While most other building materials are impeded in some way or another by building code restrictions, steel frame structures have evolved with time. This means that the building techniques employed during the construction of steel frame structures, which include mansards, parapets, and simulated exteriors, pass all building regulations with ease. Construction companies using steel frame structures also tend to employ specialists in the building industry to offer their advice and suggest solutions concerning building restrictions. Engineers are also involved to ensure that the steel frame structures to be used are pre-fabricated and engineered to particular coding requirements.
Compared to steel frame structures, other building materials involves high labour costs. This is attributed to the fact that while wood, stone, and brick are custom fitted and subsequently rather expensive, steel frame structures can simply be bolted together.
