the floor plans and ceiling heights can be changed freely, and so it is easy to put in special sick rooms, classrooms, and heavy testing machines
the steel parts are cut very exactly in a factory and then bolted together at the site, which takes away the need for hard on-site welding, and so delays are gone and the building is done fast
the hot-dip zinc coating makes a very strong cover that stops water and cleaning chemicals, and the structure stays good for more than 50 years with no upkeep
using advanced pre-made modules, the whole building time is cut by up to half compared to the usual concrete way, which brings important public buildings into use months earlier
this is made for places with many people, and it meets the strict building codes well while the design is also kind to the environment, balanced smoothly
by using very strong steel, the building can hold heavy loads and resist earthquakes well, and in extreme conditions it works better than usual wood or brick buildings
