Steel is one of the most readily available, affordable, durable and strong building materials available. It’s easily formed into virtually any shape and can be finished to address an amazingly wide range of needs.
What’s even better is the fact that steel is 100% recyclable, and can be recycled virtually forever. With careful planning, there’s never any reason for steel to end up in a landfill. And, compared with the cost of producing new material to perform the same tasks, recycling steel saves energy and reduces CO2 emissions. (In the past 30 years, the amount of energy required to produce a metric ton of steel has been reduced by 50%)
Then there’s the fact that steel is not done developing! There are new advances in producing and refining steel for more uses and with better performance characteristics all the time.
