Metal building systems (or steel building systems in Canada) are professionally engineered structures that provide cost-effective and efficient low-rise buildings. All major metal building system manufacturers utilize CADD tools to custom design each building system and all building components depending on the customer's needs and specifications and on the local and national building codes. The basic elements of the metal building system include primary rigid frames, secondary members such as wall girts and roof purlins, cladding and bracing. These elements are engineered and designed to act as an integrated building system
The primary rigid frames are typically designed and constructed in accordance with standardima koje je razvio Američki institut za čeličnu konstrukciju in the United States and the Kanadski institut za izgradnju čeličnog lima. In North America, the secondary framing is typically designed and constructed in accordance with standarde koje je razvio Američki institut za željezo i čelik.
Metalni građevinski sistemi se koriste u gotovo svakoj zamislivoj primjeni. Naći ćete ih u industrijskim aplikacijama kao što su složeni proizvodni pogoni, skladišta i distributivni centri. Koriste se u maloprodajnim objektima, trgovačkim centrima, motelima, prodajnim salonima automobila, uredskim kompleksima, hangarima za avione i arenama. Koriste se i u školama, bibliotekama, crkvama, medicinskim ustanovama i državnim zgradama.
