Why would anyone in their right mind build a gable roof in place instead of buying prefab trusses or building the trusses by hand on the ground and have them lifted in place by a crane?
Because pre-fab trusses are inevitably inferior in terms of materials and workmanshipAnything mass produced for mass construction is built to minimum code standardsI've seen newly assembled pre-fab houses with sagging roofs before the first owner even moves in.even on some 8,000 sq/ft starter-castle-type housesThere's a much better chance of solid construction with a stick-built truss.
YesThere are many alloys of Titanium and AluminiumMost of the alloys of Ti/Al have applications in the aerospace industry as construction material for aeroplanes and space craftspecifically Aluminium/Titanium Alloys are often used for the construction of fuselage and wings, and another application of this alloy is used in bicycle frames.
