Article 5

This article talks about when and why concrete is better than steel in construction. It fairly suggests that below 50,000 sqr feet, steel is generally a better product ot use as the main material in the construction as the cranes needed to be used wont be for as long as if it were a concrete project. However when the job is over 50,000 sq ft concrete is a better solution as it is a cheper raw material and the fact that the cost of crane hire is negated by the concretes cheap cost and ease of construction on site.
