Re: Recycled materials

[Subject Prev][Subject Next][Thread Prev][Thread Next]
Most of the steel used in bar joist is recycled so I assume you could use a
lot of bar joists and fit the spec.  Also I understand most angle materials
is recycled.

Maybe someone can correct me but I think the reason for the evident demise
of A36 and the rise of the "dual-cert" material and its spec is the amount
of recycled material in the steel pipeline.  I await correction or
