How powerful is the processing of lightweight grid steel structures?

How powerful is lightweight grid processing? Below, Lianyue editor will first introduce the characteristics of the processing of lightweight steel structure grids:

1. Lightweight. Its load-bearing structure adopts lightweight welded H-shaped steel and cold-formed thin-walled steel. This type of steel section shape can be designed according to the actual stress situation and usage characteristics. Compared to ordinary I-beams, channel steels, and angle steels, the stress is reasonable, the section utilization coefficient is high, the unit weight is light, and steel can be saved by 20-50%. The colored profiled steel plate for roof and wall enclosure structures is only 8-15kg per square meter, which is close to the steel consumption of reinforced concrete structures under the same conditions, and can save a lot of wood Cement and other building materials reduce the weight of the structure to 70-80% of that of ordinary steel structures, which not only reduces the overall cost but also greatly reduces the material consumption and workload of basic engineering.

2. Short construction period. All components in lightweight steel structures can be manufactured by the factory and assembled on-site. It only takes 1-2 months for generally small-scale industrial factories, while it takes about 10-12 months for reinforced concrete structures.

3. Good economic effect. Due to the fact that the components of this structure are all produced in industrial quantities, their quality is easy to control. Adopting such a building structural system is much cheaper and more cost-effective than concrete structures.

4. Fast supply and convenient installation. The industrial production and light weight of materials determine the advantage of rapid supply. Due to the use of bolts, self tapping screws, and other connections, small on-site welding workload, no wet operations, no need for formwork support, no maintenance period, and no impact on winter construction period, based on past construction experience, the construction period can be shortened by at least half compared to concrete structures.

5. Steel has high strength, good plasticity and toughness. The steel used in lightweight steel structures has high strength, good plasticity and toughness, so it can ensure that the structure will not undergo sudden damage during use, is not easily brittle when subjected to impact, and has good performance in bearing dynamic loads, high reliability, and seismic resistance. Grid structures are suitable for earthquake zones and major buildings.

6. Good lighting. Industrial factories generally need to make better use of natural light, and lightweight steel structure systems heavily use daylighting strips, which not only meet the requirements for light in production but also reduce costs.

7. Good seismic performance. Due to its flexible structure and light weight, steel structures can effectively reduce earthquake response and disaster impact, which is extremely beneficial for earthquake resistance. The wall keel forms a very sturdy rib structure system after sealing the structural board and gypsum board, providing stronger seismic resistance and resistance to horizontal loads. Light steel buildings can withstand earthquakes of magnitude 8.

8. Beautiful appearance, lively rhythm, large internal space, and easier separation of space compared to ordinary structures, making it convenient for expansion and renovation, and allowing for flexible layout of various industrial pipelines.

9. Lightweight steel structures are easy to install and easy to remove. As mentioned above, using lightweight steel structures, especially lightweight portal frame houses, is lower in cost than reinforced concrete structures, and the comprehensive economic benefits of early production and benefits are higher.
