=== Portal frame ===
Steel portal frames are capable of spanning large distances. They are
used in the construction of factories and warehouses, and other low-rise
buildings that require wide spans. Wall and roof bracing is normally
provided in selected bays, often at the end of buildings. Additional
vertical column or beam sections may be introduced at the gables
(wind posts) to support cladding on end walls.
Roof beams (rafters) and columns are usually fabricated from rolled
steel sections, while purlins and cladding rails are usually in light
steel sections. Liner trays may be used as an alternative to cladding
rails.
Cladding materials include built-up cladding systems (as shown),
composite cladding panels, and masonry.
Small single storey industrial buildings can also be constructed
using light steel sections for the columns and rafters
