Canglong steel structure technology helps prefab hangar

Under the dual drive of global manufacturing upgrading and logistics efficiency revolution, prefab hangar, as key infrastructure in aviation, high-end equipment manufacturing, new energy and other fields, are facing explosive demand. From European aviation maintenance bases to Southeast Asian new energy equipment warehousing centers, from North American cross-border e-commerce logistics parks to Middle Eastern oil equipment transfer stations, prefabricated hangars have become a new favorite in industrial infrastructure construction due to their fast deployment, flexible adaptation, and controllable costs.

However, in complex environments that span across climatic zones and geological conditions, traditional hangar construction faces three core difficulties: uncontrollable project timelines, cost overruns, and poor adaptability. The redefinition of prefabricated hangar construction logic through steel structure technology has truly ushered in the golden age of industrial construction in the global industrial warehousing field.

Ⅰ. Three major challenges in the construction of prefab hangar

The essence of prefabricated hangar is the industrial replication of large industrial spaces, but the traditional construction model has long been plagued by three major challenges:

1. Long construction period

Traditional hangars often adopt the construction method of concrete frames and color steel plate roofs. From foundation treatment, main body pouring to roof installation, a hangar with a single building area of 5000 square meters takes 6-8 months. However, global manufacturing orders fluctuate frequently, and companies often face the embarrassment of falling behind after the completion of hangar construction. For example, a Southeast Asian new energy battery factory was forced to lease a temporary warehouse for transition due to the early production of its production line, resulting in an additional 30% increase in operating costs.

2. High cost

Concrete structures are sensitive to geological conditions, and additional pile driving reinforcement is required for soft soil foundations. The cost per square meter is 20% -30% higher than that of steel structures. If encountering areas with frequent typhoons (such as the Gulf of Mexico and the Indian Ocean coast), additional reinforcement of roofs and walls is required, further increasing costs. More importantly, once the concrete structure is designed and finalized, it is difficult to expand or transform in the later stage. When facing the demand for upgrading enterprise production capacity, it often faces the dilemma of "dismantling leads to waste, leaving leads to low efficiency".

3. Poor adaptability

There are huge differences in global climate and geological conditions. The Middle East desert region needs to cope with high temperatures of 60 ℃ and sandstorm erosion, the Nordic cold region needs to resist low temperatures of -40 ℃ and freeze-thaw cycles, and coastal areas need to resist salt spray corrosion and typhoon impact. The localized customization model of traditional concrete hangars requires design and construction teams to repeatedly adjust materials and processes, resulting in cost and schedule fluctuations of over 50% when replicating across regions.

Ⅱ. Empowering Prefab Hangar with Steel Structure

When the traditional model fell into a dilemma, Canglong Group's steel structure prefab hangar solution redefined the construction standards of global industrial warehousing with its three core advantages of industrialization, modularization, and customization.

Advantage 1: Industrial intelligent manufacturing, reducing construction period by 60%

Canglong Group adopts a full process industrialization model of design factory site: firstly, BIM (Building Information Modeling) technology is used to simulate the entire life cycle of the hangar, accurately calculating parameters such as load, wind vibration, temperature stress, etc. Subsequently, standardized production of steel columns, beams, purlins, color steel plates and other components will be completed in the factory, with an error controlled within ± 2mm. Finally, through the on-site assembly process of "bolt connection+quick locking", a single 5000 ㎡ hangar can be delivered in just 45-60 days. Taking a certain aviation maintenance hangar project in Africa as an example, the Canglong team completed the entire construction process from foundation to roof in just 45 days, which is 70% faster than the traditional mode and perfectly matches the urgent needs of customers to build and put into operation at the same time.

