Product Description

Low-carbon High-efficiency and Flexible Steel Structure Buildings

Ⅰ. Industry Trend: Steel Structures Leading the Transformation of the Construction Industry

Driven by the "dual carbon" goals and prefabricated construction policies, steel structures are gradually replacing traditional concrete structures to become the core direction of the construction industry's upgrading, thanks to their characteristics of low carbon footprint, high efficiency and flexibility.

According to industry data, the proportion of steel structure buildings in China has increased from 5% in 2015 to 18% in 2024, and is expected to exceed 30% by 2030. Their core advantages lie in industrialized production and modular assembly, which can reduce building energy consumption by more than 30% and construction waste by over 70%. Perfectly aligning with the modern construction demands for environmental protection, rapid delivery and recyclability, steel structures are widely applied in diverse fields such as industry, civil engineering and new energy, ushering in a new era of "low-carbon construction" for the building sector.

Ⅱ. Technical Features: Four Core Technologies Define the Value of Steel Structures

Material Technology: Dual Breakthroughs in High Strength and Weather Resistance

High-strength steel grades such as Q355B and Q460 are adopted, with a tensile strength of 355–460 MPa. Compared with traditional Q235 steel, the cross-section of components can be reduced by 20%–30% under the same load-bearing requirements, significantly decreasing the building’s self-weight (the self-weight of a steel structure building is only 1/3–1/2 that of a concrete structure).

Meanwhile, dual anti-corrosion treatment combining hot-dip galvanizing and fluorocarbon coating greatly enhances weather resistance. The service life can exceed 40 years in marine climate zones (high salt spray environments) and even surpass 50 years in arid inland areas, solving the long-standing pain points of traditional steel structures: prone to corrosion and frequent maintenance needs.

Design Technology: Integration of Digitalization and Customization

Full-process digital design is realized based on BIM (Building Information Modeling) technology. From parametric modeling of components to construction simulation, potential issues such as pipeline conflicts and installation errors can be accurately avoided, achieving a design precision of millimeters.

Tailored full-customization design is supported for diverse scenario requirements. For example, large-span warehousing projects can adopt a composite structure of steel trusses and portal rigid frames to create column-free spaces spanning 30–60 meters; multi-story workshops can utilize a steel frame and bracing system to meet the industrial floor load-bearing demand of 500–1000 kg/㎡. The design cycle is shortened by over 40% compared with traditional methods.

Production Technology: Parallel Advancement of Industrialization and Standardization

Steel components are manufactured on automated production lines: CNC cutting equipment ensures precise blanking of components (with an error ≤ 1mm); H-beam assembling machines and submerged arc welding machines guarantee welding quality (with a weld flaw detection pass rate of 99.8%); shot blasting derusting equipment standardizes surface treatment.

All components are produced following the workflow of factory prefabrication → numbered delivery → on-site assembly, with a prefabrication rate of over 90%. They can be delivered in batches according to project schedules, eliminating inefficiencies and quality inconsistencies caused by on-site processing.

Installation Technology: Innovation in Modularization and Lightweight Design

An innovative modular hoisting technology is adopted. Steel columns, beams, roof systems and other components are pre-assembled into modular units (with the weight of a single unit controlled at 5–10 tons), which are then rapidly installed using truck cranes or crawler cranes. The installation time for a single module is only 30–60 minutes.

For high-altitude operation scenarios, an intelligent hoisting monitoring system is equipped to real-time track hoisting angles and stress conditions, ensuring safety. Take a 10,000 ㎡ steel structure workshop as an example: traditional installation takes 60–90 days, while modular technology cuts the time down to 30–45 days, improving installation efficiency by 50%.

Ⅲ. Value Empowerment: Creating Long-term Returns for Customers

Cost Empowerment: Whole-life Cycle Cost Optimization

Although the initial construction cost of steel structures is 5%–10% higher than that of concrete structures, when viewed over the entire 50-year life cycle, their maintenance cost is only 1/4 of that of concrete structures. Moreover, 100% of the steel can be recycled after demolition (with the recycling value reaching 70% of the original material cost), resulting in a 15%–20% reduction in the overall life-cycle cost. Take a 10,000 ㎡ workshop as an example: the total life-cycle cost of a steel structure solution can save 800,000–1,200,000 yuan compared with a concrete structure solution.

Efficiency Empowerment: Accelerating Project Implementation and Commissioning

Combining factory prefabrication with rapid on-site installation significantly shortens the project cycle. For industrial workshops, the time from design to commissioning is only 3–6 months, over 50% shorter than that of traditional concrete structures; for civil buildings, the time from groundbreaking to delivery is just 6–12 months. This helps customers quickly seize market opportunities. For instance, manufacturing clients can put production into operation 3–6 months in advance, generating an additional output value of tens of millions of yuan.

Environmental Empowerment: Helping Customers Achieve Dual Carbon Goals

The energy consumption during the production of steel structures is only half that of concrete structures, and it can reduce deforestation (each 10,000 ㎡ steel structure building can cut wood usage by more than 500 cubic meters). There is no construction waste pollution after the building is demolished. Choosing a steel structure solution can help customers reduce carbon emissions (each 10,000 ㎡ building can reduce carbon emissions by approximately 200 tons), facilitate the improvement of enterprises' ESG (Environmental, Social, and Governance) ratings, and enhance brand competitiveness.
