Selection and Application of Structural Steel Materials for Aircraft Maintenance Hangars​

-
图片
 Aircraft maintenance hangars , as the core facilities for aircraft inspection and repair operations, must endure long-term exposure to large-span loads, extreme weather conditions, and complex operational environments. Consequently, stringent requirements are imposed on the strength, weather resistance, and stability of the structural steel materials employed. The judicious selection of suitable steel structural materials not only ensures the hangar's safe operation but also reduces construction and maintenance costs. Based on the functional requirements of different structural components within the hangar, commonly used steel structural materials can be categorised into three main types, each playing a critical role in hangar construction. I. Primary Load-Bearing Structure: The Core Material Supporting the Hangar's ‘Skeleton’ The primary load-bearing structure forms the hangar's ‘skeleton’, bearing the hangar's own weight, aircraft parking loads, and external forces s...

Advantages of steel structure?

-

 With the rapid development of modern construction technology, steel structure building, as an efficient, environmentally friendly and safe form of construction, is becoming the mainstream trend of future construction with its unique advantages.

space frame


1. Environmentally friendly and efficient

The production and transportation of traditional building materials will produce a large amount of carbon dioxide emissions, while most of the materials of steel structure buildings can be recycled, reducing the waste of resources and effectively protecting the environment.

2. Superior Strength

Steel has extremely high strength and rigidity, compared with concrete structure, the components of steel structure can be smaller under the same bearing force, thus enhancing the use of space and design flexibility of the building.

3. Safety and Reliability 

After precise calculation and engineering design, steel structure buildings can show excellent pressure and shock resistance in the face of natural disasters such as earthquakes and windstorms, providing a safer living environment for residents.

4. Fast construction speed

Compared with traditional buildings, the production process of steel structure is more advanced and the construction speed is faster, which greatly saves the construction cycle and saves costs for the owners.

5. High space utilisation

The lightweight nature of steel structure makes it possible to support buildings with larger spans and maximize the use of building space, which meets the diverse needs of modern people for living and office space.

6. Sustainable development

As the society attaches importance to sustainable development, steel structure building is becoming one of the representatives of green building. Not only does it have a shorter construction period, but it also allows for the recycling of materials, minimising the impact on the environment. 

As an industry leader, we are committed to providing you with the highest quality steel structure solutions. Whether it's a residential, commercial or industrial project, we have the experience and professional team to create a safe, efficient and environmentally friendly steel building tailored to your needs.

What is a coal bunker?

-

Coal bunker , is a structure used for storing coal. Coal bunkers play an important role in thermal power plants, coal mines and coal marshalling stations. Depending on the specific application scenario and design, there are various types of coal bunkers, such as circular coal bunkers, square coal bunkers and open coal yards. Safety Management of coal bunkers Preventing spontaneous combustion of coal: Since coal itself contains certain moisture and volatile substances, long-term exposure to the air may lead to spontaneous combustion, so the safe management of coal bunkers is of great significance in preventing spontaneous combustion of coal. Ensure the quality of coal: coal in the coal bunker usually needs to be stored for a long time, if not managed properly, it may lead to the decline in the quality of coal, such as sulphurisation, weathering and other phenomena, so it is necessary to ensure the quality of coal by strengthening the safety management of the coal bunker. Improve the eco...

What is the difference between a single-layer reticulated shell and a double-layerreticulated shell?

图片
  The differences between single-layer reticulated shells and double-layer reticulated shells are as follows: Structural Configuration   Single-layer reticulated shell: Composed of a single layer of members, with the members directly connected to form a grid structure . The node configuration is relatively simple, typically employing rigid connections that allow the members to bear not only axial forces but also bending moments and shear forces.   Double-layer reticulated shell: Consists of upper and lower parallel layers of members connected by web members, forming a truss-like structural system. The nodes are generally hinged, and the members primarily bear axial forces. Its configuration is relatively complex, requiring more members and nodes to ensure structural stability and load-bearing capacity. Structure Single-layer mesh shell: composed of one layer of rods, the rods are directly connected to form a mesh structure, the node structure is relatively simple, usually...

What are the differences between bolted ball grids and welded ball grids?

-
图片
 There are a number of differences between bolted ball grids and welded ball grids in terms of fabrication, construction and design. The following are specific comparisons: 1. Manufacturing process: The manufacturing of bolted ball net frame is mainly carried out in the factory, using mechanical shot blasting to remove rust, and then spraying paint, plastic spraying or zinc spraying treatment to enhance corrosion resistance.  The steel pipe and welded seam of welded ball mesh frame can only be descaled manually on site, and then paint or fireproof coating is brushed. For the welded part, it needs to be descaled and brushed at a stage to maintain, which increases the cost of later use and affects the safety of the structure. 2. Construction process: 70% of the workload of bolted ball grid frame is prefabricated in the factory, 30% of the workload is installed at the site, only a wrench is needed to tighten the bolts at the site, which is easy and fast, and can be constructed ...
