Space Frame Steel Roofs: A More Cost-Effective Choice for Large-Span Buildings Than Concrete

-

 When planning large-span buildings—from industrial warehouses and exhibition halls to transportation hubs—selecting the right roof system is not just a structural decision, but a financial one that impacts budgets for decades. Concrete has long been a traditional option for such projects, valued for its familiarity rather than its long-term efficiency. However, space frame steel roofs have emerged as a superior alternative, delivering cost savings that extend far beyond upfront expenses and align with the practical needs of modern large-span construction. The myth that concrete is the cheaper choice often stems from a narrow focus on material costs alone. While concrete may have a lower price per ton at first glance, this ignores the full scope of expenses that come with concrete roof installation. Space frame steel roofs, by contrast, are engineered for efficiency at every stage, starting with their lightweight and modular design. Unlike concrete roofs, which require massive, rei...

The chessboard -shaped quadrilateral mesh grid has good overall and stability, flexible plane layout, the upper string rod of the structure is short and the lower chord is long. The rods of the exchange are relatively small, the roof structure is simple, and the construction is convenient. The emergence of a large number of new materials, new processes, and new technologies in modern times fully reflects the advancedness, economy and rationality of the grid structure. In the future, the chessboard -shaped quadrilateral cone network shelf will be used more and more many.

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?

  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...

 It is widely used in modernist architecture. Steel structure installation is mainly carried out by electric welding welding and bolts. Because the steel frame structure is compact and practical, it brings great convenience to engineering construction. In order to promote the sustainable development concept of steel frame structure in the construction engineering industry, it is necessary to carry out an in-depth analysis of the construction stage of steel structure, especially the node design, to ensure reliability.       Steel plate materials are widely used in modernist buildings because of their extreme seismic performance, plasticity and reliability. Jiangsu steel structure project construction is to be processed with bolts or steel to make the building structure. Accompanied by the improvement of living standards and the rapid development of the construction industry, the requirements for steel frame structure are rigorous. As a result, the design of steel fra...
