Steel structure grid processing has good-scale private steel structure grid processing enterprises, as well as many extensive operation grid processing plants, intensive operation grid processing plants, and affiliated operating companies, etc. According to the situation of my country's steel structure market According to the analysis, it can be clearly seen that steel structure enterprises are choosing favorable conditions for development, and under the premise of sharing market resources, they will seize market share with their respective advantages. However, steel structure construction is still in the development stage in our country at present, and it accounts for a small proportion of the total construction volume. For some landmark projects, foreign companies do everything from conceptual design to structural design. Most domestic steel structure grid companies only process and manufacture.

In recent years, large-scale projects have repeatedly won bids by some foreign companies, which should arouse people’s reflection and attention. In our engineering practice, a number of novel buildings are being built with high cost and high consumables, but it goes against the low-carbon, lightweight, and The original intention of environmental protection. Among them, the most famous one is the bird's nest. From the bird's-eye view, it looks like a bird's nest, "returning to nature" and "perfect innocence". From the night view, it is crystal clear and overflowing with light, so it has won the favor of many experts and leaders. Is its beauty really as touching as it is rendered on paper? In fact, when spectators enter the bird’s nest to watch the game, what they see may not be the bird’s-eye view, but the huge oblique beams and steel columns. Some engineers even pointed out that the unreasonable load-bearing structure of the bird’s nest has cost us a lot. Human, material and financial resources. By analyzing representative projects abroad, we can find:
One. Foreign design projects are mostly major projects concentrated in the capital and coastal cities. They have sufficient financial resources and do not care about economic benefits, while domestic design projects are mostly fixed investment regional projects, and their economy is still an important factor in the selection of plans. .
two. The steel structure grid structure system designed abroad mostly adopts the plane simply supported truss which consumes a lot of steel, and the domestic adopts more advanced space grids and reticulated shells. Therefore, the steel consumption of foreign designs is generally higher than 100kg/, and some It can be as high as several hundred kg/, and domestic designs are generally less than 100kg/, and some can be as low as 20-30100kg/.
three. Foreign design models are novel, but the load-bearing system and structure are traditional and cumbersome, increasing the weight and consumables and increasing the amount of labor.
Therefore, my country's steel structure grid processing enterprises must improve their determination to develop low-carbon and cost-effective steel structures. Even if the company is just trying to survive for its own brand. We should get an enlightenment that all companies are willing to responsibly enlarge and strengthen their corporate culture. Then, China's steel grid processing will certainly achieve the original intention of low-carbon construction.
