Ten Advantages of Structural Plant Buildings: 1. Earthquake Resistance: The roofs of low-rise villas are mostly sloped roofs. Therefore, the roof structure mainly adopts a triangular truss system made of cold-bent steel components. After the structural panels and gypsum boards are sealed, a very strong "plate-rib structural system" is formed. This structural system has stronger earthquake resistance and resistance to horizontal loads and is suitable for areas with seismic intensity of 8 degrees or more. 2. Wind Resistance: Steel structure buildings are light in weight, high in strength, good in overall rigidity, and strong in deformation ability. The self-weight of the building is only one-fifth of that of a brick-concrete structure, and it can withstand every

While China had remarkable achievements in iron structures in its early history, it remained stagnant in iron building technology for over two millennia due to the constraints of the feudal system and the lack of scientific development. It wasn't until the late 19th century that China began adopting modern steel structures. Following the establishment of the People's Republic of China, the application of steel structures significantly advanced, surpassing the past in both quantity and quality. High levels of expertise have been achieved in design, manufacturing, and installation, mastering the design and construction techniques for various complex buildings. Numerous large-scale and structurally complex steel structures, such as factory buildings and large-span steel structures, have been constructed throughout the country.

In recent years, steel structure buildings, as a type of green, circular, and low-carbon building that coexists harmoniously with nature, have been rapidly rising with the acceleration of China's urbanization process. Industry insiders believe this will create a huge market space for steel used in steel structures, while also placing new and higher demands on the steel used in steel structures. At present, problems such as the limited variety and poor quality stability of steel used in steel structures in China urgently need to be solved, and domestic steel companies also need to strengthen their attention to steel used in steel structures. Developing new steel varieties to meet the market demand for steel used in steel structures is a long and arduous task for steel enterprises. "Beautiful China" calls for green buildings. In terms of carbon emissions...

Shenyang starts rectifying fire safety issues in color steel structures. Li Guoxiao, the chief of the Shenyang Municipal Public Security Fire Brigade, stated that there are currently 255 color steel structure worker dormitories on construction sites across the city, of which 170 are substandard. Multiple fires have occurred in such color steel structure worker dormitories this year alone. Therefore, Shenyang requires construction units to complete the rectification tasks on time, according to standards and requirements, ensuring quality and quantity. Those who fail to rectify within the deadline will be sealed up according to law to ensure fire safety on construction sites.

Reports indicate weak demand in South Korea's color-coated steel sheet and steel pipe market. Currently, steel mills are pricing at KRW 1.15 million/ton, while the market circulation price is slightly above KRW 900,000/ton, representing a 20% discount. Considering the price of galvanized steel sheet at KRW 890,000/ton, color-coated steel sheets are essentially unprofitable. Steel pipes are no exception, with high discount rates currently applied; around 15% for fluid pipes and around 20% for structural pipes. Despite this, the sluggish sales situation remains unchanged. It is understood that the current capacity utilization rate for color-coated steel sheets and steel pipes in South Korea is below 80%, severely impacting normal production due to high inventory levels. Furthermore, the two industries...

A press conference on the implementation of the China Environmental Mark Low-Carbon Cement Standard and the awarding ceremony for the first batch of pilot enterprises certified for China Environmental Mark Low-Carbon Cement Products was recently held in Beijing. Fourteen cement companies, including China Materials Zhuzhou Cement Co., Ltd., China Materials Changde Cement Co., Ltd., China National Building Material Group Co., Ltd. Changshan Southern Cement Co., Ltd., and Chongqing Lafarge Riandiwei Cement Co., Ltd., received the title of the first batch of pilot enterprises certified for China Environmental Mark Low-Carbon Cement Products. In order to promote further development of the cement industry towards low-carbon, environmentally friendly, and sustainable development, and to reduce

With the rapid development of electronic technology, especially microelectronics, computer technology, and ultrasonic transducer technology, ultrasonic phased array and TOFD detection technologies have emerged in recent years and become the trend in ultrasonic flaw detection. Ultrasonic phased array integrates multiple elements (e.g., 32, 64, 128) into one transducer. The excitation time of each element can be adjusted individually. By controlling parameters such as the sound beam axis and focus, an array of transducer elements is formed to achieve a full cross-sectional scan of the weld. TOFD (Time Of Flight Diffraction) is a technique that relies on signals diffracted from internal structures (mainly...

Coated steel sheets are lightweight, aesthetically pleasing, and have good corrosion resistance. They can also be directly processed, providing a new type of raw material for the construction, shipbuilding, vehicle manufacturing, furniture, and electrical industries. They offer benefits such as replacing wood with steel, efficient construction, energy savings, and pollution prevention. Colored coated steel sheets using galvanized steel sheets as a base material have zinc protection, and the organic coating on the zinc layer provides a covering and isolating effect, preventing the steel sheet from rusting and extending its lifespan compared to galvanized steel sheets. It has been reported that the lifespan of coated steel sheets is 50% longer than that of galvanized steel sheets. However, in different regions and applications, using the same
