1. Steel structure stadium: 4 game-changing advantages over traditional construction
As a typical representative of building industrialization, steel structure redefines sports stadiums with industrial aesthetics and functional innovation. This spatial revolution triggered by steel is making “large span, short construction period, and low energy consumption” possible.
1.1 Large space without columns, reshaping the viewing experience
Large-span space trusses (single span up to 180 meters) or grid structures (such as a three-dimensional spider web layout) are used in Steel structure building to eliminate column obstruction and increase the audience’s field of vision by 50%. This technology is the same as the largest hangar in Asia (column-free span of 404 meters) and can easily cover the main stand of a stadium that can accommodate 100,000 people. In terms of cost, the grid structure costs $300-500 USD/㎡. Compared with the concrete solution, it has both technological advancement and economic efficiency, and can save 20%-30% of the space utilization cost.
1.2 Fast construction, seize the commercial opportunity
Modular prefabrication: 95% of the components are prefabricated in the factory, bolted on site, and the main construction of a 20,000㎡ stadium takes only 90 days (150 days shorter than traditional processes). Modular interfaces are reserved, and commercial floors, VIP boxes, or temporary parking lots can be quickly added after the game, and the renovation cycle only takes 3 months.
1.3 Green and low-carbon, responding to policy dividends
Environmental protection data: Steel is 100% recyclable, construction waste is reduced by 90%, carbon emissions are 57% lower than concrete, and it is easy to pass the green building certification. With a photovoltaic integrated roof (annual power generation covers 30% of electricity consumption) + a three-dimensional ventilation system, energy consumption during operation is reduced by 18%.
1.4 Intelligent and safe, guarding the event without any mistakes.
GB, EN, and AISC design specifications are adopted, and Q355B S355JR A572 SM490A high-strength steel is used. Q355B S355JR A572 SM490A high-strength steel is used, and it has passed the seismic test.
2. Four major steel structure solutions, adapted to different scene requirements
In the era of customization of “one venue, one policy”, steel structures solve scenario-based problems with a combination of multiple technologies. From international events with tens of thousands of people to community-level training bases, the modular solutions of XTD Steel Structure are achieving “precise matching of needs and dynamic response to the market”.
| Scene Type | Recommended Solution | Core Performance | Owner benefits |
| Large international event venues | 180m long span space truss + grid | It can accommodate 80,000 to 100,000 spectators, with full coverage of pillar-less vision, and is equipped with VIP boxes and a media center | Undertake top events and enhance the city’s business card effect |
| Professional training base | Standardized portal frame + flexible partition | Single span is 30-50 meters, which can quickly divide the training area, locker room, and physical therapy room, saving 30% of steel consumption | Low-cost and fast implementation, supporting later functional adjustments |
| Multi-purpose commercial stadium | Steel structure multi-storey complex building (with commercial floor) | Vertical space utilization increased by 300%, integrated catering, retail, and parking, and annual commercial revenue increased by 200% | Dual-mode operation: watching games during the match + daily business |
| Temporary event venues | Light steel structure + quick disassembly and assembly system | Full process delivery within 45 days, removable and relocatable, cost of a single module: $80,000 | Respond to short-term event needs and reduce idle risks |
3. Truss structures: Unlocking new possibilities for open-air venues
Based on the technical advantages of a large span, high load-bearing capacity, and flexible layout, the truss system of XTD steel structure is extending from sports stadiums to more open space scenes.
3.1 Large exhibition halls/convention, and exhibition centers
Adaptation logic: A large column-free space is required to meet the free layout of exhibits. The single span requirement is generally 80-120 meters. The traditional concrete solution requires dense columns (affecting the exhibition experience), while the steel structure truss can achieve a clear span of 140 meters (similar to the same technology of the Shanghai National Convention and Exhibition Center), and the exhibition efficiency is increased by 40%.
3.2. Super-large industrial plants/logistics warehouses
Efficiency upgrade: Heavy industrial plants need to carry overweight equipment (such as aircraft maintenance hangars with loads ≥5t/㎡). The truss structure can achieve a single span of 160 meters and a load capacity increase of 20% through H-shaped steel reinforcement design, saving 15% of steel compared to the concrete solution. The automated storage center requires unobstructed high-altitude operations. The steel structure truss combined with the intelligent skylight can optimize the movement line of the storage robot, and the space utilization rate reaches 92% (the traditional solution is only 75%).
3.3. Acoustic optimization of cultural and art venues (theaters/concert halls)
The truss structure is lightweight, which is convenient for hanging professional acoustic ceilings (such as the same structure as the National Grand Theater). The reverberation time can be accurately controlled at 1.2-1.8 seconds, meeting the needs of different performances such as symphonies and operas. Free-form trusses (such as wave-shaped and dome-shaped) support the creative implementation of architectural masters. A provincial theater uses a hyperbolic truss system with a construction error controlled at ±3mm, becoming a cultural landmark of the city.
