Steel in architecture and civil engineering projects is to material, especially as more and more developments are made with stainless steel alloys. In modern construction, specific core properties of the material have made it indispensable. Many steel alloys offer tremendous strength, much more significant than pure iron. Steel also provides flexibility and formability, the two traits that engineers love. Stainless steel is easily recyclable in this modern era of sustainable building and green architecture. It can be used in applications that accentuate natural light, reducing energy costs.
