So we replaced the larger old Farm House looking inherited mailbox with a skinny metal one from HD.

Thanks for the info. in maine we have added risk and weight of snow and ice. risky add more weight to aging roof. ive done both. but prefer rentals get metal roofs so no build up no replacement for 30-50 years. btw 1 inch ice equals 12 inch fresh snow.  

Hello BP Friends-I am working on 2 rehabs in South Philadelphia and looking for a metal railing fabricator in the area. 

If this duct is accessible and large enough you may look at installing some sheet metal within the existing duct, if you go this route, which would essentially provide 3 separate 'flues' to your spaces. 

They're metal.

I just googled and pasting the first link i saw: http://www.hudsonvalleyepoxyflooring.com/metallic-...It is not cheap as compared to vinyl planks but long lasting. 

did the metal manu say this was ok?

This was a 2,350sq ft metal building that sat on 1 acre.

I ended up getting all my windows wrapped in metal before I had it tested.

It needed replacing because the tenant had scrubbed through the enamel and dented the sheet metal attempting to “clean” it.
