Steel is significantly more structurally efficientthanconcrete(fy=35MPa)orwood(fy= 40MPa). Whenitcomestoembodiedcarbon,the quantity of material is directly correlated with the quantity of CO 2emissions. Increasing the use of grade 65 (450MPa) steel vs. grade 44 (300MPa) or grade 50 (350MPa) has an almost negligible effect onembodiedcarbonperkgofsteelandcan allow for less material to be used in construction. High-strength steel can be produced using either BOF or EAF methods. Current strength steels for construction have already superseded steel grades thathadpreviouslybeenconsideredstandard, such as grade 36 (250MPa). Designing with higher strengths allows for more design flexibility and puts the engineer in the drivers seat. High-strengthsteelwillonlybecomemore available as more engineers start specifying it on their projects.