Advantage 2: Modular design, reducing cost by 30%+

The core advantage of steel structure lies in "lightweight+scalable": Canglong uses Q235/Q355 high-strength steel (yield strength ≥ 235MPa/355MPa), combined with truss beam column structure, to control the steel consumption per unit area within 80-100kg/㎡ (lighter than traditional concrete structure by more than 40%), and reduce the foundation cost by 50%. At the same time, the main structure of the hangar adopts a modular design with a main frame and detachable enclosure. If there is a need to expand the area or adjust the floor height in the later stage, it can be completed by adding or removing steel truss modules without damaging the original structure, truly achieving "one construction, multiple upgrades". A certain European new energy equipment storage center project adopted this plan, reducing the initial construction cost by 28% compared to the budget. Later, due to the doubling of production capacity, module assembly was completed in just 15 days, saving more than 60% of time and cost.

Advantage 3: Customized protection, allowing global adaptation without blind spots

Canglong Group has developed a climate adaptive steel structure protection system for extreme environments in different regions:

High salt spray areas (such as the Middle East and Southeast Asia): Adopting a dual anti-corrosion process of hot-dip galvanizing (zinc layer thickness ≥ 85 μ m) and fluorocarbon spraying, the corrosion resistance life of steel is extended to more than 30 years.

Strong earthquake zones (such as Japan and Chile): Through the design of "flexible nodes+dampers", the steel frame can absorb more than 80% of earthquake energy, meeting the local seismic fortification intensity requirements.

Cold regions (such as Russia and Canada): Double layer color steel plates with 100mm polyurethane insulation layer are used, and the roof heat transfer coefficient is ≤ 0.35W/(㎡· K), ensuring stable internal temperature in an environment of -40 ℃.

High temperature and high humidity areas (such as India and Brazil): The surface of steel components is coated with weather resistant steel coating, and with the design of ventilated roofs, the internal humidity is controlled below 60% to avoid equipment corrosion.

Ⅲ. Canglong Global Practice: From "Chinese Standards" to "World Solutions"

With a deep breakthrough in steel structure technology, Canglong Group has landed over 50 prefab hangar projects in 20+countries worldwide, verifying the global competitiveness of "China Construction" through practical cases

European Aviation Maintenance Base (Germany): In response to strict local environmental regulations (carbon emission limits), Canglong adopts a "photovoltaic integrated steel structure roof" and uses BIPV (building photovoltaic integration) technology to lay monocrystalline silicon photovoltaic panels on the top of the hangar. The annual power generation can reach 800000 kWh, meeting 30% of the daily electricity demand of the hangar and obtaining T Ü V certification from Germany.

Southeast Asia New Energy Equipment Storage Center (Vietnam): Faced with frequent typhoons (12 typhoons per year) and salt spray corrosion, the Canglong steel frame adopts a combination structure of "round pipe columns+H-shaped steel beams", with a wind resistance level of 14. Combined with hot-dip galvanizing anti-corrosion technology, the steel structure has no rust marks after 3 years of project delivery, and the customer evaluation is "more durable than local concrete hangars for 10 years".

North American Cross border E-commerce Logistics Park (Texas, USA): In response to extreme weather conditions (winter blizzards, summer high temperatures), Canglong has designed a large-span column free steel structure (single span 48m), combined with an adjustable temperature color steel plate roof (reflecting 90% of solar radiation in summer and adjustable insulation layer thickness in winter), to achieve a constant temperature storage environment of "warm in winter and cool in summer", helping customers reduce energy consumption costs by 20%.

Ⅳ. Conclusion

When rapid deployment, flexible adaptation, and green low-carbon become the core demands of global industrial infrastructure, Canglong Group's steel structure technology is providing solutions for prefab hangar construction with three core capabilities: "industrial intelligent manufacturing+modular design+climate adaptability protection". From Africa to North America, from deserts to cold regions, Canglong has proven with benchmark projects that steel structures are not only construction tools, but also the core engine for global industrial space reconstruction.

In the future, with the deepening of the "the Belt and Road" initiative and the upgrading of the global manufacturing industry, Canglong Group will continue to take technological innovation as the wing to promote the prefabrication hangar from "regional customization" to "global standards" and output more hard core solutions for China's high-end manufacturing.
