compared to 25 yuan per square meter for concrete structures.
Regarding environmental performance, the steel recycling rate is over 90%. Dismantled steel structures can be melted and remanufactured, reducing carbon dioxide emissions by 1.6 tons per ton of recycled steel. In a chemical park renovation project, 3,000 tons of dismantled steel structures were recycled, with 85% used for new equipment frames. This saved 12 million yuan in steel procurement costs and reduced landfill volume by 24,000 cubic meters of construction waste. Furthermore, dust emissions from steel structure construction were 60% lower than those from concrete structures, meeting green building standards.
4. Customization and Flexibility: Adapting to Complex Industrial Needs
Equipment steel structures can be customized based on equipment size and load distribution. Finite element analysis optimized the truss layout of the catalytic cracking unit frame in a petroleum refining project, reducing material usage by 18% while also keeping vibration frequencies outside the equipment's operating frequency range, eliminating the risk of resonance. Modular design further enhances adaptability. A logistics center utilizes standard unit steel structures, allowing for rapid reconfiguration of rack layouts based on business changes, increasing space utilization by 40%.
For applications in extreme environments, steel structures offer customized protection through technologies such as anti-corrosion coatings and thermal insulation interlayers. Steel structures at coastal chemical companies feature zinc-based epoxy coatings, which withstand 5,000 hours of salt spray testing and extend their service life to 25 years. Molybdenum is added to the steel structures of high-temperature steelmaking workshops to enhance their heat resistance, maintaining 80% of their strength at 600°C. This flexibility makes steel structures the preferred structural form for specialized applications such as offshore platforms and polar research stations.
