Structural elements must be noncombustible and rated for fire resistance within the boundaries of the code. While these buildings generally have fire suppression systems, they are prone to collapse when flames expose their metal roofs to high temperatures. Materials with no fire-resistance ratings, such as untreated wood, may be used only in limited quantities. o Domes, and. Construction type II (Noncombustible or Limited Combustible) -Half the Fire-resistive rating of type I (2 hours) -Used when fire risk is expected to be low -Materials -Metal framing members and Metal cladding.
