The first option, companies seek to add graphene to steel, making an alloy. This idea helps integrate the property of the steel. Not only does graphene help to strengthen the steel, it also reduces the weight. However, manufacturers have yet to develop a solution to execute this plan, so this is a plan for the future.
The second option, construction companies use graphene to coat the steel’s outermost layer to make it anti-corrosive. Companies reason that the material has the ability to resist penetration from other matters, including liquid and gas. With a graphene coating, they prevent the steel from rusting, thus increasing its life span.
