EPiC database - Hot rolled structural steel

This material is part of the free Environmental Performance in Construction (EPiC) Database. The EPiC Database contains embodied environmental flow coefficients for 250+ construction materials using a comprehensive hybrid life cycle inventory approach.Steel is a ferrous metal and is an alloy of iron and carbon, as well as potential other elements. It has a very high tensile strength. Steel has been used in the construction industry for over a century.The core material for making steel is iron, which is found in iron ore. Iron is extracted from iron ore in blast furnaces through the smelting process, while controlling for the content of carbon. The molten steel is usually further processed before being cast for its final use.Steel is commonly used in the construction industry, mainly as a structural material. Hot rolled structural steel is used to produce a range of structural elements, such as reinforcement bars, I-beams and railroad tracks.

本资料系自由环境绩效在建筑（EPiC）数据库的一部分。该EPiC数据库包含250种以上建筑材料的累积环境流动系数，采用全面混合生命周期清单方法进行编制。钢铁作为一种铁质金属，是由铁和碳以及其他潜在元素组成的合金，具有极高的抗拉强度。钢铁在建筑行业中的应用已有超过一个世纪的历史。制造钢铁的核心材料为铁，铁矿石中富含铁。通过高炉熔炼过程，在控制碳含量的同时从铁矿石中提取铁，熔融钢铁通常在铸造其最终用途之前进行进一步加工。钢铁在建筑行业中得到广泛应用，主要用作结构材料。热轧结构钢用于生产各种结构元件，如钢筋、工字钢和铁路轨道。
