Abstract In China, the construction steel consumption is the biggest. The rapid development of construction industry provides a wide range of markets for the development and application of construction steel. The development and application of construction steel varieties has been made great progress. But compared with developed countries, scientific research and technology development for the construction steel is still relatively backward. This includes: Lower level of development capabilities of new kind of steel products and applied technology; The low proportion of consumer applications for high-performance high-strength steel; Amendment cycle longer for national standards and technical specifications of construction steel and so on. The technical content of construction steel is relatively low，it belongs to the more basic, lower-end steel. The scientific research and development are relative shortage of capital investment. Variety of construction steel technology indicators still need to be further improved, especially in seismic performance indicators is required depth study. In this paper, development and international technology development trends for the current plate steel, weathering steel, fire-resistant steel and steel rebars was analysis.
