EPiC database - Steel hollow section extruded

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 extruded into hollow sections.Hollow sections of steel are commonly used in the construction industry, mainly for structural purposes.

该素材为免费环境性能在建筑（EPiC）数据库的一部分。EPiC数据库采用全面混合生命周期清单方法，包含了250多种建筑材料的环境累积流量系数。钢铁是一种铁磁性金属，是铁与碳的合金，以及可能的其他元素。它具有极高的抗拉强度。钢铁在建筑行业中已使用超过一个世纪。制造钢铁的核心材料为铁，铁矿石中存在铁。铁通过高炉熔炼过程从铁矿石中提取，同时控制碳的含量。熔融的钢通常在挤出成空心截面之前进行进一步加工。钢制空心截面在建筑行业中广泛应用，主要用于结构用途。
