1.1 Steel Manufacturing Process Steel production involves several processing stages including iron making‚ primary and secondary steel making‚ casting and hot rolling. These are followed by some of the following fabrication processes: cold rolling‚ forming‚ forging‚ joining‚ machining‚ coating and/or heat treatment. Steels can be made either from raw materials (e.g. iron ore‚ coal and limestone) or by recycling steel scrap. In response to the requirements of society‚ steel processing is

If GRFP is utilized‚ the portal frame section can be design to consume less steel because GFRP is light weight. Since it has a very high strength to weight ratio‚ being light weight‚ GFRP does not make it loose its strength. Regardless‚ this material still possesses less strength compared to steel. This material is also environment and corrosion resistance‚ so when used as purlins or