4. Comparison with traditional concrete solutions:
In recent years, steel structures have accounted for 68% of newly built sports venues, an increase of 42 percentage points from five years ago. When efficiency and sustainability become hard indicators, the rise of steel structures is rewriting the rules of the industry.
| Core indicators | Steel structure scheme | Traditional concrete solution | Owner Savings |
| Construction period | 90 days (20,000 m2) | 240 days | 150 days (operation started half a year in advance) |
| Renovation cost | Local module adjustment reduces costs by 60% | Need to be demolished and rebuilt, high cost | Later expansion saves more than one million US dollars |
| Life cycle cost | The overall cost is 15%-20% lower | Post-maintenance accounts for more than 30% | Save operating costs |
| Recycling value | Steel recycling value reaches 30% of the construction cost | Concrete has almost no recycling value | Can be recycled after retirement |
5. FAQs
Q 1. How can a steel structure stadium ensure earthquake resistance and wind resistance?
A: When designing, engineers will carefully calculate the load that the building will bear based on the earthquake resistance requirements of the area where the stadium is located (such as the local requirement of 8-degree fortification) and wind conditions (such as the basic wind pressure of 0.55kN/m²). In terms of structural design, the main body of the stadium generally adopts a space truss, grid, or tube truss system, and the entire building is made stronger by designing the nodes as rigid or hinged. When selecting materials, the components will use Q355B S355JR A572 SM490A grade steel, which has high strength and good quality, so that each part is firmly connected together.
Before construction, simulate the response of the stadium in extreme conditions such as earthquakes and strong winds to see whether the displacement and stress of the building are within the specified safety range when frequent earthquakes, rare earthquakes, or once-in-a-century typhoons strike.
| Comparison Dimensions | Modern construction methods of steel structure stadiums | Traditional construction method |
| Design basis | Strictly follow the steel structure design standards, combine the seismic fortification intensity and basic wind pressure to accurately calculate the load | Design is mostly based on experience, and the load calculation accuracy is low |
| Structural system | Adopt a space truss, grid, or tube truss system, and improve the overall rigidity through node rigid connection or hinged design | Most of them are traditional structures such as brick-concrete and concrete frames, with relatively weak rigidity and stability. |
| Material selection | The components are made of Q355B S355JR A572 SM490A grade steel, and important nodes are made of cast steel or intersecting line welding technology. | Commonly used materials such as bricks and concrete have poor strength and toughness |
| Process Technology | Adopt EN and AISC design specifications, conduct finite element analysis before construction, simulate extreme load conditions, and set up temperature expansion joints, shock absorbers, and other structural measures | Less use of simulation analysis technology, insufficient ability to cope with environmental effects |
| Performance Guarantee | The triple system ensures earthquake and wind resistance, and can withstand extreme situations such as frequent earthquakes, rare earthquakes, and once-in-a-century typhoons. | Weak earthquake and wind resistance, low safety in the face of extreme disasters |
Q2. Is the cost of a steel structure stadium really more expensive than a concrete stadium? In the long run, which structure is more cost-effective?
A: The components of the steel structure can be produced in advance in the factory and transported to the site for assembly, like building blocks. The construction speed is 30% to 50% faster than that of traditional concrete structures. The construction period is shortened, and labor costs and management fees can naturally be saved a lot. Moreover, steel is much lighter than concrete, only half or even one-third of the weight of concrete, which means that the foundation is under less pressure and the cost of laying the foundation can also be saved. The steel structure stadium also has a “hidden advantage”: its steel recycling rate can exceed 90%. After the stadium is retired, these steel can be dismantled and sold for money. The waste generated after the demolition of the concrete structure is not only of little value, but also costs a lot of money to deal with. In comparison, the environmental protection and economic benefits of the steel structure are more obvious.
Q3. Can steel structures be used to build large-span stadiums? How can we ensure that the sound in the stadium is clear and the light is bright enough?
