Does anyone know much about building in steel? There's a lot of it going on, I'm guessing the labour cost hike and low steel price is making it more affordable than concrete.
It also seems a lot easier than pouring columns and all the hassle involved. You just need a decent welder.
In Australia they send plans to China, where all the steel is cut, with bolt holes added. Then they just bolt it together.
I wonder if a Thai steel yard may be willing to cut the steel? Then it just needs to welded on site. This would prevent those costly mistakes that we all know and love.
