EPiC database - Hot rolled galvanised 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. Galvanisation can be used to apply a coat of zinc crystals on the surface of the steel to significantly improve its resistance to corrosion.Steel is commonly used in the construction industry, mainly as a structural material. Hot rolled galvanised steel is used to produce elements for the outdoors, such as poles, pipes, and decking.本材料隶属于免费开放的建筑环境性能（Environmental Performance in Construction, EPiC）数据库。该数据库采用全面的混合生命周期清单分析方法，收录了250余种建筑材料的隐含环境流系数。 钢材属于铁基金属，是以铁与碳为主要成分、可掺杂其他元素的合金，具备极高的抗拉强度。钢材在建筑行业的应用已有百余年历史。 钢材生产的核心原料为铁矿石中提取的铁。工业上通过高炉冶炼工艺从铁矿石中提炼生铁，并严格控制碳元素含量。 熔融态钢材通常需经过进一步加工后，方可浇铸成型以满足最终使用需求。 可通过镀锌工艺在钢材表面镀覆一层锌晶体层，以此显著提升其抗腐蚀性能。 钢材在建筑行业应用广泛，主要作为结构材料使用。 热浸镀锌钢材常被用于制造户外构件，例如立柱、管道及露台地板板材。
