The China Iron And Steel Association Held A Symposium on jointly Promoting The Development Of Steel Structure Buildings
Recently, a symposium on the coordinated promotion of steel structure development was held in Ma'anshan, Anhui, hosted by the China Iron and Steel Association and organized by Ma'anshan Iron and Steel Co., Ltd., with the theme of "Integration and Innovation - High-efficiency Steel to Help Steel Structure "Good House" Construction". Xia Nong, Vice President of the China Iron and Steel Association, Zhang Feng, Chief Engineer of the Science and Technology and Industrialization Development Center of the Ministry of Housing and Urban-Rural Development, Qi Weidong, Secretary of the Party Committee and Chairman of Ma'anshan Iron and Steel, and more than 80 expert representatives from 37 steel structure building design and construction related enterprises, scientific research institutes, and 7 steel companies gathered together to discuss the working methods and paths for the coordinated development of the steel structure building industry chain.

Wang Tie, Director of the Carbon Market Division of the Department of Climate Change of the Ministry of Ecology and Environment, stood at the podium of the 2025 International Forum on Carbon Emission Reduction in the Building Materials Industry and announced that the three industries of steel, cement and aluminum smelting will start the first carbon emission quota allocation and clearance and compliance work. This policy will cover an additional 3 billion tons of carbon dioxide equivalent greenhouse gas emissions, increasing the proportion of carbon emissions controlled by the national carbon market from 40% to more than 60% of the national total.

Galvanized steel pipe is a steel pipe made by coating a layer of zinc on the surface of ordinary steel pipe (carbon steel pipe). Zinc has active chemical properties and can form a dense oxide film, thereby isolating oxygen and moisture and preventing the steel pipe from rusting.GI steel pipe is a metal pipe with zinc coating on the surface of ordinary steel pipe to prevent corrosion. It is divided into hot-dip galvanizing and electro-galvanizing. Hot-dip galvanized steel pipes are immersed in molten zinc liquid (about 450°C) to form a thicker zinc layer (50-150μm), which has strong corrosion resistance and is suitable for outdoor or humid environments; electro-galvanized steel pipe adopts electrolysis process, the zinc layer is thinner (5-30μm), the cost is lower, and it is mostly used indoors.