A: Steel structures are particularly suitable for large-span buildings. Designs such as tubular trusses, beam string structures, and cable-membrane structures can easily build a space with a span of 80 to 200 meters. For example, the span of the roof of some stadiums reaches 180 meters, and there are no pillars in the middle to block the view, so the audience can see the game more clearly, and the venue is more spacious to use. In terms of lighting, light strips are mined on the roof, laminated glass or sun panels are used, and then equipped with glass curtain walls on the side, plus an intelligent lighting system, it can automatically switch between natural light and artificial light according to the weather and actual needs, which is both energy-saving and practical. Moreover, the connection points of the steel structure are designed to be very flexible, and it is very convenient to install large LED screens and audio equipment in the future. Whether it is a competition or a performance, it can be easily handled.
| Comparison Dimensions | Traditional building methods | Steel structure stadium |
| Large span implementation method | Concrete beam-column structures are often used. When the span is large, additional columns need to be added, which affects the integrity of the internal space. | Through the use of tube trusses, beam string, cable membrane structures, etc., it is easy to achieve a span of 80-200 meters, with no columns blocking the interior and a wide field of vision. |
| Acoustic Treatment | Relying on thick solid walls, the sound absorption effect is limited and the reverberation time is difficult to accurately control | Use space sound absorbers (such as perforated aluminum plates + sound-absorbing cotton) and wall sound-absorbing materials (such as polyester fiber sound-absorbing panels) to accurately control the reverberation time at 2.5-3.5 seconds, effectively avoiding echo interference |
| Lighting design | Most of them are fixed windows or skylights, which make it difficult to use natural light and consume a lot of energy for artificial lighting. | The top lighting strip (such as laminated glass or sunlight panel) combined with the side curtain wall and the intelligent lighting control system can achieve seamless switching between natural light and artificial light, reducing energy consumption. |
| Flexibility for later transformation | The structure is fixed, and renovation requires a lot of demolition and reconstruction, which is costly and time-consuming. | The flexible node design of the steel structure facilitates the installation and modification of later equipment (such as LED display screens and sound reinforcement systems) to meet the needs of multi-functional events and performances. |
Q4. How long does it take to build a steel structure stadium? How to ensure it is completed on time?
A: Generally speaking, it takes 1 to 2 years to build a steel structure stadium, depending on the size and complexity of the stadium. The entire construction process can be divided into three stages:
Foundation stage (3-6 months): In this stage, the underground pile foundation and independent column foundation must be built first, and the underground water pipes, wires, and other pipelines must be buried. While the workers are digging and piling, the design team can simultaneously carry out detailed design of the steel structure and start construction on both sides at the same time to save time.
Steel structure stage (5-8 months): First, steel beams, steel columns, and other components are produced in the factory, and then transported to the site for assembly. There are two common construction methods: one is to assemble the steel structure as a whole on the ground, and then slowly lift it to a high place with hydraulic equipment; the other is to divide the steel structure into small pieces and hoist and splice them one by one. Both methods can reduce the danger of high-altitude operations and make construction safer.
Roofing and decoration stage (4-6 months): install metal roof, glass curtain wall, then carry out interior decoration, and finally debug lighting, air conditioning, audio, and other equipment. In order to avoid construction delays, the construction team will use BIM technology to see the production progress of each component and whether there are deviations in on-site installation in real time, and can also plan the connection of each process in advance. In addition, for special weather such as the rainy season and winter, special construction plans will be formulated in advance. In the past, there was a stadium that could accommodate 30,000 people. The main structure was completed 45 days in advance by arranging the process reasonably.
Q5. Can personalized shapes be achieved according to architectural design drawings?
A: We have full-process service capabilities, and all personalized designs can become a reality.
Complex shapes are easily made: Using BIM and parametric design technology, whether it is a hyperbolic roof, a circular dome, or a wavy appearance, it can be made (like the curved structure of the Beijing Bird’s Nest), with super high construction accuracy and an error of no more than 3 mm.
Super flexible material selection: various steel materials can be matched at will, and H-shaped steel, box beams, and round tube trusses can be used as you want. Whether it is a 50-meter-long, column-free grandstand or a transparent exterior with 80% of the area covered by glass curtain walls, both can meet the design requirements.
Actual case: In a stadium project, the steel truss roof adopts a ribbon design, which is matched with an LED light show at night, becoming a beautiful scenery in the city. And compared with traditional concrete construction, the construction period is shortened by a full 60 days.
| Comparison Dimensions | Traditional construction method | Customized capability solutions for the entire industry chain |
| Modeling realization | Complex surface modeling is difficult to achieve, relies on templates, and has large errors | Relying on BIM and parametric design, complex shapes such as hyperbolic surfaces and domes can be completed, and the construction error is controlled within ±3mm |
| Material Application | The choice of materials and components is limited, making it difficult to balance large cantilevers and transparent facades | The combination of H-shaped steel, box beams, and other multiple components supports a 50-meter column-free cantilever and a transparent design with 80% glass curtain wall |
| Construction period | The concrete structure construction process is complicated, and the construction period is long | Taking a popular stadium as an example, the construction period was shortened by 60 days compared with the concrete solution. |
| Creative implementation | Design and construction are out of touch, and creativity is easily reduced | The whole industry chain collaborates to ensure full support from design to construction, such as the “ribbon-style” steel truss roof combined with LED light show, which was successfully implemented |
