Graphical Construction Glossary >> Roofs and roofing. >> Roof Framing >> steel purlin
The advantages of steel as a purlin material over timber are obvious.
It should be noted here that laminated timber engineered beams are also available in long lengths, but they are too deep in section to be even considered as over purlins for directly fixing sheeting to. Support purlins yes.
The whole of this roof framing for an elevated deck is constructed with RHS material, including the steel purlins. Note that the ends have been capped.
